CVE-2025-11622
📋 TL;DR
This vulnerability allows a local authenticated attacker to exploit insecure deserialization in Ivanti Endpoint Manager to escalate their privileges. Attackers with existing local access can gain higher privileges on the system. Organizations using Ivanti Endpoint Manager versions before 2024 SU4 are affected.
💻 Affected Systems
- Ivanti Endpoint Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with administrative privileges, enabling lateral movement, data exfiltration, and persistence mechanisms installation.
Likely Case
Local privilege escalation allowing attackers to bypass security controls, access sensitive data, and execute arbitrary code with elevated permissions.
If Mitigated
Limited impact if proper access controls, network segmentation, and monitoring are in place to detect and contain privilege escalation attempts.
🎯 Exploit Status
Exploitation requires understanding of deserialization attacks and local system access. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2024 SU4 or later
Vendor Advisory: https://forums.ivanti.com/s/article/Security-Advisory-Ivanti-Endpoint-Manager-EPM-October-2025
Restart Required: Yes
Instructions:
1. Download Ivanti Endpoint Manager 2024 SU4 or later from the Ivanti portal. 2. Backup current configuration and data. 3. Run the installer with administrative privileges. 4. Restart the EPM services and affected systems.
🔧 Temporary Workarounds
Restrict Local Access
allLimit local user accounts and implement strict access controls to reduce attack surface
Application Whitelisting
windowsImplement application control policies to prevent unauthorized code execution
🧯 If You Can't Patch
- Implement strict principle of least privilege for all user accounts
- Deploy enhanced monitoring for privilege escalation attempts and unusual process activity
