Authenticated command execution via encoded file parameter
Published Jul 5, 2024 · Updated Aug 1, 2024
Deserialization in /log/decodmail.php in D-Link DAR-7000 version 20230922 allows remote authenticated users to execute commands. The endpoint processes an attacker-controlled Base64-encoded file parameter whose decoded pathname contains shell metacharacters and command substitution. A valid PHP session is required, and successful exploitation runs commands with the appliance web service privileges.
