CVE-2024-11005
📋 TL;DR
This CVE describes a command injection vulnerability in Ivanti Connect Secure and Policy Secure that allows authenticated administrators to execute arbitrary commands on the underlying system. Attackers with admin privileges can achieve remote code execution, potentially compromising the entire appliance. Only versions before 22.7R2.1 (Connect Secure) and 22.7R1.1 (Policy Secure) are affected, with 9.1Rx versions being exempt.
💻 Affected Systems
- Ivanti Connect Secure
- Ivanti Policy Secure
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the Ivanti appliance leading to lateral movement into internal networks, data exfiltration, and persistent backdoor installation.
Likely Case
Attackers with stolen admin credentials or compromised admin accounts gain full control of the appliance to intercept traffic, modify configurations, or deploy malware.
If Mitigated
With proper access controls, network segmentation, and monitoring, impact is limited to the appliance itself without lateral movement.
🎯 Exploit Status
Exploitation requires admin credentials but is straightforward once obtained. CVSS 9.1 indicates high severity.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 22.7R2.1 for Connect Secure, 22.7R1.1 for Policy Secure
