An issue was discovered on Shenzhen Coship WM3300 WiFi Router 5.0.0.55 devices. The password reset functionality of the Wireless SSID doesn't require any type of authentication. By making a POST request to the regx/wireless/wl_security_2G.asp URI, the attacker can change the password of the Wi-FI network.

Detection & IOCsextracted from sources · hover to see the quote

urlregx/wireless/wl_security_2G.asp↗
  • →Detect unauthenticated HTTP POST requests to the vulnerable endpoint `regx/wireless/wl_security_2G.asp` on Coship router devices — no authentication headers or session cookies are required, making any POST to this path suspicious. ↗
  • →Affected firmware versions to fingerprint during asset inventory: Coship RT3052 4.0.0.48, Coship RT3050 4.0.0.40, Coship WM3300 5.0.0.54, Coship WM3300 5.0.0.55, Coship RT7620 10.0.0.49. ↗
  • ·The exploit targets the router's LAN/gateway IP address, meaning the attacker must already have network access (LAN or WLAN) to the device; the attack surface is limited to the local network segment unless the router's admin interface is exposed to the WAN. ↗
  • ·The PoC hardcodes the resulting Wi-Fi password to the string 'password', but any attacker can trivially modify the POST body to set an arbitrary passphrase, so detection should not rely on a specific password value in the request body. ↗
