A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks 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.
The CVSS score of this vulnerability is 4.8, indicating a medium severity level, which means organizations should address it in their priority patch cycle.
Currently, there are no known public exploits or proofs of concept (PoCs) available for this vulnerability. However, given its nature, organizations should remain vigilant and monitor for any changes in the threat landscape.
Organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability is classified under CWE-80, which pertains to improper neutralization of input during web page generation ('Cross-site Scripting').
The affected versions include Cisco Identity Services Engine versions prior to 3.2, as well as 3.2.0 and 3.3.0 with specific patches.
The publication date of this vulnerability is January 15, 2026.
Technical Analysis
The root cause of this vulnerability lies in the web-based management interface's insufficient input validation, allowing malicious scripts to be injected and executed.
The attack vector is network-based, requiring the attacker to have administrative privileges to exploit it. The attack complexity is considered low, with user interaction required to trigger the exploit.
The confidentiality and integrity impacts are both rated as low, while the availability impact is none.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information, leading to data breaches or further exploits. Given that the vulnerability requires administrative credentials, the attack surface is somewhat limited, but organizations should not underestimate the risk.
With a CVSS score of 4.8, this vulnerability is classified as medium severity, necessitating a structured response. Organizations should schedule remediation within their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
