CVE-2024-28795
📋 TL;DR
IBM InfoSphere Information Server 11.7 contains a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious JavaScript into the web interface. This could lead to session hijacking or credential theft when users interact with compromised pages. Organizations running IBM InfoSphere Information Server 11.7 are affected.
💻 Affected Systems
- IBM InfoSphere Information Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers steal administrator credentials, gain full system access, and exfiltrate sensitive data from the information server.
Likely Case
Attackers steal user session cookies or credentials, enabling unauthorized access to the InfoSphere Information Server with the victim's privileges.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before execution, preventing exploitation.
🎯 Exploit Status
XSS vulnerabilities typically require user interaction (clicking a malicious link) but are straightforward to exploit once discovered.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply fix pack 11.7.1.4 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/7158408
Restart Required: Yes
Instructions:
1. Download the latest fix pack from IBM Fix Central. 2. Follow IBM's installation guide for InfoSphere Information Server 11.7 fix packs. 3. Apply the fix pack to all affected servers. 4. Restart the InfoSphere Information Server services.
🔧 Temporary Workarounds
Implement Web Application Firewall (WAF)
allDeploy a WAF with XSS protection rules to filter malicious input before it reaches the application.
Content Security Policy (CSP)
allImplement a strict CSP header to restrict script execution sources and prevent inline script execution.
🧯 If You Can't Patch
- Restrict network access to the InfoSphere Information Server web interface to trusted IP addresses only.
- Educate users about phishing risks and safe browsing practices to reduce the likelihood of clicking malicious links.
🔍 How to Verify
Check if Vulnerable:
Check the installed version of IBM InfoSphere Information Server. If it's version 11.7 without fix pack 11.7.1.4 or later, it's vulnerable.Check Version:
Check the version via the InfoSphere Information Server web interface under Help > About, or examine installation logs.Verify Fix Applied:
Verify that fix pack 11.7.1.4 or later is installed by checking the version in the InfoSphere Information Server administration console.📡 Detection & Monitoring
