CVE-2025-20179: Cisco Expressway Series Cross-Site Scripting Vulnerability
Description
A vulnerability in the web-based management interface of Cisco Expressway Series could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. 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.
Note: Cisco Expressway Series refers to Cisco Expressway Control (Expressway-C) devices and Cisco Expressway Edge (Expressway-E) devices.
