Source Code Disclosure in IBM WebSphere Application Server via Invalid Host Header

IdentifiersCVE-2005-1112CWE-200

A vulnerability in IBM WebSphere Application Server 6.0 and earlier allows remote attackers to obtain the source code of Java Server Pages (.jsp) files. This occurs when the document root of the web server is shared and an HTTP request is made with an invalid Host header. The malformed request causes the web server to serve the raw JSP source code instead of passing the request to the JSP engine for processing.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Attackers can retrieve the source code of JSP files, potentially exposing sensitive information such as credentials, business logic, or other exploitable details. This can lead to further attacks, including privilege escalation, information disclosure, or remote code execution if the source code contains additional vulnerabilities.

Mitigation

If you can’t patch tonight, do this now.

As an immediate mitigation, restrict direct access to the document root and ensure that the web server is configured to deny requests with invalid Host headers. Implement network-level controls to limit access to the web server and monitor for suspicious requests that may indicate exploitation attempts.

Remediation

Patch, then assume compromise.

Upgrade to a fixed version of IBM WebSphere Application Server where this issue is addressed. Ensure that the web server and application server are properly configured so that requests for .jsp files are always handled by the JSP engine, regardless of the Host header. Avoid sharing the document root between the web server and the application server.
