CVE-2024-21088
📋 TL;DR
This vulnerability in Oracle Production Scheduling's Import Utility allows unauthenticated attackers with network access via HTTP to compromise data integrity. Attackers can create, delete, or modify critical data within Oracle Production Scheduling. Organizations running Oracle E-Business Suite versions 12.2.4 through 12.2.12 are affected.
💻 Affected Systems
- Oracle E-Business Suite - Production Scheduling
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of Oracle Production Scheduling data integrity, allowing attackers to manipulate scheduling data, production plans, and critical business operations data without authentication.
Likely Case
Unauthorized modification or deletion of production scheduling data, potentially disrupting manufacturing operations, supply chain planning, and business processes.
If Mitigated
Limited impact if proper network segmentation and access controls prevent unauthenticated HTTP access to the vulnerable component.
🎯 Exploit Status
CVSS indicates low attack complexity and no authentication required, making exploitation straightforward for attackers with network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply Oracle Critical Patch Update for April 2024
Vendor Advisory: https://www.oracle.com/security-alerts/cpuapr2024.html
Restart Required: Yes
Instructions:
1. Download the appropriate patch from Oracle Support. 2. Apply the patch following Oracle's patching procedures. 3. Restart affected services. 4. Verify the patch application.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to Oracle Production Scheduling services to only trusted internal networks
Configure firewall rules to block external HTTP access to Oracle E-Business Suite ports
Access Control Lists
allImplement network ACLs to limit which IP addresses can access the vulnerable Import Utility
Use network firewalls or load balancers to restrict access to specific source IP ranges
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Oracle Production Scheduling from untrusted networks
- Deploy web application firewall (WAF) rules to monitor and block suspicious HTTP requests to the Import Utility
🔍 How to Verify
Check if Vulnerable:
Check Oracle E-Business Suite version and verify if Production Scheduling component is installed and accessible via HTTP
Check Version:
Check Oracle application version through administrative interfaces or database queries specific to your E-Business Suite implementation
Verify Fix Applied:
Verify patch application through Oracle's patch verification tools and confirm the April 2024 CPU has been applied
