valtimo-backend-libraries: Improper Neutralization of Special Elements used in an OS Command
CVE-2025-58059 is a critical-severity improper neutralization of special elements used in an OS command vulnerability in valtimo-backend-libraries from Valtimo-platform, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. Affected valtimo-backend-libraries versions: < 12.16.0.RELEASE; >= 13.0.0.RELEASE, < 13.1.2.RELEASE. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.4% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of valtimo-backend-libraries you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.

Official description
Valtimo is a platform for Business Process Automation. In versions before 12.16.0.RELEASE, and from 13.0.0.RELEASE to before 13.1.2.RELEASE, any admin that can create or modify and execute process-definitions could gain access to sensitive data or resources. This includes but is not limited to: running executables on the application host, inspecting and extracting data from the host environment or application properties, spring beans (application context, database pooling). The following conditions have to be met in order to perform this attack: the user must be logged in, have the admin role, and must have some knowledge about running scripts via a the Camunda/Operator engine. Version 12.16.0 and 13.1.2 have been patched. It is strongly advised to upgrade. If no scripting is needed in any of the processes, it could be possible to disable it altogether via the ProcessEngineConfiguration. However, this workaround could lead to unexpected side-effects.

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.
