CVE-2020-8800Network attack vector

Authenticated PHP code execution via preference deserialization

Published Feb 13, 2020 · Updated Aug 4, 2024

PHP object injection in SuiteCRM 7.11.11 and earlier allows remote authenticated users to execute arbitrary PHP code via saved preferences. EmailsControllerActionGetFromFields passes attacker-controlled account_signatures and showFolders preference values to unserialize(), instantiating arbitrary objects. A low-privileged account that can modify these values through EmailUIAjax can trigger gadget behavior in the server process.
