{
"lang": "en",
"value": "Froxlor is a server administration panel. In versions 2.3.10 and earlier, the customer data-export (DataDump) cron fails to validate intermediate path components of the export destination: Froxlor\\FileDir::makeCorrectDir() contains an off-by-one in its path-component walk that skips the first segment below the customer home directory, and the guard in ExportCron.php checks only the final component with is_link(). An authenticated customer whose account has the export feature enabled can schedule an export into a genuine subdirectory of their own webspace, then replace an intermediate path component with a symlink before the root-owned cron runs. The cron's `chown -R` then recursively changes ownership of the linked directory tree — for example /etc — to the customer's UID, yielding host root and cross-tenant compromise. Exploitation is deterministic and requires no race. This is an incomplete fix of GHSA-75h4-... The issue is fixed in Froxlor 2.3.12."
