Remote ACL Bypass via Object Groups in Cisco FMC
CVE-2024-20361 Published on May 22, 2024

A vulnerability in the Object Groups for Access Control Lists (ACLs) feature of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to bypass configured access controls on managed devices that are running Cisco Firepower Threat Defense (FTD) Software. This vulnerability is due to the incorrect deployment of the Object Groups for ACLs feature from Cisco FMC Software to managed FTD devices in high-availability setups. After an affected device is rebooted following Object Groups for ACLs deployment, an attacker can exploit this vulnerability by sending traffic through the affected device. A successful exploit could allow the attacker to bypass configured access controls and successfully send traffic to devices that are expected to be protected by the affected device.
