A vulnerability was found in Cisco IOS XE and Unified Communications Manager IM and Presence Service (the affected version is unknown). It has been declared as critical. Affected by this vulnerability is an unknown code of the component Web-based Interface. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-23. The product 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability in the web-based interface of Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against an authenticated user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading an authenticated user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.

It is possible to read the advisory at sec.cloudapps.cisco.com. This vulnerability is known as CVE-2024-20310 since 11/08/2023. The exploitation appears to be easy.
