Cisco ASA Software Multiple Vulnerabilities (cisco-sa-20150408-asa)

high Nessus Plugin ID 82852


The remote device is missing a vendor-supplied security patch.


The remote Cisco Adaptive Security Appliance (ASA) is missing a vendor-supplied security patch and is therefore affected by the following vulnerabilities :

- A flaw exists in the failover ipsec feature due to not properly handling failover communication messages. An unauthenticated attacker, sending crafted UDP packets over the local network to the failover interface, can reconfigure the failover units to gain full control.

- A flaw exists when handling DNS reply packets, which a man-in-the-middle attacker, by triggering outbound DNS queries and then sending crafted responses to these, can exploit to consume excessive memory, leading to a denial of service. (CVE-2015-0676)

- A flaw exists in the XML Parser configuration when handling specially crafted XML messages, which a remote, unauthenticated attacker can use to crash the WebVPN component, resulting in a denial of service condition.
