Lifecycle Timeline
2DescriptionCVE.org
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface.
This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability 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 this vulnerability, the attacker must have valid administrative credentials.
AnalysisAI
Stored XSS in Cisco ISE's web management interface allows authenticated administrators to inject malicious scripts that execute in other users' browsers, potentially compromising sensitive information or hijacking administrative sessions. Exploitation requires valid admin credentials and user interaction, making it suitable for insider threats or compromised accounts. No patch is currently available.
