CRITICAL KEV NUCLEIZabbix 5.4.0-5.4.7 - Unauthenticated Authentication Bypass via SAML Session Spoofing
Title source: llmExploitation Summary
CVE-2022-23131 is actively exploited and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, added February 22, 2022. EIP tracks 21 public exploits from researchers including Mr-xn, jweny, L0ading-x. A Nuclei detection template is also available.
AI-analyzed exploit summary This PoC exploits CVE-2022-23131, an authentication bypass vulnerability in Zabbix's SAML SSO implementation. It manipulates the `zbx_session` cookie to forge a session with arbitrary user credentials, bypassing authentication.
Description
In the case of instances where the SAML SSO authentication is enabled (non-default), session data can be modified by a malicious actor, because a user login stored in the session was not verified. Malicious unauthenticated actor may exploit this issue to escalate privileges and gain admin access to Zabbix Frontend. To perform the attack, SAML authentication is required to be enabled and the actor has to know the username of Zabbix user (or use the guest account, which is disabled by default).
