CVE-2024-52888
📋 TL;DR
This CVE describes a cross-site scripting (XSS) vulnerability in a Check Point portal where authenticated users can execute scripts when viewing directory or file properties. The vulnerability allows attackers to inject malicious scripts that execute in victims' browsers. Only authenticated users are affected, but this could lead to session hijacking or credential theft.
💻 Affected Systems
- Check Point Security Management Portal

⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal authenticated session cookies, perform actions as the victim user, access sensitive data, or redirect to malicious sites.
Likely Case
Attackers could perform session hijacking, steal credentials, or deface portal pages through script injection.
If Mitigated
With proper input validation and output encoding, the risk is limited to minor UI disruption with no data compromise.
🎯 Exploit Status
Exploitation requires authenticated access; typical XSS payloads would work
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Point Security Gateway R81.20.40, R81.10.90, and later versions
Vendor Advisory: https://support.checkpoint.com/results/sk/sk183055
Restart Required: Yes
Instructions:
1. Log into Check Point Security Management Server. 2. Navigate to Software Updates. 3. Install the recommended Jumbo Hotfix Accumulator. 4. Apply policy and restart services as required.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement additional input validation for directory and file property display functions
Configuration through Check Point management interface; no direct commands
Content Security Policy
allImplement strict Content Security Policy headers to mitigate XSS impact
Add CSP headers via web server configuration or application settings
🧯 If You Can't Patch
- Restrict portal access to trusted users only using network segmentation
- Implement web application firewall rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check current version against patched versions; test for XSS in directory/file property displayCheck Version:
fw ver | grep "This is Check Point"Verify Fix Applied:
Verify installed version is R81.20.40, R81.10.90 or later; test XSS payloads no longer execute📡 Detection & Monitoring
Log Indicators:
- Unusual script tags in portal access logs
- Multiple failed authentication attempts followed by successful login
Network Indicators:
- HTTP requests containing script payloads to portal endpoints
- Unusual outbound connections from portal server
