Detailsinfo

A vulnerability, which was classified as problematic, was found in Cisco Packaged Contact Center Enterprise and Unified Contact Center Enterprise (unknown version). This affects an unknown code block of the component Web-based Management Interface. The manipulation with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. The summary by CVE is:

Multiple vulnerabilities in the web-based management interface of Cisco Packaged Contact Center Enterprise (Packaged CCE) and Cisco Unified Contact Center Enterprise (Unified CCE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.  These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by injecting malicious code into specific pages of the interface. 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. To exploit these vulnerabilities, the attacker must have valid administrative credentials.
