CVE-2024-46628
RCE in Tendacn G3 Firmware 15.03.05.05
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-2024-46628 is a critical-severity OS Command Injection (CWE-78) vulnerability in Tendacn G3 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 4% 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.
Tenda G3 Router firmware version 15.03.05.05 contains a remote code execution vulnerability in the formSetUSBPartitionUmount function, where the usbPartitionName parameter is processed without adequate sanitization. The flaw is tracked as CVE-2024-46628 and is classified under CWE-78 as an instance of OS command injection, carrying a CVSS 3.1 score of 9.8 that reflects network-accessible exploitation without authentication or user interaction.
An unauthenticated attacker can supply a crafted usbPartitionName value over the network to execute arbitrary operating-system commands on the device. Successful exploitation grants full control over the router, enabling actions such as configuration changes, traffic interception, or use of the device as a foothold for further attacks on connected networks.
The single public reference is a technical disclosure containing proof-of-concept details rather than vendor guidance. No official patch or mitigation advisory is referenced in the available sources.
The EPSS score for this CVE rose from a low baseline to a peak of 0.2450, indicating that exploitation interest increased after disclosure and that the issue merits renewed monitoring.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

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.
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).
