CVE-2022-35620

Vulnerability

D-LINK DIR-818LW A1 router running firmware version DIR818L_FW105b01 contains a remote code execution vulnerability in the function binary.soapcgi_main. The exact nature of the flaw is not fully detailed by the vendor, but it allows an attacker to execute arbitrary code on the device. This affects the DIR-818LW A1 hardware revision specifically with the indicated firmware.

Exploitation

The exploitation vector is not fully disclosed by the vendor, as D-Link typically withholds details that could enable crafting an exploit. However, based on the description, an attacker likely needs network access to the router's management interface. No authentication requirement is specified, suggesting that unauthenticated remote exploitation may be possible.

Impact

Successful exploitation leads to remote code execution on the router, giving the attacker full control over the device. This could allow the attacker to modify device configuration, intercept network traffic, or use the device as a pivot point for further attacks on the network.

Mitigation

D-Link has not released a firmware update for this vulnerability as of the publication date. The vendor's security bulletin [1] does not list a fix, and the device may be end-of-life (EOL). Users should consider replacing the router or, if possible, restrict network access to the management interface and disable remote administration features.
