CVE-2023-34275

Root command execution via unvalidated NTP server input

Published May 3, 2024 · Updated Aug 2, 2024

Command injection in D-Link DIR-2150 1.05B01 and earlier allows remote authenticated users to execute arbitrary code as root via its SOAP API. The SetNTPServerSettings SOAP action passes a user-supplied string to a system call without properly validating it. The interface listens on TCP port 80 by default, requires authentication that the existing mechanism can bypass, and limits reachability to adjacent networks.
