1. Introduction
IBM Rational RequisitePro ReqWebHelp Multiple XSS is a cross-site scripting vulnerability affecting the web server hosting JSP scripts for this product. This allows an attacker to inject malicious code into webpages viewed by users, potentially stealing credentials or performing actions on their behalf. Affected systems are typically those running IBM Rational RequisitePro with the vulnerable help engine installed. A successful exploit could compromise confidentiality, integrity and availability of user data and system functionality.
2. Technical Explanation
The vulnerability occurs because IBM Rational RequisitePro fails to properly sanitize input received from users via the ‘searchWord’, ‘maxHits’, ‘scopedSearch’, ‘scope’ parameters of ‘searchView.jsp’ and the ‘operation’ parameter of ‘workingSet.jsp’. This allows an attacker to inject arbitrary HTML or script code into a user’s browser, which will then be executed within the security context of that user. The vulnerability is exploitable remotely without authentication. CVE-2009-3730 has been assigned to this issue.
- Root cause: Missing input validation on several parameters used in dynamic HTML generation.
- Exploit mechanism: An attacker crafts a malicious URL containing XSS payloads within the vulnerable parameters, which are then rendered by the web server and executed in the victim’s browser. For example, an attacker could inject JavaScript code into the ‘searchWord’ parameter to redirect users to a phishing site.
- Scope: IBM Rational RequisitePro installations using the affected JSP scripts.
3. Detection and Assessment
To confirm vulnerability, check the version of IBM Rational RequisitePro installed and verify if it uses the vulnerable help engine. A thorough assessment involves attempting to inject XSS payloads into the affected parameters.
- Quick checks: Check the product version via the IBM Rational RequisitePro user interface or by examining installation directories.
- Scanning: Nessus plugin ID 36721 can be used as an example for detecting this vulnerability.
- Logs and evidence: Examine web server logs for suspicious requests containing XSS payloads targeting ‘searchView.jsp’ and ‘workingSet.jsp’.

4. Solution / Remediation Steps
The recommended solution is to contact the vendor for an updated help engine that addresses these XSS vulnerabilities. A new help engine is reportedly available.
4.1 Preparation
- Ensure you have access to the vendor’s support resources and download links for the new help engine. A roll back plan involves restoring from the backup if the update fails or causes issues.
- A change window may be required depending on your environment and service level agreements. Approval from relevant IT stakeholders might be necessary.
4.2 Implementation
- Step 1: Download the updated help engine package from the IBM support website.
- Step 2: Stop all IBM Rational RequisitePro related services.
- Step 3: Replace the existing vulnerable JSP scripts with the files provided in the new help engine package.
- Step 4: Restart all IBM Rational RequisitePro related services.
4.3 Config or Code Example
Before
# No specific code example available as this involves replacing JSP scripts with updated versions from the vendor. The vulnerable scripts are 'searchView.jsp' and 'workingSet.jsp'.After
# After updating, ensure that the new version of 'searchView.jsp' and 'workingSet.jsp' do not contain the XSS vulnerabilities. Verify this through testing (see section 5).4.4 Security Practices Relevant to This Vulnerability
Several security practices can help prevent similar issues. Input validation is crucial for blocking malicious data, while least privilege reduces the impact if an attack succeeds. Patch cadence ensures timely updates and addresses known vulnerabilities. Safe defaults minimize the risk of misconfiguration.
- Practice 1: Implement strict input validation on all user-supplied data to prevent XSS attacks.
- Practice 2: Apply a regular patch management process to ensure that IBM Rational RequisitePro is updated with the latest security fixes.
4.5 Automation (Optional)
Automation scripts are not directly applicable for this specific vulnerability as it requires replacing files and restarting services, which typically involves manual intervention or vendor-specific tools.
# No automation script available due to the nature of the fix.5. Verification / Validation
- Post-fix check: Access ‘searchView.jsp’ and ‘workingSet.jsp’ through a web browser and attempt to inject an XSS payload (e.g., <script>alert(‘XSS’)</script>) into the ‘searchWord’, ‘maxHits’, ‘scopedSearch’, ‘scope’, and ‘operation’ parameters. The payload should not execute.
- Re-test: Repeat the detection steps from section 3 to confirm that the vulnerability is no longer present.
- Monitoring: Monitor web server logs for any suspicious requests containing XSS payloads targeting ‘searchView.jsp’ and ‘workingSet.jsp’.
# Post-fix command and expected output: Accessing searchView.jsp with a payload should not result in JavaScript execution; the payload should be displayed as text.6. Preventive Measures and Monitoring
Update security baselines to include this vulnerability and its remediation steps. Implement static application security testing (SAST) during development to identify similar input validation issues early on. A sensible patch review cycle helps address known vulnerabilities promptly.
- Baselines: Update your security baseline or policy to reflect the need for regular patching of IBM Rational RequisitePro and secure coding practices.
- Pipelines: Add SAST checks in your CI/CD pipeline to identify potential XSS vulnerabilities during development.
- Asset and patch process: Establish a quarterly review cycle for identifying and applying security patches to all systems, including IBM Rational RequisitePro.
7. Risks, Side Effects, and Roll Back
- Risk or side effect 2: Service interruption during the update process. Mitigation: Schedule the update during a maintenance window and communicate downtime to users.
- Roll back: 1) Stop all IBM Rational RequisitePro related services. 2) Restore the original ‘searchView.jsp’ and ‘workingSet.jsp’ files from the backup. 3) Restart all IBM Rational RequisitePro related services.
