CVE-2024-20953
📋 TL;DR
This vulnerability in Oracle Agile PLM allows authenticated attackers with network access to execute arbitrary code through deserialization of untrusted data. It affects Oracle Agile PLM version 9.3.6 and can lead to complete system compromise.
💻 Affected Systems
- Oracle Agile PLM
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete takeover of Oracle Agile PLM system, allowing attacker to steal sensitive data, modify records, disrupt operations, and potentially pivot to other systems.
Likely Case
Attacker gains full administrative control over PLM system, enabling data theft, manipulation of product lifecycle data, and installation of persistent backdoors.
If Mitigated
With proper network segmentation and access controls, impact limited to isolated PLM environment, preventing lateral movement to other systems.
🎯 Exploit Status
CISA lists as known exploited, ZDI advisory exists, requires low privileged credentials
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply Critical Patch Update from January 2024
Vendor Advisory: https://www.oracle.com/security-alerts/cpujan2024.html
Restart Required: Yes
Instructions:
1. Download Critical Patch Update from Oracle Support. 2. Apply patch to Oracle Agile PLM 9.3.6. 3. Restart PLM services. 4. Verify patch application.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict HTTP access to Oracle Agile PLM Export component to trusted IP addresses only
Privilege Reduction
allReview and minimize low privileged accounts with access to Export functionality
🧯 If You Can't Patch
- Isolate Oracle Agile PLM system in separate network segment with strict firewall rules
- Implement application-level monitoring for suspicious deserialization attempts
🔍 How to Verify
Check if Vulnerable:
Check Oracle Agile PLM version and verify if January 2024 Critical Patch Update is appliedCheck Version:
Check Oracle Agile PLM administration console or configuration files for version informationVerify Fix Applied:
Confirm patch version from Oracle Support and verify no deserialization vulnerabilities in Export component📡 Detection & Monitoring
Log Indicators:
