How severe is CVE-2026-10062?

CVE-2026-10062 has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

Which products are affected by CVE-2026-10062?

Affected package information for CVE-2026-10062 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2026-10062?

No patch has shipped for CVE-2026-10062 yet — track the trendnet tew-432brp firmware advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2026-10062 across my infrastructure?

Inventory every trendnet tew-432brp firmware deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2026-10062 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2026-10062?

O3 detects and blocks CVE-2026-10062 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2026-10062 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-10062 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-10062?

CVE-2026-10062 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 53th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-10062?

CVE-2026-10062 is classified as Buffer Overflow (CWE-119), CWE-121 (CWE-121). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2026-10062?

CVE-2026-10062 affects trendnet tew-432brp firmware (1 version, e.g. 3.10b20). Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2026-10062 published, and has it been updated?

CVE-2026-10062 was published on May 29, 2026 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

A vulnerability was determined in TRENDnet TEW-432BRP 3.10B20. Affected by this vulnerability is the function formSetRoute of the file /goform/formSetRoute. This manipulation of the argument ip/mask/gateway causes stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized. 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.
