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 Exploit Public-Facing Application (T1190); ranked in the top 5.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

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.

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.
