CVE-2023-26802Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized CGI parameters

Published Mar 26, 2023 · Updated May 5, 2025

Command injection in Digital China Networks DCBI-Netlog-LAB 1.0 allows remote attackers to execute arbitrary commands without authentication. The /cgi-bin/network_config/nsg_masq.cgi endpoint interprets shell metacharacters in seven request fields, while a traversal session value bypasses authentication. No credentials or user interaction are required, and successful requests can read or alter data and interrupt the appliance.
