Cisco Unified Communications Manager Database User Privilege absolute 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 classified as critical has been found in Cisco Unified Communications Manager, Unified Communications Manager Session Management Edition and Unified Communications Manager IM & Presence Service (Unified Communication Software) (the affected version unknown). This affects an unknown part of the component Database User Privilege Handler. The manipulation with an unknown input leads to a absolute path traversal vulnerability. CWE is classifying the issue as CWE-36. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" that can resolve to a location that is outside of that directory. This is going to have an impact on confidentiality. The summary by CVE is:

A vulnerability in the database user privileges of Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device. This vulnerability is due to insufficient file permission restrictions. An attacker could exploit this vulnerability by sending a crafted command from the API to the application. A successful exploit could allow the attacker to read arbitrary files on the underlying operating system of the affected device. The attacker would need valid user credentials to exploit this vulnerability.

The weakness was presented 07/07/2022 as cisco-sa-cucm-imp-afr-YBFLNyzd. It is possible to read the advisory at tools.cisco.com.
