Description

An unauthenticated, remote attacker might utilise a vulnerability in the Cisco Adaptive Security Appliance (ASA) web interface to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) scenario. The ASA may not reload on some software releases, but an attacker could use directory traversal techniques to view important system information without authentication. The vulnerability is caused by the HTTP URL’s input not being properly validated.
