CyberRota Analysis
AI-GeneratedFroxlor versions up to 2.3.10 are vulnerable to arbitrary file deletion due to improper handling of symlinks in the FTP data deletion cron task, allowing authenticated users to exploit this flaw. The impact includes potential cross-tenant data destruction and denial of service, as malicious users can craft symlinks to trigger recursive deletion of arbitrary directories with root privileges. Organizations using Froxlor should prioritize upgrading to version 2.3.12 to mitigate this critical vulnerability.

Original NVD Description
Froxlor through 2.3.10 is vulnerable to arbitrary file deletion via symlink following in the FTP data deletion cron task. Cron task 8 (deleteFtpData), queued when an FTP account is deleted, calls FileDir::makeCorrectDir() without the $fixed_homedir argument, so the symlink component walk is skipped, and then executes 'rm -rf' as root on the resulting path with string-level guards only. Because makeCorrectDir() appends a trailing slash, GNU rm dereferences a symlink used either as an intermediate path component or as the final component. An authenticated customer who can write to the FTP home directory can plant a symlink between task insertion and cron execution, causing the root cron job to recursively delete arbitrary directory trees, resulting in cross-tenant data destruction and host denial of service. This issue is fixed in Froxlor 2.3.12.
