1. Introduction
The ManageEngine ADAudit Plus ‘reportList’ parameter is vulnerable to a cross-site scripting (XSS) attack. This allows an attacker to inject malicious scripts into web pages viewed by users of the affected system, potentially leading to session hijacking, data theft, or unauthorized actions. Systems running vulnerable versions of ADAudit Plus are at risk. A successful exploit could compromise confidentiality, integrity, and availability of user sessions and associated data.
2. Technical Explanation
- Root cause: Missing input validation on the ‘reportList’ parameter allows arbitrary HTML and JavaScript to be included in generated reports.
- Exploit mechanism: An attacker crafts a URL with malicious script code in the ‘reportList’ parameter, then tricks a user into visiting it. For example:
https://[ADAudit Plus server]/jsp/audit/reports/ExportReport.jsp?reportList= - Scope: ManageEngine ADAudit Plus versions affected are not explicitly specified in the available information, but CVE-2010-2049 should be investigated for specific version details.
3. Detection and Assessment
To confirm vulnerability, check the installed ADAudit Plus version and review request logs for unsanitized input to the ‘reportList’ parameter.
- Quick checks: Access the ADAudit Plus web interface and navigate to Help > About to determine the product version.
- Scanning: Nessus vulnerability ID 59876 may detect this issue, but results should be verified manually.
- Logs and evidence: Examine web server logs for requests containing script tags within the ‘reportList’ parameter of ‘jsp/audit/reports/ExportReport.jsp’.
4. Solution / Remediation Steps
Currently, a known solution is not publicly available for this vulnerability. Monitor vendor advisories and apply any released patches or updates as soon as possible. Consider implementing input validation as a temporary mitigation measure if feasible.
4.1 Preparation
- Consider stopping the ADAudit Plus service during patching to ensure consistency, but this may cause downtime. A roll back plan involves restoring from the backup.
- Changes should be approved by a security team or system administrator.
4.2 Implementation
- Step 1: Monitor ManageEngine’s website for official patches and updates related to CVE-2010-2049.
- Step 2: Once available, download and install the patch or update according to the vendor’s instructions.

4.4 Security Practices Relevant to This Vulnerability
Input validation and secure coding practices are crucial for preventing XSS vulnerabilities. Least privilege can limit the impact of a successful exploit.
- Practice 1: Implement robust input validation on all user-supplied data, including URL parameters, form fields, and cookies.
- Practice 2: Enforce least privilege principles to restrict access to sensitive resources and minimize potential damage from compromised accounts.
4.5 Automation (Optional)
5. Verification / Validation
- Post-fix check: Access the ADAudit Plus web interface and confirm the version number has been updated to include the fix.
- Re-test: Attempt to access the vulnerable URL with a test XSS payload (e.g.,
https://[ADAudit Plus server]/jsp/audit/reports/ExportReport.jsp?reportList=) and verify that the script does not execute. - Smoke test: Verify core ADAudit Plus functionality, such as report generation and user authentication, remains operational.
- Monitoring: Monitor web server logs for any suspicious activity related to XSS attempts.
6. Preventive Measures and Monitoring
- Baselines: Update security baselines to include the latest ADAudit Plus version with the applied fix.
- Pipelines: Integrate static application security testing (SAST) tools into the development pipeline to detect XSS vulnerabilities early in the process.
- Asset and patch process: Establish a regular patch review cycle for all critical systems, including ADAudit Plus.
7. Risks, Side Effects, and Roll Back
- Risk or side effect 1: Patch installation may cause temporary downtime.
- Risk or side effect 2: Compatibility issues with other applications or integrations are possible.
- Roll back: Restore the ADAudit Plus configuration from the pre-patch backup and restart the service.
