Summary

CVE-2023-24261 is a high-severity OS Command Injection (CWE-78) vulnerability in Gl-Inet Gl-E750 Firmware. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); 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.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A vulnerability tracked as CVE-2023-24261 affects the GL.iNET GL-E750 Mudi router in firmware versions prior to v3.216. The flaw, classified under CWE-78, permits command injection and carries a CVSS 3.1 score of 7.2. It is triggered when an authenticated user submits a specially crafted POST request to the device.

An attacker who already possesses administrative credentials can send the malicious request over the network to execute arbitrary commands on the underlying operating system. Successful exploitation grants full control over the device, allowing the attacker to read or modify data, alter device behavior, and disrupt availability.

The affected firmware versions are those earlier than v3.216; the vendor indicates that updating to v3.216 resolves the issue. Public references consist of technical write-ups that detail the request format used to trigger the injection. The associated EPSS score has remained flat at 0.0664 with no material increase since disclosure.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
