Rar 4.x/5.x Unpack 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.

Detailsinfo

A vulnerability was found in Rar 4.x/5.x. It has been classified as problematic. This affects an unknown code of the component Unpack Handler. The manipulation with an unknown input 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, integrity, and availability. The summary by CVE is:

Directory Traversal exists in RAR 4.x and 5.x because an unpack operation follows any symlinks, including symlinks contained in the archive. This allows remote attackers to write to arbitrary files via a crafted archive.

The bug was discovered 12/29/2014. The weakness was released 06/04/2017 (Website). It is possible to read the advisory at bugs.debian.org. This vulnerability is uniquely identified as CVE-2014-9983. Attacking locally is a requirement. A authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.
