CVE-2025-50064
📋 TL;DR
This vulnerability in Oracle WebLogic Server allows authenticated high-privileged attackers to modify or read limited data through HTTP requests requiring user interaction. It affects WebLogic Server versions 12.2.1.4.0, 14.1.1.0.0, and 14.1.2.0.0. The attack scope can extend beyond WebLogic to impact other connected systems.
💻 Affected Systems
- Oracle WebLogic Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Privileged attacker gains unauthorized data access and modification across multiple connected systems, potentially leading to data corruption or exposure of sensitive information.
Likely Case
Authenticated administrator or high-privilege user exploits the vulnerability to manipulate WebLogic configuration or application data, potentially affecting dependent applications.
If Mitigated
Limited impact with proper access controls, network segmentation, and user interaction restrictions in place.
🎯 Exploit Status
Exploitation requires high privileges and user interaction, but is described as 'easily exploitable' by Oracle.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply patches from Oracle Critical Patch Update July 2025

Restart Required: Yes
Instructions:
1. Download appropriate patches from Oracle Support. 2. Apply patches following Oracle's WebLogic patching procedures. 3. Restart WebLogic Server instances. 4. Verify patch application.
🔧 Temporary Workarounds
Restrict Network Access
allLimit HTTP access to WebLogic Server to trusted networks only
Configure firewall rules to restrict access to WebLogic ports (typically 7001, 7002)
Implement Least Privilege
allReview and reduce administrative privileges to minimum necessary
Review WebLogic security roles and policies
Remove unnecessary administrative access
🧯 If You Can't Patch
- Implement strict network segmentation to isolate WebLogic servers
- Enforce multi-factor authentication for administrative access
