Improper Restriction of Excessive Authentication Attempts in Sorcery

High severity GitHub Reviewed Published May 2, 2020 in Sorcery/sorcery • Updated May 16, 2023

Package

bundler sorcery (RubyGems)

Affected versions

< 0.15.0

Patched versions

0.15.0

Description

Impact

Brute force vulnerability when using password authentication via Sorcery. The brute force protection submodule will prevent a brute force attack for the defined lockout period, but once expired protection will not be re-enabled until a user or malicious actor logs in successfully. This does not affect users that do not use the built-in brute force protection submodule, nor users that use permanent account lockout.

Patches

Patched as of version 0.15.0.

Workarounds

Currently no workarounds, other than monkey patching the authenticate method provided by Sorcery or upgrading to version 0.15.0.

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.
