Raccoon attack against TLS implementation in F5 BIG-IP

1) Raccoon attack

EUVDB-ID: #VU46573

Risk: Medium

CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:U/RC:C]

CVE-ID: CVE-2020-1968

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a timing flaw in the TLS specification. A remote attacker can compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite and eavesdrop on all encrypted communications sent over that TLS connection.

Note: The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
