Summary

CVE-2025-34030 is a critical-severity OS Command Injection (CWE-78) vulnerability. Its CVSS base score is 10.0 (Critical).

Operationally, ranked in the top 5.3% 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 OS command injection vulnerability exists in sar2html version 3.2.2 and prior via the plot parameter in index.php. The application fails to sanitize user-supplied input before using it in a system-level context, allowing commands to be executed through the web interface.

Remote, unauthenticated attackers can exploit the flaw by appending shell commands to the plot parameter in a crafted GET request, such as ?plot=;id. After interacting with the host selection UI, the command output is returned in the application interface, resulting in arbitrary command execution on the underlying system with full impact across confidentiality, integrity, and availability.

Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-04 UTC. The EPSS score reached a peak of 0.1491 with no material rise from a lower baseline.

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.
