FAUCET Score

CVE-2018-19422 is a critical arbitrary file upload vulnerability affecting Subrion CMS version 4.2.1, specifically within the /panel/uploads directory. An authenticated attacker can bypass security restrictions by uploading malicious .pht or .phar files, which are not properly blocked by the .htaccess configuration. This allows for remote code execution (RCE) with a high impact on confidentiality, integrity, and availability, as reflected by its CVSS score of 7.2 (High) and a FAUCET Risk Score of 99/100.
