- CWE-59 - Improper Link Resolution Before File Access ('Link Following')
Summary
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.
