CyberRota Analysis

AI-Generated

Boruta versions prior to 0.10.0 are vulnerable due to the logging of sensitive OAuth and OpenID Connect values, including access and refresh tokens, in business event logs. This exposure allows an attacker with access to these logs to potentially recover and misuse credentials until they expire or are revoked. Organizations utilizing Boruta for authorization should prioritize upgrading to version 0.10.0 to mitigate this risk.

Original NVD Description

Boruta is a standalone authorization server that aims to implement OAuth 2.0 and Openid Connect up to decentralized identity specifications. Prior to version 0.10.0, Boruta logged sensitive OAuth and OpenID Connect values in business event logs. Logged values could include access tokens, refresh tokens, authorization codes, agent tokens, direct-post codes, ID tokens, VP tokens, and tokens submitted to introspection or revocation endpoints. An attacker with access to Boruta logs, log aggregation systems, or the administration log viewer could recover these credentials and use them until expiration or revocation. This issue has been patched in version 0.10.0.
