1 technique across 1 tactic: Execution

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Requires authentication to the router's web management interface (PR:L). The attacker must have network access to the router's web interface (AV:N). No special configuration needed beyond default settings. The vulnerability is in the formWlSiteSurvey function, which is accessible via the web interface.

Impact

CVSS 4.0 base score is 2.1 (Low) with vector AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N, indicating low impact but network-accessible, low complexity, and low privileges required. However, EPSS score of 3.75% (88th percentile) suggests moderate exploitation probability, and public exploit availability increases risk. The vulnerability is not listed in CISA KEV. The SSVC decision would likely prioritize due to public exploit and automatable nature. The low CVSS score may understate risk because command injection often leads to full device compromise.

Exploit ScenarioDerived

An attacker with low-privileged access to the router's web interface sends a crafted HTTP request to /boafrm/formWlSiteSurvey with a malicious wlanif parameter containing command injection payloads. Public exploit code is available, enabling arbitrary command execution on the device.

Monitor Track and reassess. Why: LOW severity (CVSS 0.1-3.9).

RemediationAI

No vendor-released patch identified at time of analysis. As a workaround, restrict access to the web management interface to trusted networks only, disable remote management if not required, and monitor for suspicious activity. Consider upgrading to a newer firmware version if available from TOTOLINK. Side effects: disabling remote management may reduce convenience for remote administration.
