MITRE ATT&CK
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 administrative access to the router's web interface (PR:H). The attacker must be able to reach the /boa/formWSC endpoint over the network (AV:N). No user interaction is needed (UI:N). The vulnerability is present in the default configuration of firmware version 3.4.0-B20190525. |
| Impact | CVSS 4.0 base score is 2.0 (Low) with vector AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N, indicating high privileges required but low impact. However, the EPSS score of 1.65% (82nd percentile) suggests moderate exploitation probability. Public exploit code exists, but no CISA KEV listing. The high privilege requirement (PR:H) significantly reduces real-world risk, as an attacker would need administrative access to the router's web interface. The CVSS score may understate the potential impact if an attacker can chain this with other vulnerabilities to escalate privileges. |
| Exploit ScenarioDerived | An attacker with administrative credentials to the TOTOLINK N150RT web interface sends a crafted HTTP request to /boa/formWSC with a malicious targetAPSsid parameter containing command injection payloads. This results in arbitrary command execution on the router with root privileges, allowing the attacker to modify settings, exfiltrate data, or use the device as a pivot point. |

RemediationAI
No vendor-released patch identified at time of analysis. As a workaround, restrict access to the router's web interface to trusted networks only, disable remote management if not required, and monitor logs for suspicious activity. Consider replacing the device if no firmware update becomes available.
