CVE-2017-12303
A vulnerability in the Advanced Malware Protection (AMP) file filtering feature of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to bypass a configured AMP file filtering rule.
Does this matter?
Lower severity and a low EPSS score (1.64%). Track it; it rarely justifies an emergency change on its own.
