Summary

CVE-2025-34042 is a critical-severity OS Command Injection (CWE-78) vulnerability in Cxsecurity (inferred from references). Its CVSS base score is 9.4 (Critical).

Operationally, ranked in the top 20.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

An authenticated command injection vulnerability affects the Beward N100 IP Camera running firmware version M2.1.6.04C014. The flaw resides in the servetest CGI page, where the ServerName and TimeZone parameters are passed directly into backend system calls without sanitization, enabling arbitrary command execution under the CWE-78 category.

An attacker who already possesses valid credentials to the web interface can supply malicious input in these parameters to execute system commands with root privileges, resulting in full remote code execution on the device. The CVSS 4.0 score of 9.4 reflects the high impact across confidentiality, integrity, and availability when network access is available.

Exploitation evidence was recorded by the Shadowserver Foundation on 2024-12-02 UTC. The EPSS score remains flat at a peak and current value of 0.0127 with no material increase after disclosure.

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.
