CVE-2024-13830
📋 TL;DR
This reflected cross-site scripting (XSS) vulnerability in Ivanti Connect Secure and Policy Secure allows remote unauthenticated attackers to execute malicious scripts in victims' browsers. When exploited, it can lead to admin privilege escalation, though user interaction (like clicking a malicious link) is required. Organizations using affected Ivanti products are at risk.
💻 Affected Systems
- Ivanti Connect Secure
- Ivanti Policy Secure
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative control over Ivanti appliances, potentially compromising entire network security infrastructure, exfiltrating credentials, and pivoting to internal networks.
Likely Case
Attackers craft malicious links to steal admin session cookies or credentials when administrators click them, leading to unauthorized access to the Ivanti management interface.
If Mitigated
With proper web application firewalls and user awareness training, exploitation attempts are blocked or users avoid clicking malicious links, limiting impact.
🎯 Exploit Status
Reflected XSS vulnerabilities typically have low exploitation complexity. The requirement for user interaction reduces automatic exploitation but social engineering can overcome this.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Connect Secure 22.7R2.6, Policy Secure 22.7R1.3
Restart Required: Yes
Instructions:
1. Download the latest firmware from Ivanti support portal. 2. Backup current configuration. 3. Apply the firmware update through the admin interface. 4. Reboot the appliance. 5. Verify the update was successful.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with XSS protection rules to block malicious payloads before they reach the Ivanti appliance.
Input Validation Rules
allConfigure the Ivanti appliance to sanitize or reject suspicious input patterns in affected parameters.
🧯 If You Can't Patch
- Implement strict network segmentation to limit access to Ivanti management interfaces to trusted IP addresses only.
- Enable Content Security Policy (CSP) headers to mitigate XSS impact and conduct user awareness training about phishing risks.
🔍 How to Verify
Check if Vulnerable:
Check the appliance version in the admin interface under System > Maintenance > Version Information.Check Version:
No CLI command available; check via web admin interface at https://<appliance-ip>/adminVerify Fix Applied:
Verify the version number matches or exceeds the patched versions: Connect Secure 22.7R2.6 or Policy Secure 22.7R1.3.📡 Detection & Monitoring
