"Multiple vulnerabilities in the WebVPN service of Cisco Adaptive
Security Appliance (ASA) Software and Cisco Firepower Threat Defense
(FTD) Software could allow an authenticated, remote attacker to
conduct a cross-site scripting (XSS) attack against a user of the
WebVPN portal of an affected device. The vulnerabilities exist because
the software insufficiently validates user-supplied input on an
affected device. An attacker could exploit these vulnerabilities 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. An attacker would need
administrator privileges on the device to exploit these
vulnerabilities.
