Summary

A security flaw in AsusWRT prior to version 3.0.0.4.384_10007 allows unauthenticated attackers to exploit the do_vpnupload_post function within the vpnupload.cgi file. By sending a specially crafted request, attackers can modify NVRAM settings, including changing the admin password and enabling SSH access, thereby gaining remote administrative control of the affected router.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
