vantage6 vulnerable to Observable Response Discrepancy

Moderate severity GitHub Reviewed Published Feb 28, 2023 in vantage6/vantage6 • Updated Mar 9, 2023

Package

pip vantage6 (pip)

Affected versions

< 3.8.0

Patched versions

3.8.0

Description

Impact

We are incorporating the password policies listed in vantage6/vantage6#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

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
