Detailsinfo

A vulnerability was found in Cisco Evolved Programmable Network Manager and Prime Infrastructure (version unknown). It has been classified as problematic. Affected is an unknown function. 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. CVE summarizes:

A vulnerability in the web-based management interface of Cisco Evolved Programmable Network Manager (EPNM) and Cisco Prime Infrastructure could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against users of the interface of an affected system. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious code into specific data fields in 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 this vulnerability, an attacker must have valid administrative credentials.
