Summary
CVE-2023-49237 is a critical-severity Command Injection (CWE-77) vulnerability in Trendnet Tv-Ip1314Pi Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 3% 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-2023-49237 affects TRENDnet TV-IP1314PI devices running firmware version 5.5.3 200714. The vulnerability is a command injection flaw (CWE-77) in the davinci process, which invokes the system function to unpack language packs without properly sanitizing URL strings supplied during the operation.
An unauthenticated remote attacker can supply a crafted URL to trigger arbitrary command execution on the device. Successful exploitation yields full control over the affected camera, including the ability to read, modify, or delete data and to disrupt device availability, consistent with the CVSS 9.8 rating reflecting network-accessible attack with no required privileges or user interaction.
Researcher disclosures hosted on GitHub and Google Drive provide technical details and proof-of-concept material for the issue, but no vendor advisory or firmware patch addressing mitigation steps is referenced in the available sources. The associated EPSS score has remained steady at 0.6980, indicating sustained exploitation interest since publication.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover command-construction flaws before deployment.
Input validation directly stops construction of commands from untrusted data containing special elements.
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.
A.8.25 mandates secure SDLC practices including secure coding guidelines, security requirements, checkpoints, testing (scans/penetration), and developer training that reduce command injection defects, but leaves a minority slice (e.g. incomplete implementation of those practices, outsourced development without full assurance, or post-SDLC changes) where the weakness can still arise and be exploitable.
Application security requirements explicitly call for controls against injection flaws including command injection.
A.8.27 mandates security-by-design principles (e.g. distrust external input, secure session control, data validation/sanitization, least privilege) and design reviews that can stop command injection from being introduced, but this is only a minority slice of CWE-77 because the weakness can still arise in code that bypasses those principles, in non-reviewed components, or in runtime injection vectors the architecture review does not reach.
Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.
Security testing in development catches command-injection vulnerabilities before release.
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-77, a class-level weakness, and none of its children carries one either.
