Vulnerable Configurations
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 Red Hat Local Security Checks NASL id REDHAT-RHSA-2009-1024.NASL description Updated kernel packages are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 4. This is the eighth regular update. These updated packages fix two security issues, hundreds of bugs, and add numerous enhancements. Space precludes a detailed description of each of these in this advisory. Refer to the Red Hat Enterprise Linux 4.8 Release Notes for information on 22 of the most significant of these changes. For more detailed information on specific bug fixes or enhancements, refer to the Bugzilla numbers associated with this advisory. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes : * the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) * the Linux kernel implementation of the Network File System (NFS) did not properly initialize the file name limit in the nfs_server data structure. This flaw could possibly lead to a denial of service on a client mounting an NFS share.

NASL family Scientific Linux Local Security Checks NASL id SL_20090630_KERNEL_ON_SL4_X.NASL description These updated packages fix the following security issues : - the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) - the Linux kernel implementation of the Network File System (NFS) did not properly initialize the file name limit in the nfs_server data structure. This flaw could possibly lead to a denial of service on a client mounting an NFS share. (CVE-2009-1336, Moderate) - a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service. (CVE-2009-1385, Important) - the Linux kernel Network File System daemon (nfsd) implementation did not drop the CAP_MKNOD capability when handling requests from local, unprivileged users. This flaw could possibly lead to an information leak or privilege escalation. (CVE-2009-1072, Moderate) - Frank Filz reported the NFSv4 client was missing a file permission check for the execute bit in some situations. This could allow local, unprivileged users to run non-executable files on NFSv4 mounted file systems. (CVE-2009-1630, Moderate) - a missing check was found in the hypervisor_callback() function in the Linux kernel provided by the kernel-xen package. This could cause a denial of service of a 32-bit guest if an application running in that guest accesses a certain memory location in the kernel. (CVE-2009-1758, Moderate) - a flaw was found in the AGPGART driver. The agp_generic_alloc_page() and agp_generic_alloc_pages() functions did not zero out the memory pages they allocate, which may later be available to user-space processes. This flaw could possibly lead to an information leak. (CVE-2009-1192, Low) These updated packages also fix the following bugs : - last seen 2020-06-01 modified 2020-06-02 plugin id 60609 published 2012-08-01 reporter This script is Copyright (C) 2012-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/60609 title Scientific Linux Security Update : kernel on SL4.x i386/x86_64 NASL family OracleVM Local Security Checks NASL id ORACLEVM_OVMSA-2009-0009.NASL description The remote OracleVM system is missing necessary patches to address critical security updates : CVE-2008-4307 Race condition in the do_setlk function in fs/nfs/file.c in the Linux kernel before 2.6.26 allows local users to cause a denial of service (crash) via vectors resulting in an interrupted RPC call that leads to a stray FL_POSIX lock, related to improper handling of a race between fcntl and close in the EINTR case. CVE-2009-1337 The exit_notify function in kernel/exit.c in the Linux kernel before 2.6.30-rc1 does not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application. CVE-2009-0834 The audit_syscall_entry function in the Linux kernel 2.6.28.7 and earlier on the x86_64 platform does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls, a related issue to CVE-2009-0342 and CVE-2009-0343. CVE-2009-1336 fs/nfs/client.c in the Linux kernel before 2.6.23 does not properly initialize a certain structure member that stores the maximum NFS filename length, which allows local users to cause a denial of service (OOPS) via a long filename, related to the encode_lookup function. - CVE-2008-4307 -[nfs] remove bogus lock-if-signalled case (Bryn M.
