Customers are advised to migrate to a supported release that includes the fix for this vulnerability.\r\n\r\n2. The First Fixed Release for the 6.6.0 code train was 6.6.3; however, due to upgrade issues associated with CSCvx86231 [\"https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx86231\"] the recommended release is 6.6.4.\r\n\r\nTo upgrade to a fixed release of Cisco FTD Software, do one of the following:\r\n\r\nFor devices that are managed by using Cisco Firepower Management Center (FMC), use the FMC interface to install the upgrade. After installation is complete, reapply the access control policy.\r\nFor devices that are managed by using Cisco Firepower Device Manager (FDM), use the FDM interface to install the upgrade.

This vulnerability is due to the insufficient management of available filesystem resources. An attacker could exploit this vulnerability by uploading files to the device and exhausting available filesystem resources. A successful exploit could allow the attacker to cause database errors and cause the device to become unresponsive to web-based management. Manual intervention is required to free filesystem resources and return the device to an operational state."
