Name of the Vulnerable Software and Affected Versions Cisco Adaptive Security Appliance (ASA) Software (affected versions not specified)

Description The issue is related to insufficient protection of the web interface structure, allowing for a cross-site scripting (XSS) attack. This attack can be conducted by an unauthenticated, remote attacker against a user of the interface. The vulnerability exists due to the web-based management interface not properly validating user-supplied input. An attacker could exploit this by persuading a user to click a crafted link, potentially allowing the execution of arbitrary script code in the context of the interface or access to sensitive, browser-based information.
