CVE-2026-15483: Buffer Overflow in TRENDnet TEW-821DAP
A security vulnerability has been detected in TRENDnet TEW-821DAP 1.12B01. Impacted is the function sub_41EC14 of the file /goform/tools_nslookup of the component ssi. The manipulation of the argument nslookup_target leads to buffer overflow. It is possible to initiate the attack remotely. The vendor explains: "We are unable to confirm the existence of the vulnerabilities for (...) TEW-821DAP (v1.0R) as these items have been EOL. " This vulnerability only affects products that are no longer supported by the maintainer.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the TRENDnet TEW-821DAP device firmware version 1.12B01. The issue is located in the function sub_41EC14 of the /goform/tools_nslookup component, where improper handling of the nslookup_target argument allows a remote attacker to cause a buffer overflow. The vendor has stated that the affected product is no longer supported (EOL), and they cannot confirm the vulnerability for other versions. No official fix or patch has been provided.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker to cause a buffer overflow, potentially leading to denial of service or arbitrary code execution on the affected device. Given the high CVSS score (8.7) and the remote attack vector with no user interaction required, the impact is significant. However, the affected product is end-of-life and unsupported, which limits vendor response and official remediation options.
Mitigation Recommendations
No official patch or remediation is available from the vendor due to the product being end-of-life. Users should consider discontinuing use of the affected device or isolating it from untrusted networks to reduce exposure. Patch status is not yet confirmed — check the vendor advisory for any updates or alternative mitigations if available.
