How to Fix CVE-2024-24770

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: 4.3.0 
pip install vantage6>=4.3.0
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-2024-24770, 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 4.3.0), 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-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. 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 Much like https://github.com/vantage6/vantage6/security/advisories/GHSA-45gq-q4xh-cp53, it is possible to find which usernames exist in vantage6 by calling the API routes `/recover/lost` and `/2fa/lost`, which send emails to users if they have lost their password or MFA token. Usernames can be found by assessing response time differences, and additionally, they can be found because the endpoint gives a response "Failed to login" if the username exists. ### Patches No ### Workarounds No
