CVE-2019-13658
📋 TL;DR
CVE-2019-13658 is a critical vulnerability in CA Network Flow Analysis software where default credentials allow remote attackers to execute arbitrary commands. This affects all systems running vulnerable versions, potentially leading to complete system compromise. Organizations using CA Network Flow Analysis 9.x or 10.0.x are at risk.
💻 Affected Systems
- CA Network Flow Analysis
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover, data exfiltration, lateral movement across network, and persistent backdoor installation.
Likely Case
Remote command execution leading to service disruption, data theft, and potential ransomware deployment.
If Mitigated
Limited impact with proper credential management and network segmentation, though risk remains if default credentials exist.
🎯 Exploit Status
Exploit code is publicly available and requires minimal technical skill to execute.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply patches from Broadcom security advisory
Restart Required: Yes
Instructions:
1. Download and apply the latest security patches from Broadcom. 2. Change all default credentials immediately. 3. Restart affected services. 4. Verify no default credentials remain.
🔧 Temporary Workarounds
Change Default Credentials
allImmediately change all default passwords and usernames on CA Network Flow Analysis installations
Use CA Network Flow Analysis administration interface to change credentials
Network Segmentation
allRestrict network access to CA Network Flow Analysis systems
Configure firewall rules to limit access to trusted IPs only
🧯 If You Can't Patch
- Immediately change all default credentials and implement strong password policies
- Isolate affected systems in a segmented network zone with strict access controls
🔍 How to Verify
Check if Vulnerable:
Check if CA Network Flow Analysis 9.x or 10.0.x is installed and if default credentials are still in useCheck Version:
Check version through CA Network Flow Analysis administration interface or system documentationVerify Fix Applied:
Verify that patches are applied, default credentials are changed, and system is not accessible with default credentials📡 Detection & Monitoring
Log Indicators:
- Failed login attempts with default usernames
- Unusual command execution patterns
- Authentication from unexpected IP addresses
Network Indicators:
- Traffic to CA Network Flow Analysis ports from unauthorized sources
- Suspicious outbound connections from affected systems
SIEM Query:
source="CA Network Flow Analysis" AND (event_type="authentication" AND (username="admin" OR username="default")) OR (event_type="command_execution" AND user="default_user")🔗 References
