CVE-2026-71989: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in MSI Radix AXE6600
CVE-2026-71989 is a critical command injection vulnerability in the MSI Radix AXE6600 router firmware version v781521. It exists in the porTrigger function and can be exploited remotely via the alg function to execute arbitrary OS commands with root privileges. This allows an attacker to fully compromise the affected device without authentication.
AI Analysis
Technical Summary
The MSI Radix AXE6600 router firmware version v781521 contains an OS command injection vulnerability in the porTrigger function. Remote attackers can exploit this flaw through the alg function to execute arbitrary commands on the underlying operating system, gaining root-level access. The vulnerability arises from improper neutralization of special elements in OS commands, enabling command injection without requiring privileges or user interaction. The CVSS 4.0 base score is 9.3, reflecting its critical severity and ease of exploitation over the network.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary OS commands with root privileges on the affected MSI Radix AXE6600 device. This can lead to full device compromise, including control over network traffic, device configuration, and potential pivoting within the network environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Users should monitor MSI's advisories for updates and apply patches promptly once available.
