Cisco Intrusion Prevention System MainApp Denial of Service Vulnerability

Related Vulnerabilities: CVE-2014-3402  

A vulnerability in the web framework of Cisco Intrusion Prevention System (IPS) Software could allow an authenticated, remote attacker to cause MainApp to hang intermittently because the authentication manager process creates a denial of service (DoS) condition. The vulnerability is due to improper handling of user tokens. An attacker could exploit this vulnerability by sending a crafted connection request to the Cisco IPS management interface. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit this vulnerability, an attacker must have authenticated access to the targeted system. This access requirement may reduce 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.
