A vulnerability in the WebVPN portal of Cisco Adaptive Security Appliance (ASA) could allow an authenticated, remote attacker to view sensitive information from the affected system. The vulnerability is due to improper input validation in the WebVPN portal. An attacker could exploit this vulnerability by providing a crafted JavaScript file to an authenticated WebVPN user. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit this vulnerability, an attacker must authenticate to a targeted device. This access requirement reduces the likelihood of a successful exploit. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
