A vulnerability, which was classified as problematic, was found in Cisco Unified Communications Manager and Unified Communications Manager Session Management Edition (Unified Communication Software) (the affected version unknown). This affects some unknown processing of the component Web-based Management Interface. The manipulation with an unknown input leads to a cross site request forgery vulnerability. CWE is classifying the issue as CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. This is going to have an impact on integrity. An attacker might be able force legitimate users to initiate unwanted actions within the web application. The summary by CVE is:

A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM) Software and Cisco Unified CM Session Management Edition (SME) Software could allow an authenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected device. This vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user.
