FreeBSD up to 6.0 SMBFS path traversal

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.

The affected component should be upgraded.

Detailsinfo

A vulnerability, which was classified as critical, was found in FreeBSD up to 6.0 (Operating System). This affects an unknown part of the component SMBFS. The manipulation with the input value ..\ leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

Directory traversal vulnerability in smbfs smbfs on FreeBSD 4.10 up to 6.1 allows local users to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences. NOTE: this is similar to CVE-2006-1864, but this is a different implementation of smbfs, so it has a different CVE identifier.
