CVE-2026-61517: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Netis Systems NX10
Description
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.

Technical Analysis
CVE-2026-61517 is an OS command injection vulnerability in Netis Systems NX10 firmware versions 4.0.1.5808 and 3.0.0.4142. The flaw exists in the ping diagnostic handler where the IpAddr parameter is interpolated directly into a shell command executed via system(). The denylist used to sanitize input blocks spaces, pipes, semicolons, and ampersands but does not block command substitution or alternate field separator expansions, allowing authenticated administrators to execute arbitrary commands as root.
Potential Impact
An authenticated administrator can execute arbitrary shell commands with root privileges on affected Netis NX10 devices. This can lead to full system compromise, unauthorized control, and potential disruption of device operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrative access to trusted users only and avoid using the vulnerable ping diagnostic feature with untrusted input.
