Title
Netis NX10 OS Command Injection via Ping Diagnostic Handler
Summary
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.
Severity
CWE
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
