Summary
CVE-2025-3987 is a medium-severity Injection (CWE-74) vulnerability in Totolink N150Rt Firmware. Its CVSS base score is 5.3 (Medium).
Operationally, 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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-3987 is a command injection vulnerability in the TOTOLINK N150RT wireless router running firmware version 3.4.0-B20190525. The flaw resides in the processing of the /boafrm/formWsc endpoint, where unsanitized input to the localPin argument allows arbitrary command execution. It is tracked under CWE-74 and CWE-77 and carries a CVSS 4.0 score of 5.3.
An authenticated remote attacker can supply a crafted localPin value to the affected form handler and execute operating-system commands on the device. The attack requires no user interaction and can be launched over the network, resulting in limited but direct effects on confidentiality, integrity, and availability of the router.
Public references include a detailed proof-of-concept on GitHub and entries on VulDB, confirming that exploit code has been disclosed. No vendor advisory or patch information is provided in the available sources, and the EPSS score has remained flat at 0.1192 with no observed increase after publication.

Mitigating Controls
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.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development catches injection vulnerabilities before release.
Monitoring activities can identify active injection attacks after they occur.
Secure coding standards require proper neutralization of special elements, directly addressing CWE-74.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-74, a class-level weakness, and none of its children carries one either.
- No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
