CVE-2025-47411: Apache StreamPipes Privilege Escalation

CVE-2025-47411 Overview

CVE-2025-47411 is a privilege escalation vulnerability in Apache StreamPipes that allows a user with a legitimate non-administrator account to exploit a flaw in the user ID creation mechanism. This vulnerability enables attackers to swap the username of an existing user with that of an administrator, effectively gaining unauthorized administrative access to the application.

The vulnerability allows attackers to manipulate JWT tokens to gain administrative control over the StreamPipes application, which can lead to data tampering, unauthorized access to sensitive information, and other serious security issues.

Critical Impact

Attackers with low-privileged accounts can escalate to administrator privileges by manipulating the user ID creation mechanism, enabling full administrative control over Apache StreamPipes deployments.

Affected Products

• Apache StreamPipes versions through 0.97.0
• All installations running vulnerable versions without the security patch
• Organizations using Apache StreamPipes for IoT data processing and analytics

Technical Details for CVE-2025-47411

Vulnerability Analysis

This privilege escalation vulnerability (CWE-269: Improper Privilege Management) exists in the user ID creation mechanism within Apache StreamPipes. The flaw allows authenticated users with limited privileges to manipulate the system in a way that enables them to assume the identity of an administrator user.

The attack is network-accessible and requires low privileges to execute, making it particularly dangerous in multi-tenant environments or organizations where multiple users have access to the StreamPipes platform. Once exploited, an attacker gains the same level of access as an administrator, allowing them to modify configurations, access all data streams, and potentially compromise the integrity of the entire data processing pipeline.

The vulnerability's impact is significant because it affects both confidentiality and integrity of the system. Attackers can read sensitive data they shouldn't have access to and modify system configurations or data processing workflows.

Root Cause

The root cause of this vulnerability lies in improper privilege management within the user ID creation mechanism. The system fails to adequately validate and enforce proper privilege boundaries when user identities are being processed. This allows an authenticated attacker to manipulate the relationship between user IDs and associated privileges, specifically targeting the username swap functionality that should only be available to administrators.

The JWT token handling mechanism compounds this issue by accepting manipulated tokens that result from the exploited user ID creation process, effectively granting elevated privileges to the attacker.

Attack Vector

The attack vector for CVE-2025-47411 is network-based and requires the attacker to have a legitimate non-administrator account on the target Apache StreamPipes instance. The attack flow involves:

1. The attacker authenticates with their legitimate low-privilege account
2. The attacker exploits the user ID creation mechanism to swap their username with an administrator's username
3. The system generates or accepts a JWT token that reflects the swapped identity
4. The attacker now has administrative access to the StreamPipes application

This is a particularly concerning attack because it requires minimal technical sophistication once access to a valid account is obtained. The attack does not require user interaction and can be executed remotely over the network. For detailed technical information, refer to the Apache Security Mailing List Discussion and the Open Wall OSS Security Update.

Detection Methods for CVE-2025-47411

Indicators of Compromise

• Unexpected changes in user account privileges or role assignments within StreamPipes
• JWT tokens with mismatched user identity claims compared to the original account
• Audit logs showing non-administrator accounts accessing administrator-only functionality
• Multiple authentication sessions from the same user with different privilege levels

Detection Strategies

• Monitor StreamPipes authentication logs for unusual privilege escalation patterns
• Implement alerting on any modifications to user role assignments or administrator accounts
• Review JWT token claims for inconsistencies between user IDs and assigned roles
• Correlate user activity logs to detect accounts performing actions beyond their assigned permissions

Monitoring Recommendations

• Enable comprehensive audit logging for all user management operations in StreamPipes
• Implement real-time monitoring for changes to user privileges and administrator account modifications
• Configure alerts for JWT token anomalies or authentication events that indicate identity manipulation
• Regularly audit user accounts and their associated privileges to detect unauthorized escalations

How to Mitigate CVE-2025-47411

Immediate Actions Required

• Upgrade Apache StreamPipes to version 0.98.0 or later immediately
• Audit all user accounts for unauthorized privilege escalations
• Review administrator account integrity and reset credentials if necessary
• Monitor for any suspicious activity from non-administrator accounts attempting privileged operations

Patch Information

Apache has released version 0.98.0 of StreamPipes which addresses this vulnerability. Users are strongly recommended to upgrade to this version or later to remediate the security issue. The patch corrects the user ID creation mechanism to prevent unauthorized username swapping and improves JWT token validation to ensure proper privilege enforcement.

For official patch details and download information, refer to the Apache Security Mailing List Discussion.

Workarounds

• Restrict network access to Apache StreamPipes to trusted users and networks only until patching is complete
• Implement additional network segmentation to limit exposure of the StreamPipes application
• Conduct thorough review of all user accounts and remove unnecessary accounts or privileges
• Enable additional authentication factors if supported to add a layer of security for administrator accounts
• Monitor administrator account activity closely for any signs of unauthorized access

# Example: Verify current StreamPipes version and plan upgrade
# Check installed version
docker inspect apache/streampipes-backend | grep -i version

# Pull updated image (after release)
docker pull apache/streampipes-backend:0.98.0

# Review and backup current configuration before upgrade
docker exec streampipes-backend cat /streampipes-backend/application.yml > streampipes-backup.yml
