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
DescriptionThe 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.
Update the affected package samba.
