How to Fix CVE-2024-2035

To remediate this vulnerability, upgrade all affected Zenml dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

zenml fixed: 0.56.2 
pip install zenml>=0.56.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show zenml

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-2035, inspect your installed packages using pip:

pip show zenml

Analyze the terminal output to locate any version of Zenml in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.56.2), your application is affected.

Note: The pip show zenml command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1220: Insufficient Granularity of Access Control, where the product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. however, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. In Zenml, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An improper authorization vulnerability exists in the zenml-io/zenml repository, specifically within the API PUT /api/v1/users/id endpoint. This vulnerability allows any authenticated user to modify the information of other users, including changing the `active` status of user accounts to false, effectively deactivating them. This issue affects version 0.55.3 and was fixed in version 0.56.2. The impact of this vulnerability is significant as it allows for the deactivation of admin accounts, potentially disrupting the functionality and security of the application.
