How to Fix CVE-2023-28635

To remediate this vulnerability, upgrade all affected Vantage6 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

vantage6 fixed: 4.0.0 
pip install vantage6>=4.0.0
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 vantage6

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-28635, inspect your installed packages using pip:

pip show vantage6

Analyze the terminal output to locate any version of Vantage6 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.0), your application is affected.

Note: The pip show vantage6 command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Vantage6, 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

### Impact Malicious users may try to get access to resources they are not allowed to see, by creating resources with integers as names. One example where this is a risk, is when users define which users are allowed to run algorithms on their node. This may be defined by username or user id. Now, for example, if user id 13 is allowed to run tasks, and an attacker creates a username with username '13', they would be wrongly allowed to run an algorithm. There may also be other places in the code where such a mixup of resource ID or name leads to issues. The best solution we see is therefore to check when resources are created or modified, that the resource name always starts with a character. ### Patches To be done, probably in v3.9 ### Workarounds None
