Froxlor is open source server administration software. Prior to version 2.3.6, DataDump.add() constructs the export destination path from user-supplied input without passing the $fixed_homedir parameter to FileDir::makeCorrectDir(), bypassing the symlink validation that was added to all other customer-facing path operations (likely as the fix for CVE-2023-6069). When the ExportCron runs as root, it executes chown -R on the resolved symlink target, allowing a customer to take ownership of arbitrary directories on the system. Version 2.3.6 contains an updated fix.
AnalysisAI
Symlink-based privilege escalation in Froxlor versions prior to 2.3.6 allows authenticated customers to gain ownership of arbitrary system directories. When the ExportCron executes as root, it performs 'chown -R' on user-controlled export paths that bypass symlink validation (introduced to fix CVE-2023-6069), enabling attackers to place symbolic links and hijack ownership of critical system files. …
