CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as problematic, was found in Debian Linux 3.1 (Operating System). This affects an unknown function of the component cfengine. The manipulation with an unknown input leads to a symlink vulnerability. CWE is classifying the issue as CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. This is going to have an impact on integrity. The summary by CVE is:

cfengine 1.6.5 and 2.1.16 allows local users to overwrite arbitrary files via a symlink attack on temporary files used by vicf.in, a different vulnerability than CVE-2005-3137.

The bug was discovered 10/03/2005. The weakness was released 10/05/2005 by Javier Fernandez-Sanguino Pena (Website). The advisory is shared at debian.org. This vulnerability is uniquely identified as CVE-2005-2960 since 09/19/2005. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 20043 (Mandrake Linux Security Advisory : cfengine (MDKSA-2005:184)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l.
