CVE-2023-4711Network attack vector

Authenticated command execution via unsanitized file parameter

Published Sep 1, 2023 · Updated Aug 2, 2024

OS command injection in D-Link DAR-8000-10 20230819 allows remote authenticated users to execute commands via a crafted file parameter. The /log/decodmail.php handler sends the file parameter to an operating-system command without neutralizing command separators. Reaching the handler requires authenticated network access, and successful injection can read, modify, or interrupt appliance data and services.
