Cisco Identity Services Engine (cisco-sa-isexss-BS8ctE7U)

medium Nessus Plugin ID 306558

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, Cisco ISE is affected by a vulnerability.

- Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker with administrativewrite privileges to conduct a stored cross-site scripting (XSS) attack or a reflected XSS attack against a user of the web-based management interface of an affected device. These vulnerabilities are due to insufficient sanitization of user-supplied data that is stored in the web page. An attacker could exploit these vulnerabilities by convincing a user of the interface to click a specific link or view an affected web page. The injected script code may be executed in the context of the web-based management interface or allow the attacker to access sensitive browser-based information. (CVE-2026-20132)

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
