Authenticated command execution via param filter bypass
Published Aug 25, 2022 · Updated Jun 17, 2025
OS command injection in DelL2tpLNSList in H3C GR2200 MiniGR1A0V100R014 allows local users to execute arbitrary commands. DelL2tpLNSList uses snprintf to place the param value into a command passed to system(), while its character filter permits $() command substitution. Reachability requires access to the Web management interface and an authenticated JSESSIONID; successful injection runs commands in the firmware context.
