5DescriptionCVE.org
A vulnerability was found in Tenda JD12L 16.03.53.23. This impacts the function fromNatStaticSetting of the file /goform/NatStaticSetting. The manipulation of the argument page results in stack-based buffer overflow. The attack can be executed remotely. The exploit has been made public and could be used.
AnalysisAI
Stack-based buffer overflow in the Tenda JD12L router (firmware 16.03.53.23) lets remote attackers corrupt memory via the 'page' parameter handled by the fromNatStaticSetting function at the /goform/NatStaticSetting endpoint. Publicly available exploit code exists, and the CVSS 4.0 vector (PR:L) indicates an authenticated user on the device's web interface can trigger high confidentiality, integrity and availability impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the router's HTTP management interface and at least low-privileged authentication (CVSS PR:L), then sending a request to the /goform/NatStaticSetting endpoint with a malicious 'page' argument that triggers the fromNatStaticSetting stack overflow. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are partly conflicting and should be weighed carefully. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach the router's web interface and holds low-privilege credentials (or default/guessable ones) sends a crafted HTTP request to /goform/NatStaticSetting with an oversized 'page' parameter, overflowing the stack buffer in fromNatStaticSetting. This can crash the device (denial of service) or, with a reliable payload, achieve code execution on the router. … |
| Remediation | No vendor-released patch is identified at time of analysis; Tenda has not published a fixed firmware version in the available data, so monitor https://www.tenda.com.cn/ for an updated build and apply it once released. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
24 hours: Inventory all Tenda JD12L routers in production, prioritizing firmware 16.03.53.23; verify which devices have web management interfaces accessible from untrusted networks. …
