CVE-2016-6463: A vulnerability in the email filtering functionality of Cisco AsyncOS Software for Cisco Email Security App...

A vulnerability in the email filtering functionality of Cisco AsyncOS Software for Cisco Email Security Appliances could allow an unauthenticated, remote attacker to bypass Advanced Malware Protection (AMP) filters that are configured for an affected device. This vulnerability affects all releases prior to the first fixed release of Cisco AsyncOS Software for both virtual and hardware versions of Cisco Email Security Appliances, if the AMP feature is configured to scan incoming email attachments. More Information: CSCuz85823. Known Affected Releases: 10.0.0-082 9.7.0-125 9.7.1-066. Known Fixed Releases: 10.0.0-203 9.7.2-131.

Security readout for executives and security teams

Cisco Email Security Appliances running vulnerable AsyncOS versions could fail to apply AMP malware scanning to incoming attachments. In business terms, a mail gateway meant to block malicious files may let some risky attachments through. Exposure is limited to Cisco Email Security Appliances using affected AsyncOS releases with AMP enabled for incoming attachment scanning. Known affected releases include 9.7.0-125, 9.7.1-066, and 10.0.0-082. Prioritize remediation for internet-facing mail gateways that process business email. The issue can undermine malware filtering, increasing phishing and attachment-borne malware risk even without evidence of active exploitation. Mitigation focus: Upgrade AsyncOS to a Cisco fixed release: 9.7.2-131 or 10.0.0-203.; Confirm Cisco advisory guidance for any later fixed or recommended releases.; Keep AMP attachment scanning enabled after upgrading..
