CVE-2024-28772
📋 TL;DR
IBM Security Directory Integrator 7.2.0 and IBM Security Verify Directory Integrator 10.0.0 contain a stored cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious JavaScript into the web interface. This could enable attackers to steal credentials or perform unauthorized actions within trusted user sessions. Organizations using these specific versions of IBM's directory integration products are affected.
💻 Affected Systems
- IBM Security Directory Integrator
- IBM Security Verify Directory Integrator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, gain full control of the system, and potentially pivot to connected directory services and applications.
Likely Case
Authenticated users could embed malicious scripts that steal session cookies or credentials from other users accessing the compromised interface.
If Mitigated
With proper input validation and output encoding, the risk is limited to authenticated users who would need to bypass additional security controls.
🎯 Exploit Status
Exploitation requires authenticated access to the web interface. The vulnerability is in the stored XSS mechanism, making it persistent across sessions.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply interim fix or upgrade as specified in IBM advisory
Vendor Advisory: https://www.ibm.com/support/pages/node/7161448
Restart Required: Yes
Instructions:
1. Review IBM advisory at the provided URL. 2. Apply the recommended interim fix or upgrade to a patched version. 3. Restart the affected services. 4. Verify the fix by testing XSS payloads.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement additional input validation and output encoding for user-supplied content in the web UI
Content Security Policy
allImplement strict Content Security Policy headers to limit script execution
🧯 If You Can't Patch
- Restrict access to the web UI to only trusted, authenticated users with minimal privileges
- Implement web application firewall rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check if running IBM Security Directory Integrator 7.2.0 or IBM Security Verify Directory Integrator 10.0.0. Test by attempting to inject basic XSS payloads into web UI input fields.Check Version:
Check product documentation or administrative interface for version informationVerify Fix Applied:
After applying patches, test with XSS payloads to ensure they are properly sanitized and do not execute. Verify version is no longer vulnerable.📡 Detection & Monitoring
Log Indicators:
- Unusual JavaScript or script-like content in user input fields
- Multiple failed login attempts followed by successful authentication
Network Indicators:
- Suspicious outbound connections from the server after user interaction with the web UI
