Cisco Unified Communications Manager Web-based Management Interface 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 and Unified Communications Manager Session Management Edition (Unified Communication Software) (affected version not known). It has been rated as problematic. Affected by this issue is some unknown functionality of the component Web-based Management Interface. The manipulation with an unknown input leads to a directory traversal vulnerability. Using CWE to declare the problem leads to CWE-23. The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. The impact remains unknown. CVE summarizes:
A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the operating system.
The weakness was disclosed 07/07/2022 as cisco-sa-ucm-file-read-qgjhEc3A. The advisory is available at tools.cisco.com. This vulnerability is handled as CVE-2022-20862 since 11/02/2021. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 07/19/2022). This vulnerability is assigned to T1006 by the MITRE ATT&CK project.
Upgrading eliminates this vulnerability.
