Vulnerable Configurations
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.

NASL family SuSE Local Security Checks NASL id OPENSUSE-2019-1226.NASL description This update for xen fixes the following issues : Security issues fixed : - CVE-2018-19967: Fixed HLE constructs that allowed guests to lock up the host, resulting in a Denial of Service (DoS). (XSA-282) (bsc#1114988) - CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() found in slirp (bsc#1123157). - Fixed an issue which could allow malicious or buggy guests with passed through PCI devices to be able to escalate their privileges, crash the host, or access data belonging to other guests. Additionally memory leaks were also possible (bsc#1126140). - Fixed a race condition issue which could allow malicious PV guests to escalate their privilege to that of the hypervisor (bsc#1126141). - Fixed an issue which could allow a malicious unprivileged guest userspace process to escalate its privilege to that of other userspace processes in the same guest and potentially thereby to that of the guest operating system (bsc#1126201). - CVE-2019-9824: Fixed an information leak in SLiRP networking implementation which could allow a user/process to read uninitialised stack memory contents (bsc#1129623). - CVE-2018-19961 CVE-2018-19962: Fixed insufficient TLB flushing / improper large page mappings with AMD IOMMUs (XSA-275)(bsc#1115040). - CVE-2018-19965: Fixed denial of service issue from attempting to use INVPCID with a non-canonical addresses (XSA-279)(bsc#1115045). - CVE-2018-19966: Fixed issue introduced by XSA-240 that could have caused conflicts with shadow paging (XSA-280)(bsc#1115047). - Fixed an issue which could allow malicious PV guests may cause a host crash or gain access to data pertaining to other guests.Additionally, vulnerable configurations are likely to be unstable even in the absence of an attack (bsc#1126198). - Fixed multiple access violations introduced by XENMEM_exchange hypercall which could allow a single PV guest to leak arbitrary amounts of memory, leading to a denial of service (bsc#1126192). - Fixed an issue which could allow malicious 64bit PV guests to cause a host crash (bsc#1127400). - Fixed an issue which could allow malicious or buggy x86 PV guest kernels to mount a Denial of Service attack affecting the whole system (bsc#1126197). - Fixed an issue which could allow an untrusted PV domain with access to a physical device to DMA into its own pagetables leading to privilege escalation (bsc#1126195). - Fixed an issue which could allow a malicious or buggy x86 PV guest kernels can mount a Denial of Service attack affecting the whole system (bsc#1126196). Other issues addressed : - Upstream bug fixes (bsc#1027519) - Fixed an issue where live migrations were failing when spectre was enabled on xen boot cmdline (bsc#1116380). - Fixed an issue where setup of grant_tables and other variables may fail (bsc#1126325). - Fixed a building issue (bsc#1119161). - Fixed an issue where xpti=no-dom0 was not working as expected (bsc#1105528). - Packages should no longer use /var/adm/fillup-templates (bsc#1069468). - Added Xen cmdline option last seen 2020-06-01 modified 2020-06-02 plugin id 124147 published 2019-04-18 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/124147 title openSUSE Security Update : xen (openSUSE-2019-1226) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from openSUSE Security Update openSUSE-2019-1226. # # The text description of this plugin is (C) SUSE LLC. # include("compat.inc"); if (description) { script_id(124147); script_version("1.2"); script_cvs_date("Date: 2020/01/23"); script_cve_id("CVE-2018-19665", "CVE-2018-19961", "CVE-2018-19962", "CVE-2018-19965", "CVE-2018-19966", "CVE-2018-19967", "CVE-2019-6778", "CVE-2019-9824"); script_name(english:"openSUSE Security Update : xen (openSUSE-2019-1226)"); script_summary(english:"Check for the openSUSE-2019-1226 patch"); script_set_attribute( attribute:"synopsis", value:"The remote openSUSE host is missing a security update." ); script_set_attribute( attribute:"description", value: "This update for xen fixes the following issues : Security issues fixed : - CVE-2018-19967: Fixed HLE constructs that allowed guests to lock up the host, resulting in a Denial of Service (DoS).
