Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Zoho ManageEngine ServiceDesk Plus MSP before 10611, and 13x before 13004, is vulnerable to authentication bypass when LDAP authentication is enabled.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Zoho ManageEngine ServiceDesk Plus MSP versions before 10611 (MSP versions) and before 13004 (13x versions) contain an authentication bypass vulnerability that allows unauthenticated or authenticated attackers to circumvent authentication controls when LDAP authentication is enabled. The flaw likely involves improper validation of LDAP authentication responses, enabling attackers to gain unauthorized access to the application and potentially administrative functions.

MitigationUpgrade ServiceDesk Plus MSP to version 10611 or later (MSP) or version 13004 or later (13x). If immediate patching is not possible, consider temporarily disabling LDAP authentication and using local accounts, or implementing network-level access controls to limit exposure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm ServiceDesk Plus MSP installation
    Locate the ServiceDesk Plus MSP installation by checking for the service process or checking common installation directories. On Windows, open Services and look for 'ManageEngine ServiceDesk Plus - MSP'. On Linux, check for the servicdesk process or the default installation path.
    Affected if ServiceDesk Plus MSP is installed on the system
  2. Identify installed version
    Access the ServiceDesk Plus MSP web interface login page. Navigate to the About page or the Admin > Server Settings section to view the exact version number displayed.
    Affected if The installed version is 10.6 (MSP) or 13.0 (13x), or any version before 10611 for MSP releases or before 13004 for 13x releases
  3. Verify LDAP authentication is enabled
    Log into the ServiceDesk Plus MSP admin console. Navigate to the LDAP or Active Directory configuration section (typically under Admin > Authentication > LDAP/AD or Settings > LDAP Configuration). Confirm whether LDAP authentication is configured and enabled.
    Affected if LDAP authentication is enabled and the version falls within the affected range
  4. Inspect LDAP configuration settings
    In the LDAP configuration panel, review the authentication settings and connection details. Check if the LDAP directory is properly configured with valid search bases and bind credentials.
    Affected if LDAP authentication is active and the application version is vulnerable to the bypass

Your environment is affected if ServiceDesk Plus MSP is running with LDAP authentication enabled and the installed version is below 10611 (MSP) or below 13004 (13x).

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade ServiceDesk Plus MSP to version 10611 or later (MSP) or version 13004 or later (13x). If immediate patching is not possible, consider temporarily disabling LDAP authentication and using local accounts, or implementing network-level access controls to limit exposure.

Recommended fix High confidence

For 10.x line: upgrade to build 10611 or later. For 13.x line: upgrade to build 13004 or later.

  1. 1. Identify your current ServiceDesk Plus MSP build version in the admin console under 'Admin' > 'System' > 'System Information'
  2. 2. Download the appropriate patch from ManageEngine's official support portal based on your current major version
  3. 3. For versions 10.x: ensure you upgrade to build 10611 or later
  4. 4. For versions 13.x: ensure you upgrade to build 13004 or later
  5. 5. Take a complete backup of the ServiceDesk Plus MSP database and configuration files before upgrading
  6. 6. Schedule the upgrade during a planned maintenance window
  7. 7. Apply the upgrade following ManageEngine's standard upgrade procedure
  8. 8. After upgrade, verify LDAP authentication is functioning correctly
Caveat Review ManageEngine release notes for any configuration or feature changes between your current version and the patched version before upgrading.
