CVE-2020-14933 (CCN-183870)

Assigned:2020-06-20
Published:2020-06-20
Updated:2021-11-30
Summary:** 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). .
