CVE-2024-39725 Overview
CVE-2024-39725 affects IBM Engineering Lifecycle Optimization - Engineering Insights versions 7.0.2 and 7.0.3. The application returns detailed technical error messages directly to the browser. Remote attackers can trigger these errors to harvest sensitive information about the application stack, file paths, or internal configuration. Attackers use the disclosed data to plan follow-on attacks against the system. The issue maps to [CWE-209] (Generation of Error Message Containing Sensitive Information).
Critical Impact
Unauthenticated remote attackers can obtain sensitive technical details from verbose error messages, enabling reconnaissance for subsequent attacks.
Affected Products
- IBM Engineering Lifecycle Optimization - Engineering Insights 7.0.2
- IBM Engineering Lifecycle Optimization - Engineering Insights 7.0.3
- Deployments exposing the Engineering Insights web interface over the network

Technical Details for CVE-2024-39725
Vulnerability Analysis
The vulnerability is an information disclosure flaw in IBM Engineering Lifecycle Optimization - Engineering Insights. When the application encounters an unhandled exception or malformed request, it returns a detailed technical error message to the requesting browser. These messages can include stack traces, internal file paths, class names, database identifiers, or component version numbers.
An unauthenticated remote attacker can send crafted HTTP requests to trigger error conditions. The returned content aids attackers in fingerprinting the deployment and identifying additional weaknesses. Although the flaw does not directly compromise integrity or availability, the disclosed data lowers the barrier for chained exploitation against the Jazz-based reporting environment.
Root Cause
The root cause is improper error handling in the Engineering Insights web tier. Exception paths propagate raw diagnostic output to HTTP responses instead of returning generic, sanitized error pages. This behavior corresponds to [CWE-209], where verbose messages intended for developers reach untrusted clients in production configurations.
Attack Vector
Exploitation requires only network access to the Engineering Insights endpoint. No authentication or user interaction is needed. The attacker submits malformed parameters, invalid query syntax, or requests to unexpected resources. The server responds with detailed error content that the attacker parses for reusable intelligence. See the IBM Support Page for vendor-confirmed technical details.
Detection Methods for CVE-2024-39725
Indicators of Compromise
- HTTP responses from Engineering Insights containing Java stack traces, class names, or file system paths returned to external clients.
- Repeated 4xx or 5xx responses from a single source IP against Engineering Insights URLs within short time windows.
- Unusual query strings or malformed parameters targeting reporting or dashboard endpoints.
Detection Strategies
- Inspect web server and reverse proxy logs for responses containing keywords such as Exception, at com.ibm, Caused by, or absolute file paths.
- Deploy web application firewall rules that flag outbound responses containing stack trace patterns from Engineering Insights hosts.
- Correlate error-response spikes with source IP reputation data to identify reconnaissance activity.
Monitoring Recommendations
- Forward Engineering Insights application and HTTP logs to a centralized SIEM for long-term pattern analysis.
- Alert on any HTTP 500 response body exceeding a defined size threshold from Engineering Insights hosts.
- Track access to non-standard URLs and parameter tampering attempts against the Engineering Insights service.
How to Mitigate CVE-2024-39725
Immediate Actions Required
- Apply the fix referenced in the IBM Support Page for Engineering Insights 7.0.2 and 7.0.3.
- Restrict network access to Engineering Insights to trusted internal networks and authenticated VPN users.
- Review recent web server logs for evidence of error-based reconnaissance and rotate any credentials or paths that may have been disclosed.
Patch Information
IBM has published remediation guidance on the IBM Support Page. Administrators should upgrade or apply the vendor-supplied interim fix for versions 7.0.2 and 7.0.3. Confirm the fix by verifying that error responses no longer include stack traces or internal path information.
Workarounds
- Configure the application server or reverse proxy to replace detailed error pages with generic HTTP 500 responses before the fix is applied.
- Disable debug and verbose logging modes in production Engineering Insights deployments.
- Place a web application firewall in front of Engineering Insights and enforce response inspection rules that strip stack trace content.
