Operationally, ranked in the top 22% 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 V6.2c.884 contains a command injection vulnerability in the setUploadUserData function, where the FileName parameter is not properly sanitized. The flaw is tracked as CVE-2023-24148 with a CVSS 3.1 score of 9.8 and is classified under CWE-77. It affects the web management interface of this PoE access point firmware version.
An unauthenticated attacker can send a crafted HTTP request over the network to the device and execute arbitrary operating system commands. Successful exploitation grants full control over the device, allowing reading or modifying sensitive data, altering device behavior, or causing denial of service.
The EPSS score for this CVE rose from a low baseline to a peak of 0.3113 on 2025-01-22 before receding to the current value of 0.1490, indicating a clear increase in observed exploitation interest well after the original disclosure. Public references consist of technical write-ups and proof-of-concept material hosted on GitHub, but no vendor advisory or patch information is included in the supplied references.

Mitigating Controls
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.
