CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2025-44658 impacting netgear rax30_firmware. Evaluated with CVSS Base Score of 9.8 (CRITICAL).

Original NVD Description

Source: NIST NVD
In Netgear RAX30 V1.0.10.94, a PHP-FPM misconfiguration vulnerability is caused by not following the specification to only limit FPM to .php extensions. An attacker may exploit this by uploading malicious scripts disguised with alternate extensions and tricking the web server into executing them as PHP, bypassing security mechanisms based on file extension filtering. This may lead to remote code execution (RCE), information disclosure, or full system compromise.
