Detailsinfo

A vulnerability, which was classified as critical, was found in Cisco TelePresence Conductor, Expressway Series and TelePresence Video Communication Server up to XC4.3.3 (Unified Communication Software). Affected is an unknown code of the component Web Interface. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
