Raccoon attack in IBM Engineering Workflow Management (EWM)

1) Raccoon attack

EUVDB-ID: #VU46573

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

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

Install update from vendor's website.
