Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-2649 is a high-severity Command Injection (CWE-77) vulnerability in Tenda Ac23 Firmware. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 5% 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-2023-2649 is a command injection vulnerability affecting Tenda AC23 routers running firmware version 16.03.07.45_cn. It resides in unknown code within the /bin/ate binary that listens on service port 7329, where unsanitized input supplied to the v2 argument is passed directly to a system command interpreter, corresponding to CWE-77.
An attacker with administrative credentials can exploit the flaw over the network to inject and execute arbitrary operating-system commands on the device. Successful exploitation grants full control over confidentiality, integrity, and availability of the router, consistent with the CVSS 7.2 rating that requires high privileges but no user interaction.
Public exploit code has been published on GitHub, and the vendor was notified prior to disclosure but provided no response or patch. The associated EPSS score has remained flat at 0.1784 with no material increase since publication.

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.
