A vulnerability was detected in Totolink A3002MU 1.0.0-B20230403.1455. This impacts the function sub_44B250 of the file /boafrm/formUploadFile of the component File Upload Handler. The manipulation of the argument filename results in path traversal. The attack can be executed remotely. The exploit is now public and may be used.
AnalysisAI
Path traversal in the Totolink A3002MU router's File Upload Handler (firmware 1.0.0-B20230403.1455) allows remote unauthenticated attackers to write files outside the intended upload directory by manipulating the 'filename' argument to /boafrm/formUploadFile. Publicly available exploit code exists, but there is no confirmed active exploitation (CISA KEV). …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the Totolink A3002MU (firmware 1.0.0-B20230403.1455) web interface endpoint /boafrm/formUploadFile, where the attacker supplies a manipulated 'filename' argument containing directory-traversal sequences to the File Upload Handler (function sub_44B250). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a moderate-severity path traversal (CWE-22) in the Totolink A3002MU router's File Upload Handler, and the available signals point to a real-but-not-urgent issue rather than a top-tier priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch identified at time of analysis; check https://www.totolink.net/ and the VulDB entry https://vuldb.com/vuln/413467 for future firmware updates. … Detailed patch versions, workarounds, and compensating controls in full report. |
