Description
functions/html_to_text.php in the Chat module before 1.5.2 for activeCollab allows remote authenticated users to execute arbitrary PHP code via the message[message_text] parameter to chat/add_messag, which is not properly handled when executing the preg_replace function with the eval switch.
