CVE-2024-38530 | Open eClass Platform allows Arbitrary File Upload in "modules/h5p/save.php"

Exp

The Open eClass platform (formerly known as GUnet eClass) is a complete Course Management System. An arbitrary file upload vulnerability in the "save" functionality of the H5P module enables unauthenticated users to upload arbitrary files on the server's filesystem. This may lead in unrestricted RCE on the backend server, since the upload location is accessible from the internet. This vulnerability is fixed in 3.16.

9.8 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
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: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.
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.
