Technical details

The vulnerability is a command injection flaw in the DMZ function of MSI Radix AXE6600 firmware version v781521. The affected component fails to properly validate or sanitize user input before passing it to a system command execution context, allowing an attacker to inject arbitrary shell commands. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction. A successful exploit grants the attacker root-level code execution on the router, enabling complete device compromise, malware installation, and potential pivot attacks into the network. Patches or fixed firmware versions are not yet confirmed to be available based on available public information.
