CVE-2024-40645 | FOG Authenticated File Upload RCE

Exp

FOG is a cloning/imaging/rescue suite/inventory management system. An improperly restricted file upload feature allows authenticated users to execute arbitrary code on the fogproject server. The Rebranding feature has a check on the client banner image requiring it to be 650 pixels wide and 120 pixels high. Apart from that, there are no checks on things like file extensions. This can be abused by appending a PHP webshell to the end of the image and changing the extension to anything the PHP web server will parse. This vulnerability is fixed in 1.5.10.41.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
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:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
