CVE-2024-39733
📋 TL;DR
IBM Datacap Navigator versions 9.1.5 through 9.1.9 store user credentials in plain text, allowing local users to read sensitive authentication data. This vulnerability affects organizations using these specific versions of IBM Datacap Navigator.
💻 Affected Systems
- IBM Datacap Navigator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Local attackers gain administrative credentials, leading to complete system compromise, data theft, and privilege escalation across connected systems.
Likely Case
Malicious insiders or compromised local accounts harvest credentials for lateral movement and unauthorized access to sensitive data.
If Mitigated
With strict access controls and monitoring, impact is limited to credential exposure on individual systems without broader compromise.
🎯 Exploit Status
Exploitation requires local system access but involves simple file reading of stored credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply interim fix or upgrade to version 9.1.10 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/7160185
Restart Required: Yes
Instructions:
1. Download the interim fix from IBM Fix Central. 2. Apply the fix following IBM's installation instructions. 3. Restart the Datacap Navigator service. 4. Verify credentials are no longer stored in plain text.
🔧 Temporary Workarounds
Restrict Local Access
allLimit local user access to systems running Datacap Navigator to trusted administrators only.
File System Permissions
linuxSet strict file permissions on credential storage locations to prevent unauthorized reading.
chmod 600 /path/to/credential/files
chown root:root /path/to/credential/files
🧯 If You Can't Patch
- Implement strict access controls to limit local user access to affected systems
- Monitor for unusual local file access patterns and credential usage
🔍 How to Verify
Check if Vulnerable:
Check if Datacap Navigator version is between 9.1.5 and 9.1.9 inclusive, and search for plain text credential files in application directories.Check Version:
Check Datacap Navigator administration console or installation directory for version informationVerify Fix Applied:
After patching, verify no credentials are stored in plain text and check that version is 9.1.10 or later.📡 Detection & Monitoring
Log Indicators:
- Unauthorized file access attempts to credential storage locations
- Multiple failed authentication attempts followed by successful logins
Network Indicators:
- Unusual authentication patterns from previously unused accounts
- Lateral movement from affected systems
