Summary

A vulnerability in Advanced Malware Protection (AMP) for Cisco Email Security Appliances (ESA) and Web Security Appliances (WSA) could allow an unauthenticated, remote attacker to cause a partial denial of service (DoS) condition due to the AMP process unexpectedly restarting. The vulnerability is due to improper validation of a Java Archive (JAR) file scanned when AMP is configured. An attacker could exploit this vulnerability by crafting a JAR file, and attaching this JAR file to an email that is then sent through the affected device. An exploit could allow the attacker to cause the Cisco ESA and WSA AMP process to unexpectedly restart due to the malformed JAR file. Cisco has released software updates that address this vulnerability. Workarounds that address this vulnerability are not available.
