Cisco ASA Cavium SDK TLS Incorrect Padding Acceptance Plaintext Disclosure (CSCuu93339)

low Nessus Plugin ID 91426

Language:

Synopsis

The remote device is affected by an information disclosure vulnerability.

Description

The remote Cisco Adaptive Security Appliance (ASA) is missing a vendor-supplied security patch. It is, therefore, affected by a flaw in the TLS 1.x implementation in the Cavium SDK due to a failure to check the first byte of the padding bytes. A man-in-the-middle attacker can exploit this, by sending specially crafted requests to the server, to induce requests that allow determining the plaintext chunks of data. This vulnerability is a variant of the POODLE attack.

Solution

Apply the relevant patch referenced in bug ID CSCuu93339, or contact the vendor.
