CVE-2024-46910
📋 TL;DR
An authenticated user in Apache Atlas can inject malicious scripts (XSS) that execute in other users' browsers, potentially allowing impersonation of those users. This affects Apache Atlas versions 2.3.0 and earlier where users have authenticated access.
💻 Affected Systems
- Apache Atlas
📦 What is this software?
Atlas by Apache
⚠️ Risk & Real-World Impact
Worst Case
An attacker could fully impersonate another user, gaining their privileges, accessing sensitive data, or performing unauthorized actions as that user.
Likely Case
An attacker steals session tokens or credentials via XSS, leading to unauthorized access to the victim's account.
If Mitigated
With input validation and output encoding controls, the XSS payloads would be neutralized, preventing exploitation.
🎯 Exploit Status
Exploitation requires authenticated access and user interaction (e.g., victim viewing malicious content).
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.4.0
Vendor Advisory: https://lists.apache.org/thread/sqzp34l4cdk21zoq5g31qlsvr7jvb1fy
Restart Required: No
Instructions:
1. Download Apache Atlas version 2.4.0 from the official Apache website. 2. Replace the existing installation with the new version. 3. Verify the upgrade by checking the version number.
🔧 Temporary Workarounds
Implement Content Security Policy (CSP)
allDeploy a strict CSP header to mitigate XSS by restricting script execution sources.
Add 'Content-Security-Policy' header with appropriate directives in web server configuration.
🧯 If You Can't Patch
- Restrict user access to only trusted, authenticated users and monitor for suspicious activity.
- Deploy a web application firewall (WAF) with XSS protection rules enabled.
🔍 How to Verify
Check if Vulnerable:
Check the Apache Atlas version; if it is 2.3.0 or earlier, it is vulnerable.Check Version:
Check the version in the Apache Atlas web interface or configuration files.Verify Fix Applied:
Confirm the version is 2.4.0 or later and test for XSS vulnerabilities via security scanning.📡 Detection & Monitoring
Log Indicators:
- Unusual user activity, such as login from unexpected locations or privilege escalation attempts.
Network Indicators:
- HTTP requests containing suspicious script tags or encoded payloads in parameters.
SIEM Query:
Search for web logs with patterns like '<script>', 'javascript:', or encoded characters in URL parameters.
