A command injection vulnerability exists in LILIN Digital Video Recorder (DVR) devices prior to firmware version 2.0b6020200207 via the Server field in the NTPUpdate configuration. The web service at /z/zbin/dvrbox fails to properly sanitize input, allowing remote attackers to inject and execute arbitrary commands as root by supplying specially crafted XML data to the DVRPOST interface.

An unauthenticated arbitrary file read exists in LILIN Digital Video Recorder (DVR) devices prior to firmware version 2.0b6020200207 via the /z/zbin/nethtml.cgi endpoint. This vulnerability allows attackers to read sensitive configuration files, such as /zconf/service.xml, which can then be used to facilitate further attacks including command injection. The vulnerability has been exploited in the wild in conjunction with other issues by botnets like FBot and Moobot.

A command injection vulnerability exists in LILIN Digital Video Recorder (DVR) devices prior to firmware version 2.0b6020200207 due to insufficient sanitization of the FTP and NTP Server fields in the service configuration. An attacker with access to the configuration interface can upload a malicious XML file with injected shell commands in these fields. Upon subsequent configuration syncs, these commands are executed with elevated privileges. This vulnerability was exploited in the wild by the Moobot botnets.
