CVE-2024-10033
📋 TL;DR
A cross-site scripting (XSS) vulnerability exists in aap-gateway that allows attackers to inject malicious scripts via the '?next=' URL parameter. This can lead to session hijacking, data theft, and unauthorized actions performed on behalf of users. Organizations using vulnerable versions of aap-gateway are affected.
💻 Affected Systems
- aap-gateway
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover, sensitive data exfiltration, and persistent compromise of user sessions leading to unauthorized administrative actions.
Likely Case
Session hijacking, credential theft, and injection of malicious content that could lead to further exploitation.
If Mitigated
Limited impact with proper input validation and output encoding, potentially only affecting specific user sessions.
🎯 Exploit Status
XSS vulnerabilities typically have low exploitation complexity; this specific vector uses URL parameters which are commonly accessible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat Security Advisory RHSA-2024:8534 for specific patched versions
Vendor Advisory: https://access.redhat.com/errata/RHSA-2024:8534
Restart Required: Yes
Instructions:
1. Review Red Hat advisory RHSA-2024:8534. 2. Update aap-gateway to the patched version specified in the advisory. 3. Restart the gateway service. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to sanitize the 'next' parameter before processing
# Configure web application firewall or gateway rules to filter malicious 'next' parameter values
# Implement input validation in application code: validate and sanitize all URL parameters
Content Security Policy
allImplement CSP headers to restrict script execution from untrusted sources
# Add to web server configuration: Content-Security-Policy: default-src 'self'
# Implement CSP with strict directives to prevent inline script execution
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block malicious '?next=' parameter patterns
- Disable or restrict functionality that uses the 'next' parameter if not essential
🔍 How to Verify
Check if Vulnerable:
Test if the application processes '?next=' parameter without proper sanitization by attempting safe payload injection
Check Version:
rpm -q aap-gateway
Verify Fix Applied:
After patching, test that malicious '?next=' parameter values are properly sanitized or rejected
📡 Detection & Monitoring
Log Indicators:
- Unusual '?next=' parameter values in access logs
- Multiple failed attempts with script-like content in URL parameters
Network Indicators:
- HTTP requests containing script tags or JavaScript in 'next' parameter
- Unusual redirect patterns from gateway endpoints
SIEM Query:
source="web_access_logs" AND uri="*?next=*javascript:*" OR uri="*?next=*<script>*"
