Executive Summary

This vulnerability involves Apache Ranger versions up to 2.8.0 logging replayable JWT bearer tokens. These tokens could be reused if intercepted, potentially allowing unauthorized access.

Detection Guidance

To detect this vulnerability, check Apache Ranger logs for JWT tokens in plaintext. Search logs for patterns like 'Bearer eyJ' or 'Authorization: Bearer' to identify exposed tokens. Ensure tokens are not stored in logs in versions <= 2.8.0.

Impact Analysis

If an attacker intercepts these tokens, they could replay them to gain unauthorized access to systems protected by Apache Ranger, potentially leading to data breaches or unauthorized actions.

Compliance Impact

This vulnerability could lead to unauthorized access, which may result in data breaches. Breaches can violate GDPR, HIPAA, and other regulations, potentially leading to legal penalties and reputational damage.

Mitigation Strategies

Upgrade Apache Ranger to version 2.9.0 or later to fix the issue with replayable JWT tokens in logs.
