Description
A vulnerability was identified in Trendnet TEW-635BRM up to 1.00.03. This affects the function start_httpd of the file /sbin/rc of the component Web Service. Such manipulation of the argument device_name leads to stack-based buffer overflow. The attack can be executed remotely. The exploit is publicly available and might be used. The vendor explains: "We are unable to confirm if the vulnerability exists. This item has been EOL since 2011. We will make an official announcement of possible vulnerabilities, and recommend users to switch devices." This vulnerability only affects products that are no longer supported by the maintainer.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-15480 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-15480 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-15480. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-15480 in your dependencies?
O3 detects CVE-2026-15480 across dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
