Security Bulletin

This security bulletin contains one high risk vulnerability.

1) Use of a broken or risky cryptographic algorithm

EUVDB-ID: #VU70384

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-45141

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication.

The vulnerability exists due to an error that allows an attacker to force the server so issue an rc4-hmac ticket encrypted tickets despite the target server supporting better encryption (eg aes256-cts-hmac-sha1-96). A remote attacker can perform an offline attack against the ticket encrypted with rc4-hmac and login as a privileged user.

Mitigation

Install updates from vendor's repository.
