Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/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-2023-24161 is a critical-severity Command Injection (CWE-77) vulnerability in Totolink Ca300-Poe Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 21% 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.
TOTOLINK CA300-PoE firmware version V6.2c.884 contains a command injection vulnerability in the setWebWlanIdx function triggered by the webWlanIdx parameter. The flaw is tracked as CWE-77 and rated 9.8 under CVSS 3.1, reflecting that it is reachable over the network without credentials or user interaction and can impact confidentiality, integrity, and availability.
An unauthenticated remote attacker can supply a malicious webWlanIdx value in an HTTP request to the device, causing the web interface to execute arbitrary operating-system commands. Successful exploitation yields full control of the affected access point, enabling data exfiltration, configuration changes, or denial of service.
Public details and proof-of-concept material appear in repositories that document the parameter handling flaw, but no vendor advisory or firmware update is referenced in the available sources. The associated EPSS score stands at 0.1490 with no material increase from an earlier lower baseline.

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.
