What is CVE-2025-34132?

A command injection vulnerability affects LILIN Digital Video Recorder (DVR) devices before firmware version 2.0b60_20200207. This vulnerability exists due to inadequate input sanitization in the Server field of the NTPUpdate configuration. Attackers can exploit this flaw by sending specially crafted XML data to the DVRPOST interface, enabling them to execute arbitrary commands with root privileges. The compromised web service at /z/zbin/dvr_box does not sufficiently validate input, resulting in significant security risks for users of these DVR devices.
