CVE-2025-6505
📋 TL;DR
This vulnerability in Progress Software's Hybrid Data Pipeline Server allows attackers to combine OAuth client credentials from both HTTP headers and request parameters during authentication. This credential mixing enables client impersonation and unauthorized access to protected resources. Affected systems are Linux servers running Hybrid Data Pipeline Server version 4.6.2.3226 and below.
💻 Affected Systems
- Progress Software Hybrid Data Pipeline Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full administrative access to the Hybrid Data Pipeline Server, allowing them to exfiltrate sensitive data, modify configurations, or use the server as a pivot point to access connected backend systems.
Likely Case
Attackers impersonate legitimate OAuth clients to access data sources and APIs that the compromised client is authorized to use, potentially exposing sensitive business data.
If Mitigated
With proper network segmentation and monitoring, unauthorized access attempts are detected and blocked before significant damage occurs, though some data exposure may still happen.
🎯 Exploit Status
Exploitation requires understanding of OAuth protocol and ability to intercept/modify authentication requests. No public exploit code has been identified yet.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.6.2.3227 or later
Vendor Advisory: https://community.progress.com/s/article/DataDirect-Hybrid-Data-Pipeline-Critical-Security-Product-Alert-Bulletin-July-2025---CVE-2025-6505
Restart Required: Yes
Instructions:
1. Download the latest version from Progress Software support portal. 2. Backup current configuration and data. 3. Stop the Hybrid Data Pipeline service. 4. Install the updated version. 5. Restart the service. 6. Verify functionality.
🔧 Temporary Workarounds
Disable OAuth Authentication
linuxTemporarily disable OAuth authentication and use alternative authentication methods if possible
# Edit configuration file to disable OAuth
# Location typically: /opt/hybriddatapipeline/conf/server.properties
# Set: oauth.enabled=false
Network Access Control
linuxRestrict access to the Hybrid Data Pipeline Server to trusted IP addresses only
# Using iptables to restrict access
iptables -A INPUT -p tcp --dport 8443 -s TRUSTED_IP_RANGE -j ACCEPT
iptables -A INPUT -p tcp --dport 8443 -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the Hybrid Data Pipeline Server from untrusted networks
- Deploy a web application firewall (WAF) with rules to detect and block credential mixing attempts in OAuth requests
🔍 How to Verify
Check if Vulnerable:
Check the server version by examining the installation directory or running: cat /opt/hybriddatapipeline/VERSION.txtCheck Version:
cat /opt/hybriddatapipeline/VERSION.txtVerify Fix Applied:
Verify the version is 4.6.2.3227 or later and test OAuth authentication to ensure credentials are only accepted from one source (not both headers and parameters)📡 Detection & Monitoring
Log Indicators:
- Multiple authentication attempts with mixed credential sources in OAuth requests
- Failed OAuth handshakes followed by successful authentication from same source IP
- Unusual OAuth client activity patterns
Network Indicators:
- HTTP requests containing OAuth credentials in both headers and parameters
- Rapid succession of OAuth authentication attempts from single IP
SIEM Query:
source="hybriddatapipeline" AND (oauth_credential_source="mixed" OR (http_header.auth AND http_param.auth))
