CVE-2022-39228: Observable Response Discrepancy in vantage6
First published: Tue Feb 28 2023(Updated: )
### 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)
