CVE-2023-34364
📋 TL;DR
This vulnerability allows remote code execution via buffer overflow in Progress DataDirect Connect for ODBC Oracle Wire Protocol driver. Attackers can exploit overly large connection string options to execute arbitrary code on affected systems. Organizations using this ODBC driver for Oracle database connectivity are at risk.
💻 Affected Systems
- Progress DataDirect Connect for ODBC Oracle Wire Protocol driver
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining complete control over the host, enabling data theft, lateral movement, and persistent access.
Likely Case
Database server compromise leading to data exfiltration, credential theft, and potential ransomware deployment.
If Mitigated
Limited impact due to network segmentation and least privilege access controls, potentially only affecting the ODBC service.
🎯 Exploit Status
Buffer overflow vulnerabilities with remote code execution potential are frequently weaponized. The vulnerability requires sending a malicious connection string, which could be done through various applications using the ODBC driver.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 08.02.2770 and later
Vendor Advisory: https://community.progress.com/s/article/Security-vulnerabilities-in-DataDirect-ODBC-Oracle-Wire-Protocol-driver-June-2023
Restart Required: Yes
Instructions:
1. Download the updated driver version 08.02.2770 or later from Progress Software. 2. Uninstall the current vulnerable ODBC driver. 3. Install the updated driver. 4. Restart any services or applications using the ODBC driver. 5. Test database connectivity.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation for connection strings in applications using the ODBC driver
Network Segmentation
allRestrict network access to systems using the vulnerable ODBC driver
🧯 If You Can't Patch
- Implement strict network segmentation to isolate systems using the vulnerable ODBC driver
- Deploy application-level firewalls or WAFs to monitor and block suspicious connection string patterns
🔍 How to Verify
Check if Vulnerable:
Check the ODBC driver version in ODBC Data Source Administrator (Windows) or odbcinst -j (Linux). Verify version is earlier than 08.02.2770.Check Version:
Windows: Check ODBC Data Source Administrator properties. Linux: odbcinst -q -d | grep -i oracleVerify Fix Applied:
Confirm ODBC driver version is 08.02.2770 or later and test database connectivity through the driver.📡 Detection & Monitoring
Log Indicators:
- Unusually long connection strings in application logs
- Failed ODBC connection attempts with malformed parameters
- Process crashes related to odbc32.dll or ODBC driver processes
Network Indicators:
- Unusual network traffic to ODBC ports (typically 1521 for Oracle)
- Connection strings exceeding normal length in network captures
