Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

It is, therefore, affected by multiple vulnerabilities : - A new subclass of speculative execution side channel vulnerabilities, known as Microarchitectural Data Sampling, exist in Windows. An attacker who successfully exploited these vulnerabilities may be able to read privileged data across trust boundaries. In shared resource environments (such as exists in some cloud services configurations), these vulnerabilities could allow one virtual machine to improperly access information from another. In non-browsing scenarios on standalone systems, an attacker would need prior access to the system or an ability to run a specially crafted application on the target system to leverage these vulnerabilities. (CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130) - An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2019-0892) - A denial of service vulnerability exists when .NET Framework and .NET Core improperly process RegEx strings. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET Framework (or .NET core) application. The update addresses the vulnerability by correcting how .NET Framework and .NET Core applications handle RegEx string processing. (CVE-2019-0820) - An elevation of privilege vulnerability exists in Microsoft Windows when a man-in-the-middle attacker is able to successfully decode and replace authentication request using Kerberos, allowing an attacker to be validated as an Administrator. The update addresses this vulnerability by changing how these requests are validated. (CVE-2019-0734) - An elevation of privilege vulnerability exists when the Windows Kernel improperly handles key enumeration. An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system. A locally authenticated attacker could exploit this vulnerability by running a specially crafted application. The security update addresses the vulnerability by helping to ensure that the Windows Kernel properly handles key enumeration. (CVE-2019-0881) - An elevation of privilege vulnerability exists in Microsoft Windows when Windows fails to properly handle certain symbolic links. An attacker who successfully exploited this vulnerability could potentially set certain items to run at a higher level and thereby elevate permissions. (CVE-2019-0936) - An elevation of privilege vulnerability exists when the Storage Service improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges on the victim system. (CVE-2019-0931) - A remote code execution vulnerability exists when Microsoft Windows OLE fails to properly validate user input. An attacker could exploit the vulnerability to execute malicious code. (CVE-2019-0885) - A remote code execution vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in the memory. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2019-0903) - A memory corruption vulnerability exists in the Windows Server DHCP service when processing specially crafted packets. An attacker who successfully exploited the vulnerability could run arbitrary code on the DHCP server. (CVE-2019-0725) - A denial of service vulnerability exists when .NET Framework improperly handles objects in heap memory. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. (CVE-2019-0864) - An information disclosure vulnerability exists when Windows Hyper-V on a host operating system fails to properly validate input from an authenticated user on a guest operating system. (CVE-2019-0886) - An elevation of privilege vulnerability exists in the Unified Write Filter (UWF) feature for Windows 10 when it improperly restricts access to the registry. An attacker who successfully exploited the vulnerability could make changes to the registry keys protected by UWF without having administrator privileges. (CVE-2019-0942) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2019-0758, CVE-2019-0882, CVE-2019-0961) - An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. (CVE-2019-0707) - A security feature bypass vulnerability exists in Windows Defender Application Control (WDAC) which could allow an attacker to bypass WDAC enforcement. An attacker who successfully exploited this vulnerability could circumvent Windows PowerShell Constrained Language Mode on the machine. (CVE-2019-0733) - An elevation of privilege vulnerability exists in the way Windows Error Reporting (WER) handles files. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with administrator privileges. (CVE-2019-0863) - A denial of service vulnerability exists when .NET Framework or .NET Core improperly handle web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET Framework or .NET Core web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the .NET Framework or .NET Core application. The update addresses the vulnerability by correcting how .NET Framework or .NET Core web applications handles web requests. (CVE-2019-0980, CVE-2019-0981) - A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory.

This is related to a capability check for the wrong task (bnc#1128166). CVE-2013-0216: The Xen netback functionality allowed guest OS users to cause a denial of service (loop) by triggering ring pointer corruption (bnc#800280). CVE-2013-0231: The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen allowed guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages. (bnc#801178). CVE-2012-3430: The rds_recvmsg function in net/rds/recv.c did not initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a recvfrom or recvmsg system call on an RDS socket (bnc#773383). CVE-2012-3412: The sfc (aka Solarflare Solarstorm) driver allowed remote attackers to cause a denial of service (DMA descriptor consumption and network-controller outage) via crafted TCP packets that trigger a small MSS value (bnc#774523). CVE-2013-0160: The kernel allowed local users to obtain sensitive information about keystroke timing by using the inotify API on the /dev/ptmx device (bnc#797175). CVE-2013-1979: The scm_set_cred function in include/net/scm.h uses incorrect uid and gid values during credentials passing, which allowed local users to gain privileges via a crafted application (bnc#816708).

An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2019-0930) - A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2019-0884, CVE-2019-0911, CVE-2019-0918) - A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory. (CVE-2019-0889, CVE-2019-0890, CVE-2019-0891, CVE-2019-0893, CVE-2019-0894, CVE-2019-0895, CVE-2019-0896, CVE-2019-0897, CVE-2019-0898, CVE-2019-0899, CVE-2019-0900, CVE-2019-0901, CVE-2019-0902) - A denial of service vulnerability exists when .NET Framework improperly handles objects in heap memory. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. (CVE-2019-0864) - An elevation of privilege vulnerability exists in the Unified Write Filter (UWF) feature for Windows 10 when it improperly restricts access to the registry. An attacker who successfully exploited the vulnerability could make changes to the registry keys protected by UWF without having administrator privileges. (CVE-2019-0942) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2019-0758, CVE-2019-0882, CVE-2019-0961) - An elevation of privilege vulnerability exists in Microsoft Edge that could allow an attacker to escape from the AppContainer sandbox in the browser. An attacker who successfully exploited this vulnerability could gain elevated privileges and break out of the Edge AppContainer sandbox. The vulnerability by itself does not allow arbitrary code to run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (for example a remote code execution vulnerability and another elevation of privilege vulnerability) to take advantage of the elevated privileges when running. The security update addresses the vulnerability by modifying how Microsoft Edge handles sandboxing. (CVE-2019-0938) - An elevation of privilege vulnerability exists in Microsoft Windows when Windows fails to properly handle certain symbolic links. An attacker who successfully exploited this vulnerability could potentially set certain items to run at a higher level and thereby elevate permissions. (CVE-2019-0936) - An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. (CVE-2019-0707) - An elevation of privilege vulnerability exists in Microsoft Windows when a man-in-the-middle attacker is able to successfully decode and replace authentication request using Kerberos, allowing an attacker to be validated as an Administrator. The update addresses this vulnerability by changing how these requests are validated. (CVE-2019-0734) - A security feature bypass vulnerability exists in Windows Defender Application Control (WDAC) which could allow an attacker to bypass WDAC enforcement. An attacker who successfully exploited this vulnerability could circumvent Windows PowerShell Constrained Language Mode on the machine.

The forward can also happen to a faulting or assisting load operation for a different memory address, which can cause an issue under certain conditions. Store buffers are partitioned between Hyper-Threads so cross thread forwarding is not possible. But if a thread enters or exits a sleep state the store buffer is repartitioned which can expose data from one thread to the other. MFBDS leaks Fill Buffer Entries. Fill buffers are used internally to manage L1 miss situations and to hold data which is returned or sent in response to a memory or I/O operation. Fill buffers can forward data to a load operation and also write data to the cache. When the fill buffer is deallocated it can retain the stale data of the preceding operations which can then be forwarded to a faulting or assisting load operation, which can cause an issue under certain conditions. Fill buffers are shared between Hyper-Threads so cross thread leakage is possible. MLDPS leaks Load Port Data. Load ports are used to perform load operations from memory or I/O. The received data is then forwarded to the register file or a subsequent operation. In some implementations the Load Port can contain stale data from a previous operation which can be forwarded to faulting or assisting loads under certain conditions, which again can cause an issue eventually. Load ports are shared between Hyper-Threads so cross thread leakage is possible. last seen 2020-06-01 modified 2020-06-02 plugin id 125092 published 2019-05-15 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125092 title Amazon Linux AMI : kernel (ALAS-2019-1205) (MDSUM/RIDL) (MFBDS/RIDL/ZombieLoad) (MLPDS/RIDL) (MSBDS/Fallout) NASL family SuSE Local Security Checks NASL id SUSE_SU-2019-1910-1.NASL description This update for ucode-intel fixes the following issues : This update contains the Intel QSR 2019.1 Microcode release (bsc#1111331) Four new speculative execution information leak issues have been identified in Intel CPUs.

CVE-2018-12207 It was discovered that on Intel CPUs supporting hardware virtualisation with Extended Page Tables (EPT), a guest VM may manipulate the memory management hardware to cause a Machine Check Error (MCE) and denial of service (hang or crash). The guest triggers this error by changing page tables without a TLB flush, so that both 4 KB and 2 MB entries for the same virtual address are loaded into the instruction TLB (iTLB). This update implements a mitigation in KVM that prevents guest VMs from loading 2 MB entries into the iTLB.

NASL id MDS_KERNEL_REPORTING_LINUX.NASL description According to the remote Linux kernel, this system is vulnerable to the following information disclosure vulnerabilities: - MSBDS leaks Store Buffer Entries which can be speculatively forwarded to a dependent load (store-to-load forwarding) as an optimization. The forward can also happen to a faulting or assisting load operation for a different memory address, which can cause an issue under certain conditions. Store buffers are partitioned between Hyper-Threads so cross thread forwarding is not possible. But if a thread enters or exits a sleep state the store buffer is repartitioned which can expose data from one thread to the other. (MSBDS/Fallout) (CVE-2018-12126) - MLDPS leaks Load Port Data. Load ports are used to perform load operations from memory or I/O. The received data is then forwarded to the register file or a subsequent operation. In some implementations the Load Port can contain stale data from a previous operation which can be forwarded to faulting or assisting loads under certain conditions, which again can cause an issue eventually. Load ports are shared between Hyper-Threads so cross thread leakage is possible. (MLPDS/RIDL) (CVE-2018-12127) MFBDS leaks Fill Buffer Entries. Fill buffers are used internally to manage L1 miss situations and to hold data which is returned or sent in response to a memory or I/O operation. Fill buffers can forward data to a load operation and also write data to the cache. When the fill buffer is deallocated it can retain the stale data of the preceding operations which can then be forwarded to a faulting or assisting load operation, which can cause an issue under certain conditions. Fill buffers are shared between Hyper-Threads so cross thread leakage is possible. (MFBDS/RIDL/ZombieLoad) (CVE-2018-12130) - MDSUM is a special case of MSBDS, MFBDS and MLPDS. An uncacheable load from memory that takes a fault or assist can leave data in a microarchitectural structure that may later be observed using one of the same methods used by MSBDS, MFBDS or MLPDS. (MDSUM/RIDL) (CVE-2019-11091) To address these issues, update the kernel packages on your Linux system, disable Simultaneous Multi-Threading (SMT) or otherwise configure it to a non-vulnerable state, and apply microcode fixes to your hardware.

This allows local users to obtain sensitive information, cause a denial of service (DoS), or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls.(CVE-2019-11599) - The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions.(CVE-2019-11486) - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs. As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it is possible for the specified target task to perform an execve() syscall with setuid execution before perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged execve() calls.(CVE-2019-3901) - The atyfb_ioctl function in drivers/video/fbdev/aty/atyfb_base.c in the Linux kernel through 4.12.10 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory by reading locations associated with padding bytes.(CVE-2017-14156) - A flaw was found in the Linux kernel last seen 2020-05-06 modified 2019-05-29 plugin id 125515 published 2019-05-29 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125515 title EulerOS 2.0 SP5 : kernel (EulerOS-SA-2019-1588) NASL family Scientific Linux Local Security Checks NASL id SL_20190514_KERNEL_ON_SL7_X.NASL description Security Fix(es) : - A flaw was found in the implementation of the last seen 2020-03-18 modified 2019-05-16 plugin id 125203 published 2019-05-16 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125203 title Scientific Linux Security Update : kernel on SL7.x x86_64 (20190514) (MDSUM/RIDL) (MFBDS/RIDL/ZombieLoad) (MLPDS/RIDL) (MSBDS/Fallout) NASL family SuSE Local Security Checks NASL id OPENSUSE-2019-1403.NASL description This update for xen fixes the following issues : Four new speculative execution information leak issues have been identified in Intel CPUs.

The guest triggers this error by changing page tables without a TLB flush, so that both 4 KB and 2 MB entries for the same virtual address are loaded into the instruction TLB (iTLB). This update implements a mitigation in KVM that prevents guest VMs from loading 2 MB entries into the iTLB. This will reduce performance of guest VMs. Further information on the mitigation can be found at or in the linux-doc-4.9 or linux-doc-4.19 package. A qemu update adding support for the PSCHANGE_MC_NO feature, which allows to disable iTLB Multihit mitigations in nested hypervisors will be provided via DSA 4566-1.
