CVE-2014-6120
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary commands on IBM Rational AppScan Source and Security AppScan Source installation servers via unspecified vectors. Attackers can gain full control of affected servers, potentially compromising the entire application security testing infrastructure. Organizations using vulnerable versions of these IBM application security testing products are affected.
💻 Affected Systems
- IBM Rational AppScan Source
- IBM Security AppScan Source
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the AppScan server, allowing attackers to execute arbitrary commands with system-level privileges, steal sensitive application security data, pivot to other systems, and deploy ransomware or other malware.
Likely Case
Attackers gain remote code execution on the AppScan server, enabling them to steal source code analysis results, modify security findings, and potentially access credentials stored in the system.
If Mitigated
Limited impact if server is isolated in a secure network segment with strict access controls, though the vulnerability still provides a foothold for lateral movement.
🎯 Exploit Status
IBM X-Force ID 96721 indicates unspecified vectors but CVSS 9.8 suggests trivial exploitation; no public exploit code found.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply IBM fix packs: Rational AppScan Source 8.0.0.3+, 8.5.0.2+; Security AppScan Source 8.6.0.3+, 8.7.0.2+, 8.8.0.1+, 9.0.0.2+, 9.0.1.1+
Vendor Advisory: https://exchange.xforce.ibmcloud.com/vulnerabilities/96721
Restart Required: Yes
Instructions:
1. Download appropriate fix pack from IBM Fix Central. 2. Backup current installation. 3. Apply fix pack following IBM instructions. 4. Restart AppScan services. 5. Verify installation.
🔧 Temporary Workarounds
Network Segmentation
allIsolate AppScan servers from untrusted networks and restrict access to authorized IPs only.
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.1.0/24" port port="<AppScan_port>" protocol="tcp" accept'
netsh advfirewall firewall add rule name="AppScan_Access" dir=in action=allow protocol=TCP localport=<AppScan_port> remoteip=192.168.1.0/24
Service Account Hardening
windowsRun AppScan services with minimal privileges to limit impact of command execution.
sc config "AppScanService" obj="NT AUTHORITY\LocalService"
Set-Service -Name "AppScanService" -StartupType "Automatic" -Credential (Get-Credential)
🧯 If You Can't Patch
- Immediately isolate affected servers in a dedicated VLAN with strict firewall rules allowing only necessary traffic
- Implement application-level firewall or WAF with command injection protection rules
🔍 How to Verify
Check if Vulnerable:
Check Help > About in AppScan GUI or run 'AppScan.exe -version' from command line and compare with affected versions list.Check Version:
AppScan.exe -versionVerify Fix Applied:
Verify version number is above patched threshold and test command injection attempts are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual process creation from AppScan service
- Suspicious command execution patterns in Windows Event Logs (4688)
- Failed authentication attempts followed by successful access
Network Indicators:
- Unexpected outbound connections from AppScan server
- Command and control traffic patterns
- Anomalous payloads in HTTP requests to AppScan
