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.

    descriptionThe SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.45 and fixes various bugs and security issues. The following security issues have been fixed : - Timo Warns reported an issue in the Linux implementation for GUID partitions. Users with physical access could gain access to sensitive kernel memory by adding a storage device with a specially crafted corrupted invalid partition table. (CVE-2011-1776) - The second part of this fix was not yet applied to our kernel: arch/x86/kvm/x86.c in the Linux kernel before 2.6.36.2 does not initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via read operations on the /dev/kvm device. (CVE-2010-3881) - The /proc/PID/io interface could be used by local attackers to gain information on other processes like number of password characters typed or similar. (CVE-2011-2495) - A small buffer overflow in the radio driver si4713-i2c was fixed that could potentially used by local attackers to crash the kernel or potentially execute code. (CVE-2011-2700) - A kernel information leak in the comedi driver from kernel to userspace was fixed. (CVE-2011-2909) - In the perf framework software event overflows could deadlock or delete an uninitialized timer. (CVE-2011-2918)

    descriptionThe SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.45 and fixes various bugs and security issues. The following security issues have been fixed : - Timo Warns reported an issue in the Linux implementation for GUID partitions. Users with physical access could gain access to sensitive kernel memory by adding a storage device with a specially crafted corrupted invalid partition table. (CVE-2011-1776) - The second part of this fix was not yet applied to our kernel: arch/x86/kvm/x86.c in the Linux kernel before 2.6.36.2 does not initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via read operations on the /dev/kvm device. (CVE-2010-3881) - The /proc/PID/io interface could be used by local attackers to gain information on other processes like number of password characters typed or similar. (CVE-2011-2495) - A small buffer overflow in the radio driver si4713-i2c was fixed that could potentially used by local attackers to crash the kernel or potentially execute code. (CVE-2011-2700) - A kernel information leak in the comedi driver from kernel to userspace was fixed. (CVE-2011-2909) - In the perf framework software event overflows could deadlock or delete an uninitialized timer. (CVE-2011-2918)
