CVE-2025-15471 — TRENDnet TEW-713RE formFSrvX os command injection

A vulnerability was detected in TRENDnet TEW-713RE 1.02. The impacted element is an unknown function of the file /goformX/formFSrvX. The manipulation of the argument SZCMD results in os command injection. It is possible to launch the attack remotely. The exploit is now public and may be used. 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.

Moderate

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 13.7% (30-day exploitation probability)+14
Technical severity (critical)+10
CISA SSVC: exploitation "poc"+5
Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (TRENDnet TEW-713RE, Trendnet Tew-713re Firmware).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
EPSS ahead of 96% of scored CVEs: prioritize it in the patch queue.
Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.
