CVE-2023-26277
📋 TL;DR
This vulnerability in IBM QRadar WinCollect Agent allows local users to execute arbitrary commands with elevated privileges due to unnecessary privilege assignment. It affects users running WinCollect Agent versions 10.0 through 10.1.3 on Windows systems where local access is possible.
💻 Affected Systems

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Local attacker gains full system control, installs persistent malware, steals credentials, and pivots to other systems in the network.
Likely Case
Local user escalates privileges to administrator level, accesses sensitive data, or disrupts security monitoring functions.
If Mitigated
Attack limited to user-level actions if proper access controls and privilege separation are implemented.
🎯 Exploit Status
Requires local user access but exploitation is straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 10.1.4 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/6999343
Restart Required: Yes
Instructions:
1. Download WinCollect Agent version 10.1.4 or later from IBM Fix Central. 2. Stop the WinCollect service. 3. Run the installer with administrative privileges. 4. Restart the system or service as prompted.
🔧 Temporary Workarounds
Restrict Local Access
windowsLimit local user access to systems running WinCollect Agent to trusted administrators only.
Reduce Privileges
windowsConfigure WinCollect Agent to run with minimum necessary privileges instead of elevated rights.
🧯 If You Can't Patch
- Isolate affected systems from critical network segments and implement strict access controls.
- Monitor for privilege escalation attempts and unusual process execution from WinCollect directories.
🔍 How to Verify
Check if Vulnerable:
Check WinCollect Agent version in Control Panel > Programs and Features or via 'wmic product get name,version' command.Check Version:
wmic product where "name like '%WinCollect%'" get name,versionVerify Fix Applied:
Verify installed version is 10.1.4 or later and check service privileges are properly configured.📡 Detection & Monitoring
