CVE-2025-55147
📋 TL;DR
This CVE describes a Cross-Site Request Forgery (CSRF) vulnerability in multiple Ivanti security products that allows an unauthenticated remote attacker to trick authenticated users into performing sensitive actions without their knowledge. Attackers can exploit this by luring victims to malicious websites while logged into affected Ivanti systems. Organizations using vulnerable versions of Ivanti Connect Secure, Policy Secure, ZTA Gateway, or Neurons for Secure Access are affected.
💻 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
Attackers could perform administrative actions like creating new privileged accounts, changing configurations, or accessing sensitive data through authenticated user sessions, potentially leading to full system compromise.
Likely Case
Attackers trick users into performing unauthorized actions such as changing passwords, modifying access policies, or leaking session information, leading to privilege escalation or data exposure.
If Mitigated
With proper CSRF protections and user awareness, exploitation attempts would fail or be detected, limiting impact to isolated incidents.
🎯 Exploit Status
CSRF attacks are generally low complexity. Exploitation requires social engineering to lure authenticated users to malicious sites.

🔧 Temporary Workarounds
CSRF Token Implementation
allImplement anti-CSRF tokens in web application forms if not already present
SameSite Cookie Attribute
allConfigure session cookies with SameSite=Strict or SameSite=Lax attributes
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to detect CSRF patterns
- Educate users about phishing risks and safe browsing practices
🔍 How to Verify
Check if Vulnerable:
Check product version via web admin interface or CLI. Compare against affected versions listed in advisory.Check Version:
ssh admin@<device-ip> show versionVerify Fix Applied:
Verify installed version matches or exceeds patched versions. Test CSRF protection by attempting to submit forms without valid tokens.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts from same IP
- Unexpected configuration changes by non-admin users
- Sensitive actions performed without proper authentication logs
Network Indicators:
- Requests missing CSRF tokens
- Cross-origin requests to sensitive endpoints
- Suspicious referrer headers
