CVE-2026-33568 · Severity: critical · CVSS 9.1 · Published 2026-10-20

The TOTOLINK X2000R is a budget home router that relies on the boa web server for administration. A flaw in the device's web interface allows an authenticated attacker to inject arbitrary operating system commands through the macstr parameter, potentially gaining complete control over the router. An attacker with valid credentials can execute arbitrary code to compromise the device and any network it protects.

## Technical details

An OS command injection vulnerability exists in the formMapDelDevice function within the boa web server. The macstr parameter extracted from an authenticated HTTP POST request is passed unsanitized via strcpy to a stack buffer, then used in a sprintf call that constructs an iwpriv command passed to system(). An authenticated attacker can inject shell metacharacters in the macstr parameter to execute arbitrary OS commands on the router with the privileges of the boa daemon.
