1. Introduction
ManageEngine ServiceDesk Plus Default Administrator Credentials allows unauthenticated access to a web application due to the use of default administrative credentials. This means an attacker could gain full control over the system without needing valid user accounts, potentially leading to data breaches, service disruption, and unauthorized modifications. Systems running ManageEngine ServiceDesk Plus with unchanged default credentials are affected.
2. Technical Explanation
The remote ManageEngine ServiceDesk Plus install uses a default set of credentials (‘administrator’ / ‘administrator’) to control access to its management interface. An attacker can exploit this by simply attempting to log in using these well-known credentials. This is due to a lack of enforced password changes on initial setup.
- Root cause: Use of hardcoded default administrator credentials without requiring an immediate change during installation.
- Exploit mechanism: An attacker attempts to login with the ‘administrator’ username and ‘administrator’ password via the web interface. Successful authentication grants full administrative access.
- Scope: ManageEngine ServiceDesk Plus installations using default credentials.
3. Detection and Assessment
- Quick checks: Access the login page of your ManageEngine ServiceDesk Plus instance. If no password has been changed, you will be able to log in using ‘administrator’ / ‘administrator’.
- Scanning: Nessus plugin ID 108795 can detect this vulnerability. This is an example only and may require updating.
- Logs and evidence: Check application logs for successful login attempts from the default administrator account.

Provide precise, ordered steps to fix the issue.
4.1 Preparation
- No services need to be stopped for this remediation. A roll back plan is to restore from backup if issues occur.
4.2 Implementation
- Step 1: Log into the application using existing credentials (if possible).
- Step 2: Click ‘Admin’ in the top right corner of the screen.
- Step 3: Select ‘Personalize’.
- Step 4: Select ‘Change Password’.
- Step 5: Enter a strong, unique password and confirm it.
- Step 6: Click ‘Save’.
4.3 Config or Code Example
Before
# No config example - default credentials are set via the web interface.After
# Password changed from 'administrator' to a strong, unique password via the web interface.4.4 Security Practices Relevant to This Vulnerability
List only practices that directly address this vulnerability type.
- Practice 1: Safe defaults – avoid shipping products with default credentials or enforce immediate password changes on first login.
- Practice 2: Least privilege – limit the permissions of administrator accounts to only what is necessary.
4.5 Automation (Optional)
No automation script available for this vulnerability.
5. Verification / Validation
Explain how to confirm the fix worked.
- Post-fix check: Attempt to log in with ‘administrator’ / ‘administrator’. The login should now fail.
- Re-test: Repeat the quick checks from section 3, which should no longer succeed using default credentials.
- Smoke test: Verify that you can still log in with your new administrator password and access key features of ServiceDesk Plus.
