CVE-2024-8374 | Arbitrary Code Injection in Cura

UltiMaker Cura slicer versions 5.7.0-beta.1 through 5.7.2 are vulnerable to code injection via the 3MF format reader (/plugins/ThreeMFReader.py). The vulnerability arises from improper handling of the drop_to_buildplate property within 3MF files, which are ZIP archives containing the model data. When a 3MF file is loaded in Cura, the value of the drop_to_buildplate property is passed to the Python eval() function without proper sanitization, allowing an attacker to execute arbitrary code by crafting a malicious 3MF file. This vulnerability poses a significant risk as 3MF files are commonly shared via 3D model databases.

Base score Version Severity Vector Exploitability Impact Score source
7.8 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
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:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
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.
