CVE-2016-8954
📋 TL;DR
IBM dashDB Local contains hard-coded credentials that could allow remote attackers to gain unauthorized access to Docker containers or the database itself. This affects organizations using vulnerable versions of IBM dashDB Local, potentially exposing sensitive data and system control.
💻 Affected Systems
- IBM dashDB Local
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the dashDB database and Docker container, allowing data theft, data manipulation, privilege escalation, and potential lateral movement to other systems.
Likely Case
Unauthorized access to sensitive database information, potential data exfiltration, and possible denial of service through container manipulation.
If Mitigated
Limited impact with proper network segmentation and access controls, though credentials remain exposed to anyone with network access.
🎯 Exploit Status
Exploitation requires only knowledge of the hard-coded credentials and network access to the service.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.0.0.2 and later
Vendor Advisory: http://www.ibm.com/support/docview.wss?uid=swg21994471
Restart Required: Yes
Instructions:
1. Download and install IBM dashDB Local version 1.0.0.2 or later from IBM Fix Central. 2. Stop all dashDB Local services. 3. Apply the update following IBM's installation instructions. 4. Restart dashDB Local services. 5. Verify the update was successful.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict network access to dashDB Local to only trusted hosts/networks
iptables -A INPUT -p tcp --dport [dashdb_port] -s [trusted_ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [dashdb_port] -j DROP
Credential Rotation
allManually change hard-coded credentials if possible (check IBM documentation)
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to dashDB Local
- Monitor for unauthorized access attempts and review access logs regularly
🔍 How to Verify
Check if Vulnerable:
Check dashDB Local version using the dashDB administration interface or by examining the Docker container version. Versions prior to 1.0.0.2 are vulnerable.Check Version:
docker ps | grep dashdb (to find container) then docker exec [container_id] cat /opt/ibm/dashdb/version.txtVerify Fix Applied:
Verify the installed version is 1.0.0.2 or later through the administration interface or by checking the Docker container image version.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts using hard-coded usernames
- Successful logins from unexpected IP addresses
- Database access patterns outside normal business hours
Network Indicators:
- Connection attempts to dashDB ports from unauthorized sources
- Unusual data transfer volumes from dashDB servers
SIEM Query:
source="dashdb" AND (event_type="authentication" AND (username="hardcoded_user" OR result="success"))
