**Name of the Vulnerable Software and Affected Versions** Zabbix Frontend (affected versions not specified) **Description** The issue is related to the incorrect implementation of IP address checking in Zabbix Frontend, which allows an attacker to bypass protection and access the instance using an IP address not listed in the defined range. This could lead to unauthorized access to confidential data, disruption of data integrity, and potential denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
