Lifecycle Timeline
2Description
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.
Analysis
Stored XSS in Cisco Prime Infrastructure and EPNM web management interfaces allows authenticated administrators with high privileges to inject malicious scripts that execute in other users' browsers, potentially enabling session hijacking or credential theft. The vulnerability stems from insufficient input validation in specific data fields and requires valid admin credentials to exploit. …
