Vulnerabilities

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.

A security vulnerability has been detected in TRENDnet TEW-821DAP 1.12B01. Impacted is the function auto_update_firmware of the component Firmware Udpate. The manipulation of the argument str leads to buffer overflow. The attack may be initiated remotely. The vendor explains: "That firmware version will only work on our hardware version v1.xR. We have already EOL that product 8 years ago and are no longer selling". This vulnerability only affects products that are no longer supported by the maintainer.

A security flaw has been discovered in Trendnet TEW-657BRM 1.00.1. The impacted element is the function update_pcdb of the file /setup.cgi. The manipulation of the argument mac_pc_dba results in stack-based buffer overflow. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks. The vendor confirms, that "[t]he product in question (...) has been discontinued and end of life since June 23, 2011, that is more than 14 years ago. We no longer provide support for this product, so we are not able to confirm the vulnerabilities. We will make an announcement on our website's product support page and notify customers who registered their products with us." This vulnerability only affects products that are no longer supported by the maintainer.

A vulnerability was identified in TRENDnet TEW-713RE up to 1.02. The impacted element is an unknown function of the file /goform/setSysAdm. The manipulation of the argument admuser leads to command injection. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2025-15472 is an operating system command injection flaw in the httpd service of the TRENDnet TEW-811DRU router, located in the setDeviceURL function reached through the uapply.cgi endpoint. An attacker triggers it by submitting a crafted DeviceURL parameter to the router's web interface, and per the CVSS 4.0 vector (PR:H) the attack requires privileges at the administrator level, so it presumes valid access to the management interface. Successful exploitation yields remote command execution on the device with high impact to confidentiality, integrity, and availability, effectively giving the attacker control of the router. Only firmware version 1.0.2.0 is named in the disclosure, the vendor was contacted early but did not respond, and no fixed release is documented. A public proof of concept exists, the EPSS score of 22.6% (98th percentile) indicates a meaningful likelihood of exploitation within 30 days, but the flaw is not in CISA KEV and no confirmed in-the-wild exploitation is reported.

Do: Because the vendor reportedly did not respond and no fixed firmware is documented, owners should verify their TEW-811DRU firmware version and ensure the router's web management interface is not reachable from the WAN (disable remote administration). If remote management is required, restrict access to trusted source addresses or tunnel it via VPN, and monitor TRENDnet support channels for an updated firmware release. Review the published proof of concept to confirm whether the DeviceURL handling in uapply.cgi is reachable in your deployment.

The vendor confirms: "The product in question TEW-731RE for CVE-2025-15471 has been discontinued and end of life since October 23, 2020. We no longer provide support for this product, so we are not able to confirm the vulnerabilities. We will make an announcement on the website product support page and notify customers who registered their products with us." This vulnerability only affects products that are no longer supported by the maintainer.
