CVE-2024-28100 | Stored Cross-site Scripting leading to arbitrary actions taken on behalf of users in elabftw

eLabFTW is an open source electronic lab notebook for research labs. By uploading specially crafted files, a regular user can create a circumstance where a visitor's browser runs arbitrary JavaScript code in the context of the eLabFTW application. This can be triggered by the visitor viewing a list of experiments. Viewing this allows the malicious script to act on behalf of the visitor in any way, including the creation of API keys for persistence, or other options normally available to the user. If the user viewing the page has the sysadmin role in eLabFTW, the script can act as a sysadmin (including system configuration and extensive user management roles). Users are advised to upgrade to at least version 5.0.0. There are no known workarounds for this vulnerability.

8.9 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:L 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:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
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:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
