Lifecycle Timeline
5DescriptionCVE.org
A vulnerability was identified in TRENDnet TEW-432BRP 3.10B20. This affects the function formWlanSetup of the file /goform/formWlanSetup. The manipulation of the argument enrollee leads to stack-based buffer overflow. The attack may be initiated remotely. The exploit is publicly available and might be used. 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 3.10B20 router allows remote attackers with low privileges to corrupt memory via the enrollee parameter in the formWlanSetup handler at /goform/formWlanSetup. Publicly available exploit code exists, and the vendor has explicitly declined to patch because the device reached end-of-life in 2009. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the device's HTTP administration interface and an authenticated session sufficient to invoke /goform/formWlanSetup (CVSS PR:L), so the attacker must have either valid admin credentials, default/unchanged credentials, a hijacked session, or LAN-side access where the panel is exposed without strong auth. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 4.0 vector AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H scores 7.4 (High), reflecting network reach, low complexity, and full confidentiality/integrity/availability impact on the vulnerable component, but PR:L indicates some authentication or session context is required, which limits drive-by exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has reached the router's web administration interface - for example, a malicious user on the LAN/WLAN, or an external attacker against a unit with WAN-side admin enabled or default credentials - sends a crafted POST to /goform/formWlanSetup with an oversized 'enrollee' value, overwriting the saved return address on the stack. Because the public PoC at github.com/wudipjq/my_vuln demonstrates the crash and offset, weaponization to a working root shell on this mitigation-free MIPS/ARM firmware is well within reach of a moderately skilled attacker. … |
| Remediation | No vendor-released patch identified at time of analysis - TRENDnet has publicly stated it will not produce a fix because the TEW-432BRP has been EOL since 2009, so the only durable remediation is to decommission the device and replace it with a currently supported router. … Detailed patch versions, workarounds, and compensating controls in full report. |
