Security Bulletin
This security bulletin contains one medium risk vulnerability.
1) Improper Authentication
EUVDB-ID: #VU53692
Risk: Medium
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-20288
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in authentication flow related to CEPHX_GET_AUTH_SESSION_KEY requests. The application does not check other_keys and allows key reuse. A remote attacker who can request a global_id can exploit the ability of any user to request a global_id previously associated with another user, as ceph does not force the reuse of old keys to generate new ones.
MitigationUpdate the affected package ceph to the latest version.
