Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-204: Observable Response Discrepancy, where the product provides different responses to incoming requests in a way that reveals internal state information to an unauthorized actor outside of the intended control sphere. 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 We are incorporating the password policies listed in https://github.com/vantage6/vantage6/issues/59. One measure is that we don't let the user know in case of wrong username/password combination if the username actually exists, to prevent that bots can guess usernames. However, if a wrong password is entered a number of times, the user account is blocked temporarily. This way you could still find out which usernames exist. ### Patches Update to 3.8.0+ ### Workarounds No ### References https://github.com/vantage6/vantage6/issues/59 ### For more information If you have any questions or comments about this advisory: * Email us at [vantage6@iknl.nl](mailto:vantage6@iknl.nl)
