Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

NASL family SuSE Local Security Checks NASL id SUSE_SU-2014-0446-1.NASL description The SUSE Linux Enterprise Server 11 Service Pack 1 LTSS Xen hypervisor and toolset have been updated to fix various security issues and some bugs. The following security issues have been addressed : XSA-84: CVE-2014-1894: Xen 3.2 (and presumably earlier) exhibit both problems with the overflow issue being present for more than just the suboperations listed above. (bnc#860163) XSA-84: CVE-2014-1892 CVE-2014-1893: Xen 3.3 through 4.1, while not affected by the above overflow, have a different overflow issue on FLASK_{GET,SET}BOOL and expose unreasonably large memory allocation to arbitrary guests. (bnc#860163) XSA-84: CVE-2014-1891: The FLASK_{GET,SET}BOOL, FLASK_USER and FLASK_CONTEXT_TO_SID suboperations of the flask hypercall are vulnerable to an integer overflow on the input size. The hypercalls attempt to allocate a buffer which is 1 larger than this size and is therefore vulnerable to integer overflow and an attempt to allocate then access a zero byte buffer. (bnc#860163) XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between locked instructions and write-combined memory types, which allows local users to cause a denial of service (system hang) via a crafted application, aka the errata 793 issue.

This is CVE-2013-1952 / XSA-49. - x86: make page table handling error paths preemptible ... as they may take significant amounts of time. This requires cloning the tweaked continuation logic from do_mmuext_op to do_mmu_update. Note that in mod_l[34]_entry a negative 'preemptible' value gets passed to put_page_from_l[34]e now, telling the callee to store the respective page in current->arch.old_guest_table (for a hypercall continuation to pick up), rather than carrying out the put right away. This is going to be made a little more explicit by a subsequent cleanup patch. This is part of CVE-2013-1918 / XSA-45. (CVE-2013-1918) - x86: make page table unpinning preemptible ... as it may take significant amounts of time. Since we can't re-invoke the operation in a second attempt, the continuation logic must be slightly tweaked so that we make sure do_mmuext_op gets run one more time even when the preempted unpin operation was the last one in a batch.

This is part of CVE-2013-1918 / XSA-45. (CVE-2013-1918) - x86: make vcpu_reset preemptible ... as dropping the old page tables may take significant amounts of time.

(CVE-2013-1918) - x86: make vcpu_destroy_pagetables preemptible ... as it may take significant amounts of time. The function, being moved to mm.c as the better home for it anyway, and to avoid having to make a new helper function there non-static, is given a 'preemptible' parameter temporarily (until, in a subsequent patch, its other caller is also being made capable of dealing with preemption). This is part of CVE-2013-1918 / XSA-45. (CVE-2013-1918) - Fix rcu domain locking for transitive grants When acquiring a transitive grant for copy then the owning domain needs to be locked down as well as the granting domain. This was being done, but the unlocking was not. The acquire code now stores the struct domain * of the owning domain (rather than the domid) in the active entry in the granting domain. The release code then does the unlock on the owning domain. Note that I believe I also fixed a bug where, for non-transitive grants the active entry contained a reference to the acquiring domain rather than the granting domain. From my reading of the code this would stop the release code for transitive grants from terminating its recursion correctly. Also, for non-transitive grants we now avoid incorrectly recursing in __release_grant_for_copy. This is CVE-2013-1964 / XSA-50.

NASL family Debian Local Security Checks NASL id DEBIAN_DSA-2666.NASL description Multiple vulnerabilities have been discovered in the Xen hypervisor. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2013-1918 ( XSA 45) several long latency operations are not preemptible. Some page table manipulation operations for PV guests were not made preemptible, allowing a malicious or buggy PV guest kernel to mount a denial of service attack affecting the whole system. - CVE-2013-1952 ( XSA 49) VT-d interrupt remapping source validation flaw for bridges. Due to missing source validation on interrupt remapping table entries for MSI interrupts set up by bridge devices, a malicious domain with access to such a device can mount a denial of service attack affecting the whole system. - CVE-2013-1964 ( XSA 50) grant table hypercall acquire/release imbalance. When releasing a particular, non-transitive grant after doing a grant copy operation, Xen incorrectly releases an unrelated grant reference, leading possibly to a crash of the host system. Furthermore information leakage or privilege escalation cannot be ruled out. last seen 2020-03-17 modified 2013-05-13 plugin id 66383 published 2013-05-13 reporter This script is Copyright (C) 2013-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/66383 title Debian DSA-2666-1 : xen - several vulnerabilities code #%NASL_MIN_LEVEL 80502 # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Debian Security Advisory DSA-2666.

The following security issues have been fixed : - Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier were not preemptible, which allowed local PV kernels to cause a denial of service via vectors related to deep page table traversal. (CVE-2013-1918) - Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, did not properly check the source when accessing a bridge devices interrupt remapping table entries for MSI interrupts, which allowed local guest domains to cause a denial of service (interrupt injection) via unspecified vectors. (CVE-2013-1952) - A information leak in the XSAVE/XRSTOR instructions could be used to determine state of floating point operations in other domains. (CVE-2013-2076) - A denial of service (hypervisor crash) was possible due to missing exception recovery on XRSTOR, that could be used to crash the machine by PV guest users. (CVE-2013-2077) - A denial of service (hypervisor crash) was possible due to missing exception recovery on XSETBV, that could be used to crash the machine by PV guest users. (CVE-2013-2078) - Systems which allow untrusted administrators to configure guest vcpu affinity may be exploited to trigger a buffer overrun and corrupt memory. (CVE-2013-2072) - Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, did not clear the NT flag when using an IRET after a SYSENTER instruction, which allowed PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction. (CVE-2013-1917) - Xen 4.2.x and 4.1.x did not properly restrict access to IRQs, which allowed local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to last seen 2020-06-05 modified 2013-06-26 plugin id 66985 published 2013-06-26 reporter This script is Copyright (C) 2013-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/66985 title SuSE 11.2 Security Update : Xen (SAT Patch Number 7798) NASL family OracleVM Local Security Checks NASL id ORACLEVM_OVMSA-2013-0036.NASL description The remote OracleVM system is missing necessary patches to address critical security updates : - VT-d: don last seen 2020-06-01 modified 2020-06-02 plugin id 79505 published 2014-11-26 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/79505 title OracleVM 3.2 : xen (OVMSA-2013-0036)
