CVE-2024-28793
📋 TL;DR
IBM Engineering Workflow Management versions 7.0.2 and 7.0.3 contain a stored cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious JavaScript into the web interface. This could lead to session hijacking or credential theft when other users view the compromised content. Organizations using these specific versions with vulnerable configurations are affected.
💻 Affected Systems
- IBM Engineering Workflow Management
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, compromise user sessions, and gain unauthorized access to sensitive engineering workflow data and systems.
Likely Case
Authenticated malicious users could embed scripts to steal session cookies or credentials from other users viewing the same content, leading to account compromise.
If Mitigated
With proper input validation and output encoding, the risk is limited to authenticated users with content creation privileges in specific configurations.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of vulnerable configuration scenarios. The vulnerability is well-documented but no public exploit code has been identified.
🛠️ 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/7154955
Restart Required: Yes
Instructions:
1. Review IBM advisory at the provided URL. 2. Apply the recommended interim fix or security patch. 3. Restart the IBM Engineering Workflow Management service. 4. Verify the fix by testing XSS payloads in previously vulnerable areas.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement additional input validation and output encoding for user-supplied content in the web interface
Content Security Policy
allImplement strict Content Security Policy headers to limit script execution
🧯 If You Can't Patch
- Implement web application firewall rules to detect and block XSS payloads
- Restrict user permissions to limit who can create or modify content in vulnerable areas
🔍 How to Verify
Check if Vulnerable:
Check if running IBM Engineering Workflow Management version 7.0.2 or 7.0.3 and review configuration for unsanitized user input handlingCheck Version:
Check application version through IBM Engineering Workflow Management administration interface or installation directoryVerify Fix Applied:
Test XSS payloads in user input fields and verify they are properly sanitized or blocked📡 Detection & Monitoring
Log Indicators:
- Unusual JavaScript patterns in user input logs
- Multiple failed XSS attempts in web server logs
Network Indicators:
- Suspicious script tags or JavaScript in HTTP POST requests to content creation endpoints
SIEM Query:
