Documentation server: Improper Neutralization of Special Elements used in an OS Command
CVE-2024-1624 is a critical-severity improper neutralization of special elements used in an OS command vulnerability in Documentation server from Dassault Systèmes, with a CVSS 3.1 base score of 9.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Documentation server versions: Release 3DEXPERIENCE R2022x Golden through Release 3DEXPERIENCE R2022x.FP.CFA.2406; Release 3DEXPERIENCE R2023x Golden through Release 3DEXPERIENCE R2023x FP.CFA.2350; Release 3DEXPERIENCE R2024x Golden through Release 3DEXPERIENCE R2024x.FP.CFA.2405, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 2.13% chance of exploitation within 30 days, higher than 82% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of Documentation server you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
An OS Command Injection vulnerability affecting documentation server on 3DEXPERIENCE from Release 3DEXPERIENCE R2022x through Release 3DEXPERIENCE R2024x, SIMULIA Abaqus from Release 2022 through Release 2024, SIMULIA Isight from Release 2022 through Release 2024 and CATIA Composer from Release R2023 through Release R2024. A specially crafted HTTP request can lead to arbitrary command execution.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
