Summary

Cacti: Arbitrary File Read via Path Traversal in Report `format_file` Parameter

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 formatfile Parameter, causing arbitrary file read. This vulnerability occurs in two stages. In the first stage (stored injection), lib/htmlreports.php at line 283 stores $save['formatfile'] = $post['formatfile'] directly into the database without any validation. In the second stage (file read), lib/reports.php at line 667 concatenates CACTIPATHFORMATS . '/' . $formatfile, and line 670 then calls file($formatfile), reading arbitrary files from the filesystem. This issue has been fixed in version 1.2.31.
