Technical Analysis

The vulnerability in Zabbix's frontend host search permits filtering by hidden fields such as stored IPMI and PSK credentials. This flaw enables users with read access to iteratively guess credentials and confirm their validity based on search outcomes, thereby exposing sensitive authentication data.

Potential Impact

An attacker with read access to the Zabbix frontend can uncover stored IPMI and PSK credentials by guessing and verifying them through the host search filter. This exposure of sensitive credentials could lead to unauthorized access to management interfaces or other protected resources.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict read access to trusted users only and monitor for suspicious activity related to credential guessing attempts.
