Cisco Expressway Series Cross-Site Scripting Vulnerability

A cross-site scripting (XSS) vulnerability has been identified in the web-based management interface of Cisco Expressway Series, which includes both Expressway Control (Expressway-C) and Cisco Expressway Edge (Expressway-E) devices. This vulnerability allows an unauthenticated, remote attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. The issue arises because the management interface fails to properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a crafted link.

Impact

Exploitation of this vulnerability could lead to cross-site scripting, allowing attackers to execute scripts in the context of the user's session or access sensitive information from the user's browser.

Remediation

Cisco has released software updates to address this vulnerability. Users are advised to consult the Cisco Security Advisories page for information on fixed releases and upgrade instructions.
