Attack vector: Network
Complexity: Low
Privileges needed: None
User interaction: None
Impact: Full C/I/A compromise
Weakness: CWE-77, CWE-78

Impact

Unauthenticated remote attackers can execute arbitrary OS commands as root on the router. They only need network access to the web management interface to send a malicious HTTP request.

Root cause

The HNAP CGI handler in /htdocs/cgibin directly passes unsanitized input from the SOAPACTION HTTP header to the system shell function.

Affected systems

D-Link DIR-868L version 2.01b05

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

Fix & remediation

No patched firmware version is listed; replace the end-of-life router or restrict all incoming access to the web management interface and HNAP endpoints via upstream firewalling.
