CVE-2024-52363
📋 TL;DR
IBM InfoSphere Information Server 11.7 contains a directory traversal vulnerability that allows remote attackers to read arbitrary files on the system by sending specially crafted URL requests containing directory traversal sequences. This affects organizations running vulnerable versions of IBM InfoSphere Information Server without proper security controls.
💻 Affected Systems
- IBM InfoSphere Information Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could read sensitive system files, configuration files, or application data, potentially leading to credential theft, data exfiltration, or further system compromise.
Likely Case
Attackers could access configuration files, log files, or other sensitive information that could be used for reconnaissance or to facilitate other attacks.
If Mitigated
With proper network segmentation and access controls, impact would be limited to files accessible by the application service account.
🎯 Exploit Status
Directory traversal attacks are well-understood and typically easy to execute with basic HTTP tools.

Web Application Firewall (WAF)
allConfigure WAF rules to block directory traversal patterns in URLs
Network Segmentation
allRestrict network access to InfoSphere Information Server to only trusted sources
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure
- Monitor logs for directory traversal attempts and investigate any suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check if running IBM InfoSphere Information Server 11.7 without the security fix appliedCheck Version:
Check product version through InfoSphere Information Server administration console or installation logsVerify Fix Applied:
Verify the fix version is installed and test with controlled directory traversal attempts📡 Detection & Monitoring
Log Indicators:
