Name of the Vulnerable Software and Affected Versions: Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software (affected versions not specified)

Description: The issue is related to multiple vulnerabilities in the web services interface of the affected software, which could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the web services interface. The vulnerabilities are due to insufficient validation of user-supplied input by the web services interface. An attacker could exploit these vulnerabilities by persuading a user of the interface to click a crafted link, potentially allowing the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information. These vulnerabilities affect only specific AnyConnect and WebVPN configurations.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
