Lifecycle Timeline
5DescriptionCVE.org
A vulnerability was determined in TRENDnet TEW-432BRP 3.10B20. Affected by this vulnerability is the function formSetRoute of the file /goform/formSetRoute. This manipulation of the argument ip/mask/gateway causes stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized. The vendor explains: "This product has been EOL for 15 years (since 2009). As the item has been EOL for such a long time, we are not able to replicate or fix any vulnerabilities." This vulnerability only affects products that are no longer supported by the maintainer.
AnalysisAI
Stack-based buffer overflow in TRENDnet TEW-432BRP router firmware 3.10B20 allows authenticated remote attackers to corrupt memory by sending crafted ip, mask, or gateway parameters to the formSetRoute handler at /goform/formSetRoute, potentially achieving arbitrary code execution on the device. Publicly available exploit code exists (disclosed via VulDB and a GitHub PoC), and because the product has been end-of-life since 2009 the vendor has explicitly declined to issue a fix. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires authenticated access (CVSS PR:L) to the TRENDnet TEW-432BRP web administration interface and network reachability to the /goform/formSetRoute endpoint, specifically the ability to submit the formSetRoute form with attacker-controlled ip, mask, and gateway parameters. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 4.0 scores this 7.4 with vector AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H, signaling network-reachable, low-complexity exploitation that requires low privileges (an authenticated session on the router's web UI) and yields high confidentiality, integrity, and availability impact on the device itself with no scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained admin credentials to the router's web interface - through default-credential reuse, phishing, or LAN-side access - sends a crafted HTTP POST to /goform/formSetRoute with an oversized ip, mask, or gateway value, overflowing a stack buffer in formSetRoute and overwriting the return address to redirect execution. Because legacy SOHO firmware typically lacks ASLR and non-executable stacks, the attacker can stage shellcode for the router's MIPS architecture and gain persistent control of the gateway, pivoting to intercept or redirect all LAN traffic. … |
| Remediation | No vendor-released patch identified at time of analysis, and none will be issued because the device has been EOL since 2009. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: conduct network inventory scan to identify any TRENDnet TEW-432BRP units in production and document owner/location of each device. …
