Summary

CVE-2025-15139 is a low-severity Injection (CWE-74) vulnerability in Trendnet Tew-822Dre Firmware. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2025-15139 is a command injection vulnerability in the TRENDnet TEW-822DRE AC1200 Dual Band Wireless Router running firmware versions 1.00B21 or 1.01B06. The flaw resides in the function sub_43ACF4 within the /boafrm/formWsc file, where the peerPin argument is improperly handled, allowing attackers to inject arbitrary commands. Associated with CWEs-74 (injection) and CWE-77 (command injection), it carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), indicating medium severity.

The vulnerability enables remote exploitation by attackers who possess low privileges (PR:L), such as authenticated users on the device. By manipulating the peerPin parameter during interactions with the WSC (Wi-Fi Protected Setup) form, an attacker can execute arbitrary commands on the underlying system, potentially leading to limited impacts on confidentiality, integrity, and availability as per the CVSS metrics.

Advisories from VulDB and the disclosure on Notion.site note that the exploit has been publicly released and may be actively used, but the vendor was contacted early without any response or patch availability mentioned. Security practitioners should isolate affected devices, restrict administrative access, and monitor for anomalous command execution until firmware updates are provided.

Notably, the public disclosure of the exploit increases the risk of real-world exploitation against unpatched TRENDnet TEW-822DRE routers still in use.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

Secure engineering principles include proper neutralization and safe command construction practices.
