  "details": "Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Path Traversal  through the Report format_file Parameter, causing arbitrary file read. This vulnerability occurs in two stages. In the first stage (stored injection), lib/html_reports.php at line 283 stores $save['format_file'] =  $post['format_file'] directly into the database without any validation. In the second stage (file read), lib/reports.php at line 667 concatenates  CACTI_PATH_FORMATS . '/' . $format_file, and line 670 then calls file($format_file), reading arbitrary files from the filesystem. This issue has been fixed in version 1.2.31.",
