  • cisco-sa-ftd-sidns-bypass-3PzA5pOCisco Firepower Threat Defense Software Security Intelligence DNS Feed Bypass Vulnerability2022-04-27csaf · cisco_csafUS

    A vulnerability in the Security Intelligence feed feature of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass the Security Intelligence DNS feed. This vulnerability is due to incorrect feed update processing. An attacker could exploit this vulnerability by sending traffic through an affected device that should be blocked by the affected device. A successful exploit could allow the attacker to bypass device controls and successfully send traffic to devices that are expected to be protected by the affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is part of the April 2022 release of the Cisco ASA, FTD, and FMC Security Advisory Bundled publication. For a complete list of the advisories and links to them, see Cisco Event Response: April 2022 Cisco ASA, FMC, and FTD Software Security Advisory Bundled Publication ["https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-74836"].
