    cisco-sa-ftd-acl-bypass-8p6vFvwSource published Source updated

    This bulletin covers 2 CVEs. The products, versions, score and guidance below describe the bulletin; check its source for applicability to this specific CVE.

    Multiple vulnerabilities in the access control list (ACL) Object Group Search (OGS) implementation of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass configured access controls.

An attacker could exploit these vulnerabilities by sending traffic that should be blocked through the device. A successful exploit could allow the attacker to bypass access controls and reach devices in protected networks. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. This advisory…
