CVE-2020-14933: High severity squirrelmail vulnerability

Published Jun 20, 2020

Updated

DISPUTED compose.php in SquirrelMail 1.4.22 calls unserialize for the $attachments value, which originates from an HTTP POST request. NOTE: the vendor disputes this because these two conditions for PHP object injection are not satisfied: existence of a PHP magic method (such as wakeup or destruct), and any attack-relevant classes must be declared before unserialize is called (or must be autoloaded). .
