F5 Networks BIG-IP : OpenSSL vulnerability (SOL16135)

Medium Nessus Plugin ID 81391

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The ssl3_get_cert_verify function in s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman (DH) certificate without requiring a CertificateVerify message, which allows remote attackers to obtain access without knowledge of a private key via crafted TLS Handshake Protocol traffic to a server that recognizes a Certification Authority with DH support.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL16135.
