CVE-2026-61517: OS command injection vulnerability

Netis NX10 firmware V4.0.1.5808 and V3.0.0.4142 contain an OS command injection vulnerability in the ping diagnostic handler that allows authenticated administrators to execute arbitrary shell commands as root by injecting into the IpAddr parameter. The parameter is interpolated directly into a shell command executed through system() with an incomplete denylist that only blocks spaces, pipes, semicolons, and ampersands, leaving command substitution and alternate field separator expansion available for exploitation.
