Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Improper Certificate Validation
EUVDB-ID: #VU77752
Risk: Medium
CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-1664
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass client certificate validation.
The vulnerability exists due to improper certificate validation when using X509 Client Certificate Authenticatior with the option "Revalidate Client Certificate". A remote attacker with ability to directly connect to Keycloak (e.g. not via the reverse proxy) can bypass certificate validation and gain unauthorized access to the application.
Successful exploitation of the vulnerability requires that there's a configuration error in KC_SPI_TRUSTSTORE_FILE_FILE, which results in accepting any certificate with the logging information of "Cannot validate client certificate trust: Truststore not available".
