CVE-2024-39710
📋 TL;DR
This vulnerability allows authenticated administrators to inject malicious arguments into Ivanti Connect Secure and Policy Secure systems, leading to remote code execution. Attackers with admin credentials can execute arbitrary commands on affected appliances. Organizations using vulnerable versions of these Ivanti products are at risk.
💻 Affected Systems
- Ivanti Connect Secure
- Ivanti Policy Secure
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to install persistent backdoors, steal sensitive data, pivot to internal networks, and disrupt critical VPN/access services.
Likely Case
Attackers with stolen or compromised admin credentials gain full control of affected appliances, enabling data exfiltration, credential harvesting, and lateral movement.
If Mitigated
With proper credential protection and network segmentation, impact is limited to the affected appliance with minimal lateral movement potential.
🎯 Exploit Status
Exploitation requires admin credentials but is straightforward once credentials are obtained. Similar vulnerabilities in Ivanti products have been actively exploited in the wild.
