CVE-2014-3699
📋 TL;DR
CVE-2014-3699 is a critical remote code execution vulnerability in eDeploy's cPickle deserialization that allows attackers to execute arbitrary code by sending maliciously crafted data. This affects systems running vulnerable versions of eDeploy, particularly those exposed to untrusted network input. Organizations using eDeploy for system deployment and configuration management are at risk.
💻 Affected Systems
- eDeploy
📦 What is this software?
Edeploy by Redhat
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to execute arbitrary commands with the privileges of the eDeploy service, potentially leading to data theft, lateral movement, or persistent backdoors.
Likely Case
Remote code execution leading to unauthorized access, data exfiltration, or deployment of malware on managed systems.
If Mitigated
Limited impact with proper network segmentation and access controls, potentially only affecting isolated deployment environments.
🎯 Exploit Status
Exploitation is straightforward due to cPickle's inherent insecurity with untrusted data. Attackers can craft malicious pickle objects to achieve RCE.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Distribution-specific (e.g., Red Hat: eDeploy updates in 2014; Debian: fixed in security updates)
Vendor Advisory: https://access.redhat.com/security/cve/cve-2014-3699
Restart Required: Yes
Instructions:
1. Check your distribution's security advisories. 2. Apply the latest eDeploy package updates via your package manager. 3. Restart eDeploy services to apply the patch.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to eDeploy services to trusted IP addresses only
iptables -A INPUT -p tcp --dport [eDeploy_port] -s [trusted_network] -j ACCEPT
iptables -A INPUT -p tcp --dport [eDeploy_port] -j DROP
Disable Vulnerable Components
linuxTemporarily disable eDeploy services or specific cPickle-based functionality if not essential
systemctl stop edeploy
service edeploy stop
🧯 If You Can't Patch
- Implement strict network segmentation to isolate eDeploy systems from untrusted networks
- Monitor eDeploy logs for suspicious deserialization attempts and implement application-level input validation
🔍 How to Verify
Check if Vulnerable:
Check eDeploy version and compare against patched versions in your distribution's security advisoryCheck Version:
rpm -q edeploy # Red Hat/CentOS or dpkg -l | grep edeploy # Debian/UbuntuVerify Fix Applied:
Verify eDeploy package version matches or exceeds the patched version from vendor advisories📡 Detection & Monitoring
Log Indicators:
- Unusual cPickle deserialization errors
- Suspicious process execution from eDeploy service
- Unexpected network connections from eDeploy hosts
Network Indicators:
- Malformed pickle data sent to eDeploy ports
- Unexpected outbound connections from eDeploy systems
