CVE-2026-10063: Stack-based Buffer Overflow in TRENDnet TEW-432BRP
A vulnerability was identified in TRENDnet TEW-432BRP 3.10B20. Affected by this issue is the function formWPS of the file /goform/formWPS. Such manipulation of the argument peerPin leads to stack-based buffer overflow. The attack may be performed from remote. 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.
AI Analysis
Technical Summary
This vulnerability affects the TRENDnet TEW-432BRP router running firmware version 3.10B20. The issue is a stack-based buffer overflow triggered by manipulating the peerPin argument in the formWPS function within the /goform/formWPS endpoint. The vulnerability can be exploited remotely without user interaction or privileges. Due to the product's end-of-life status since 2009, the vendor does not provide patches or fixes and cannot reproduce the issue. The CVSS 4.0 score is 8.7, indicating high severity with network attack vector, low attack complexity, no privileges required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation of this vulnerability can lead to remote code execution or denial of service on affected devices. The high CVSS score reflects the potential for significant impact on device operation and network security. However, the affected product is no longer supported or maintained by the vendor, limiting official remediation options.
Mitigation Recommendations
No official fix or patch is available due to the product being end-of-life since 2009. Users should consider replacing the affected TRENDnet TEW-432BRP devices with supported hardware to mitigate risk. Network-level protections such as firewall rules to restrict access to the device's management interface may reduce exposure. Monitor for any unusual activity related to this device, but note that no active exploitation is currently known.
