CVE-2026-71983: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in MSI Radix AXE6600
MSI Radix AXE6600 router firmware version v781521 contains a critical OS command injection vulnerability in the wps.cgi interface. Remote attackers can exploit unsanitized parameters (pin2g, pin5g, pin6g) to execute arbitrary commands with root privileges. This vulnerability allows full control over the affected device without authentication.
AI Analysis
Technical Summary
The MSI Radix AXE6600 router firmware version v781521 has an OS command injection vulnerability in the wps.cgi interface. Specifically, the pin2g, pin5g, and pin6g parameters are not properly sanitized, allowing remote attackers to inject and execute arbitrary OS commands. Successful exploitation grants root-level access on the device, posing a critical security risk. The vulnerability is identified as CVE-2026-71983 with a CVSS 4.0 score of 9.3, indicating high exploitability and impact. No official patch or remediation information is currently available, and no known exploits in the wild have been reported.
Potential Impact
Exploitation of this vulnerability allows remote attackers to execute arbitrary commands on the affected MSI Radix AXE6600 router with root privileges. This can lead to full device compromise, unauthorized control, and potential disruption of network operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the wps.cgi interface and monitor for suspicious activity targeting the pin2g, pin5g, and pin6g parameters.
