Zabbix < 1.8.16 / 2.0.5 / 2.1.0 user.login cnf Parameter Authentication Bypass

medium Nessus Plugin ID 66945

Language:

Synopsis

The remote web application may be affected by an authentication bypass vulnerability.

Description

According to its self-reported version number, the instance of Zabbix listening on the remote host is a version greater than 1.8.1 prior to 1.8.16, or version 2.0.x prior to 2.0.5. It, therefore, could be affected by an authentication bypass flaw in the 'user.login' method. The issue is triggered when LDAP authentication requests passed via the 'cnf' parameter are not properly handled. A remote attacker could override the stored LDAP settings to redirect to authentication.

Note that Nessus has not tested for these issues but has instead relied on the version in the Zabbix login page.

Solution

Update Zabbix to version 1.8.16 / 2.0.5 / 2.1.0 or later.
