CVE-2019-19731

Exp

Roxy Fileman 1.4.5 for .NET is vulnerable to path traversal. A remote attacker can write uploaded files to arbitrary locations via the RENAMEFILE action. This can be leveraged for code execution by uploading a specially crafted Windows shortcut file and writing the file to the Startup folder (because an incomplete blacklist of file extensions allows Windows shortcut files to be uploaded).

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
