Froxlor has Incomplete Symlink Validation in DataDump.add() that Allows Arbitrary Directory Ownership Takeover via Cron

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.

Froxlor 后置链接漏洞

Froxlor是Froxlor团队的一套轻量级服务器管理软件。 Froxlor 2.3.6之前版本存在后置链接漏洞，该漏洞源于DataDump.add()在构建导出目标路径时未传递$fixed_homedir参数，绕过符号链接验证，导致客户可以获取系统上任意目录的所有权。
