A vulnerability in the TLS handler of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote malicious user to gain access to sensitive information. This vulnerability is due to improper implementation of countermeasures against a Bleichenbacher attack on a device that uses SSL decryption policies. An attacker could exploit this vulnerability by sending crafted TLS messages to an affected device, which would act as an oracle and allow the malicious user to carry out a chosen-ciphertext attack. A successful exploit could allow the malicious user to perform cryptanalytic operations that may allow decryption of previously captured TLS sessions to the affected device.
