Technical details
A SQL injection vulnerability exists in Cacti's 'managers.php' component due to improper handling of deserialized data. The application uses 'cacti_unserialize()' on the 'selected_graphs_array' parameter; while this function disables class instantiation to prevent PHP Object Injection, it still allows the creation of arbitrary string arrays. These array values are subsequently passed to 'implode()' and concatenated directly into a DELETE SQL statement without integer validation or parameterization. An attacker with SNMP agent management permissions can exploit this to execute arbitrary SQL commands. The issue is resolved in version 1.2.31 by applying 'array_map' with 'intval' to ensure all inputs are treated as integers.
