CVE-2025-55139
📋 TL;DR
This CVE describes a Server-Side Request Forgery (SSRF) vulnerability in multiple Ivanti security products that allows authenticated administrators to enumerate internal services. Attackers with admin privileges can make the vulnerable system send requests to internal network resources, potentially discovering sensitive services. This affects Ivanti Connect Secure, Policy Secure, ZTA Gateway, and Neurons for Secure Access before specific patched versions.
💻 Affected Systems
- Ivanti Connect Secure
- Ivanti Policy Secure
- Ivanti ZTA Gateway
- Ivanti Neurons for Secure Access
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker with compromised admin credentials could map the entire internal network, discover sensitive services (databases, management interfaces, internal APIs), and potentially chain this with other vulnerabilities for lateral movement or data exfiltration.
Likely Case
Malicious insiders or attackers with stolen admin credentials will use this to discover internal services for reconnaissance, potentially identifying additional attack targets within the network.
If Mitigated
With proper network segmentation and admin credential protection, impact is limited to service enumeration within accessible network segments only.
🎯 Exploit Status
Requires admin credentials. Exploitation involves crafting SSRF requests to enumerate internal services.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Connect Secure 22.7R2.9 or 22.8R2, Policy Secure 22.7R1.6, ZTA Gateway 2.8R2.3-723, Neurons for Secure Access 22.8R1.4
Restart Required: No
Instructions:
1. Log into Ivanti support portal. 2. Download appropriate patch for your product version. 3. Apply patch according to Ivanti documentation. 4. Verify patch installation.
🔧 Temporary Workarounds
Restrict Admin Access
allLimit admin access to only trusted personnel and implement multi-factor authentication for all admin accounts.
Network Segmentation
allImplement strict network segmentation to limit what internal services the vulnerable systems can reach.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable systems from sensitive internal services
- Enforce strong authentication and monitoring for all admin accounts, implement just-in-time admin access
🔍 How to Verify
Check if Vulnerable:
Check product version in admin interface against affected versions list. If version is earlier than patched versions, system is vulnerable.Check Version:
Check via product admin interface or CLI: show version (product-specific)Verify Fix Applied:
Verify version shows patched version in admin interface. Test SSRF functionality is no longer exploitable.📡 Detection & Monitoring
Log Indicators:
- Unusual admin login patterns
- Multiple HTTP requests to internal IP ranges from admin accounts
- Failed connection attempts to internal services
Network Indicators:
- Unusual outbound connections from Ivanti systems to internal services
- Port scanning patterns originating from Ivanti systems
