Summary

CVE-2024-24329 is a critical-severity OS Command Injection (CWE-78) vulnerability in Totolink A3300R Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

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 A3300R routers running firmware version V17.0.0cu.557_B20221024 contain a command injection vulnerability in the setPortForwardRules function, where the enable parameter is passed to the system without proper sanitization. The flaw is tracked as CVE-2024-24329 and is classified under CWE-78, carrying a CVSS 3.1 score of 9.8 that reflects network-accessible exploitation without authentication or user interaction.

An unauthenticated attacker with network access can supply a crafted enable value to execute arbitrary operating-system commands on the device. Successful exploitation grants full control over the router, allowing an adversary to read or modify configuration data, intercept traffic, or pivot into the attached network.

Public proof-of-concept code has been posted to GitHub detailing the injection vector. The associated EPSS score currently stands at 0.8329 with an identical peak value, indicating sustained exploitation interest since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

SI-10 Information Input Validation good match

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

AC-6 Least Privilege partial match

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

CM-7 Least Functionality partial match

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require proper neutralization of untrusted input before command construction.

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).

Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.
