        "text": "A vulnerability in the file policy feature that is used to inspect encrypted archive files of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass a configured file policy to block an encrypted archive file.\r\n\r\nThis vulnerability exists because of a logic error when a specific class of encrypted archive files is inspected. An attacker could exploit this vulnerability by sending a crafted, encrypted archive file through the affected device. A successful exploit could allow the attacker to send an encrypted archive file, which could contain malware and should have been blocked and dropped at the Cisco FTD device.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\n\r\n\r\nThis advisory is part of the May 2024 release of the Cisco ASA, FMC, and FTD Software Security Advisory Bundled Publication.

To determine whether the file policy is configured to block encrypted archive files on a Cisco FMC device, use the following steps:\r\n\r\nFrom the configuration screen, choose Policies \u003e Access Control \u003e Malware \u0026 File.\r\nTo view archive file inspection options, choose Advanced Settings in the file policy editor.\r\nLook at the Block Encrypted Archives check box. If it is checked, the device is considered vulnerable.\r\n\r\nFor additional information about using file policies to block malware, see File Policies and File Rules [\"https://www.cisco.com/c/en/us/td/docs/security/secure-firewall/management-center/device-config/730/management-center-device-config-73/network-malware-protection.html?bookSearch=true#ID-2193-00000296\"].",

If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.\r\n      Cisco ASA, FMC, and FTD Software\r\nTo help customers determine their exposure to vulnerabilities in Cisco ASA, FMC, and FTD Software, Cisco provides the Cisco Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"]. This tool identifies any Cisco security advisories that impact a specific software release and the earliest release that fixes the vulnerabilities that are described in each advisory (\u201cFirst Fixed\u201d). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities that are described in all the advisories that the Software Checker identifies (\u201cCombined First Fixed\u201d).\r\n\r\nTo use the tool, go to the Cisco Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"] page and follow the instructions. Alternatively, use the following form to search for vulnerabilities that affect a specific software release. To use the form, follow these steps:\r\n\r\nChoose which advisories the tool will search\u2014all advisories, only advisories with a Critical or High Security Impact Rating (SIR) [\"https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#asr\"], or only this advisory.\r\nChoose the appropriate software.\r\nChoose the appropriate platform.\r\nEnter a release number\u2014for example, 9.16.2.11 for Cisco ASA Software or 6.6.7 for Cisco FTD Software.\r\nClick Check.\r\n      Only this advisory  All Critical and High advisories  All advisories    Cisco ASA Software  Cisco FMC Software  Cisco FTD Software    Any Platform  3000 Series Industrial Security Appliances (ISA)  ASA 5500-X Series Firewalls  ASA Service Module  Adaptive Security Virtual Appliance (ASAv)  Firepower 1000 Series  Firepower 2100 Series  Firepower 4100 Series  Firepower 9000 Series  Firepower NGFW Virtual  Secure Firewall 3100 Series  Firepower Management Center Appliances\r\n\r\n\r\n\r\n\r\nFor instructions on upgrading an FTD device, see Cisco Firepower Management Center Upgrade Guide [\"https://www.cisco.com/c/en/us/td/docs/security/firepower/upgrade/fpmc-upgrade-guide/getting_started.html\"].\r\n\r\n   Additional Resources\r\nFor help determining the best Cisco ASA, FTD, or FMC Software release, see the following Recommended Releases documents.
