Summary

CVE-2025-34151 is a critical-severity OS Command Injection (CWE-78) vulnerability in Chocapikk (inferred from references). Its CVSS base score is 9.4 (Critical).

Operationally, ranked in the top 17.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

A command injection vulnerability exists in the 'passwd' parameter of the PPPoE setup process on the Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02). The input is passed directly to system-level commands without sanitization, enabling unauthenticated attackers to achieve root-level code execution. The issue is tracked as CVE-2025-34151 with a CVSS 4.0 score of 9.4 and is classified under CWE-78.

Unauthenticated attackers with adjacent network access can supply a malicious 'passwd' value during PPPoE configuration to execute arbitrary commands as root. No authentication or user interaction is required, and successful exploitation grants full control over the device.

The EPSS score rose from a low baseline to a peak of 0.0430, indicating emerging exploitation interest after disclosure. Public references include detailed technical analysis from Chocapikk and an advisory from VulnCheck that document the flaw in the affected repeater hardware.

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.
