CVE-2025-15139
Published: 28 December 2025
Summary
CVE-2025-15139 is a medium-severity Injection (CWE-74) vulnerability in Trendnet Tew-822Dre Firmware. Its CVSS base score is 6.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 30.5% 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Requires validation and sanitization of the peerPin input parameter to directly prevent command injection in the /boafrm/formWsc function.
Mandates timely remediation of identified flaws like this command injection vulnerability through patching or compensatory controls.
Enforces least privilege for low-privileged (PR:L) authenticated users, limiting the scope and impact of any successfully injected commands.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Command injection in router web interface (/boafrm/formWsc) enables exploitation of public-facing application (T1190), exploitation of remote services (T1210), and Unix Shell command execution (T1059.004).
NVD Description
A vulnerability has been found in TRENDnet TEW-822DRE 1.00B21/1.01B06. This affects the function sub_43ACF4 of the file /boafrm/formWsc. Such manipulation of the argument peerPin leads to command injection. The attack can be executed remotely. The exploit has been disclosed to…

the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Deeper analysisAI
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.
