CVE-2024-22346
📋 TL;DR
This vulnerability in IBM Db2 for i allows a local user to escalate privileges through an unqualified library call, enabling execution of user-controlled code with administrator privileges. It affects Db2 for IBM i versions 7.2 through 7.5. The attacker must have local access to the system.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where a local attacker gains full administrator privileges, potentially leading to data theft, system manipulation, or persistence mechanisms.
Likely Case
Local privilege escalation allowing attackers to bypass security controls, access sensitive data, or modify system configurations.
If Mitigated
Limited impact if proper access controls restrict local user accounts and privilege separation is enforced.
🎯 Exploit Status
Exploitation requires local access but appears to be straightforward once access is obtained. No public exploit code has been identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply IBM i PTF Group SF99738 Level 27 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/7140499
Restart Required: Yes
Instructions:
1. Check current PTF level with DSPPTF. 2. Apply PTF Group SF99738 Level 27 or later. 3. Restart the system as required. 4. Verify the fix with DSPPTF.
🔧 Temporary Workarounds
Restrict local user access
allLimit local user accounts to only trusted personnel and implement strict access controls.
Implement privilege separation
allEnsure users operate with least privilege and separate administrative functions from regular user activities.
🧯 If You Can't Patch
- Implement strict access controls to limit local user accounts to only essential personnel
- Monitor for suspicious privilege escalation attempts and review user activity logs regularly
🔍 How to Verify
Check if Vulnerable:
Check IBM i version and PTF level. Vulnerable if running Db2 for i 7.2-7.5 without PTF Group SF99738 Level 27 or later.
Check Version:
DSPPTF to check PTF levels, or WRKSYSVAL QVERSION to check OS version
Verify Fix Applied:
Verify PTF Group SF99738 Level 27 or later is installed using DSPPTF command.
📡 Detection & Monitoring
Log Indicators:
- Unusual privilege escalation attempts
- Suspicious library calls or DLL injections
- Unexpected administrative actions from non-admin accounts
Network Indicators:
- Not applicable - local exploitation only
SIEM Query:
Search for privilege escalation events, unexpected admin privilege usage, or security log entries indicating library manipulation
