Operationally, ranked in the top 0.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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-2023-46574 is a command-injection vulnerability (CWE-77) affecting the TOTOLINK A3700R wireless router running firmware version 9.1.2u.6165_20211012. The flaw resides in the UploadFirmwareFile function, where the FileName parameter is insufficiently sanitized before being passed to a system command, enabling arbitrary code execution. The issue carries a CVSS 3.1 base score of 9.8 with a network attack vector, low complexity, and no required privileges or user interaction.
An unauthenticated remote attacker can send a crafted HTTP request containing a malicious FileName value to the router’s firmware-upload endpoint. Successful exploitation grants the attacker the ability to execute operating-system commands with the privileges of the web-server process, resulting in complete control over the device, including the capacity to read or modify configuration and firmware data or to pivot into the attached network.
Public references consist of technical write-ups hosted on GitHub that reproduce the flaw but do not describe vendor patches or mitigation steps. The associated EPSS score remains elevated (current 0.9358, peak 0.9402), indicating sustained exploitation interest since disclosure.

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.
