Cisco Unified Communications Manager up to 5.1%282%29 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.

A vulnerability was found in Cisco Unified Communications Manager up to 5.1%282%29 (Unified Communication Software). It has been classified as critical. This affects an unknown functionality. 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. The summary by CVE is:

Directory traversal vulnerability in Cisco Unified Communications Manager (CUCM) 5.x and 6.x before 6.1(5)SU2, 7.x before 7.1(5b)SU2, and 8.x before 8.0(3), and Cisco Unified Contact Center Express (aka Unified CCX or UCCX) and Cisco Unified IP Interactive Voice Response (Unified IP-IVR) before 6.0(1)SR1ES8, 7.0(x) before 7.0(2)ES1, 8.0(x) through 8.0(2)SU3, and 8.5(x) before 8.5(1)SU2, allows remote attackers to read arbitrary files via a crafted URL, aka Bug IDs CSCth09343 and CSCts44049.
