A vulnerability was found in Cisco Unified Communications Manager and Unified Communications Manager Session Management Edition (Unified Communication Software) (affected version unknown). It has been classified as critical. This affects an unknown functionality of the component Web-based Management Interface. 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 integrity, and availability. The summary by CVE is:
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 delete arbitrary files from an affected system. This vulnerability exists because the affected software does not properly validate HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected software. A successful exploit could allow the attacker to delete arbitrary files from the affected system.
The weakness was published 08/10/2022 as cisco-sa-cucm-file-delete-N2VPmOnE. The advisory is shared at tools.cisco.com. This vulnerability is uniquely identified as CVE-2022-20816 since 11/02/2021.
