AI Analysis

Impact

The vulnerability is located in the WifiBasic function of /cgi-bin/wireless.cgi on the Wavlink NU516U1 router firmware 240425. Manipulation of the AuthMethod or EncrypType parameters allows an attacker to inject arbitrary operating‑system commands, enabling full remote code execution. An attacker who succeeds can read, modify, or delete data, tamper with the system, or launch further attacks, thereby compromising confidentiality, integrity, and availability of the device.

Affected Systems

Wavlink NU516U1, firmware version 240425.

Risk and Exploitability

The CVSS score of 5.3 indicates medium severity. EPSS information is not available, so the current exploitation probability cannot be quantified; however, the vulnerability is publicly known and can be exploited remotely through the router’s web interface. The vulnerability is not yet catalogued in CISA’s KEV list. The most likely attack vector is a remote attacker sending crafted HTTP requests to the wireless.cgi endpoint from outside the local network.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the router firmware to the latest release that includes a fix for the WifiBasic command injection.
  • If a firmware update is unavailable, disable remote management of wireless settings or block HTTP access to the /cgi-bin/wireless.cgi endpoint entirely.
  • Configure firewall or access control rules to restrict inbound traffic to the router’s web interface so that only trusted networks can reach the vulnerable CGI script.
