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 ADSelfService Plus versions below 6401 are vulnerable to the DOS attack due to the malicious LDAP input.

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 ADSelfService Plus versions before 6401 are vulnerable to denial of service when processing specially crafted LDAP input. The application fails to properly validate or sanitize LDAP queries, allowing an attacker to cause the service to become unresponsive or crash.

MitigationUpgrade ADSelfService Plus to version 6401 or later to remediate this vulnerability. If immediate patching is not possible, consider restricting LDAP access through network segmentation or firewall rules.

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. Identify installed ADSelfService Plus version
    Access the product's About or System Information page in the admin console, or check the version file in the installation directory (typically found in the product's main folder or in a 'build' or 'version' file).
    Affected if The installed version is 6.4 or any version lower than 6.4 (for example, 6.3, 6.2, 6.1, etc.). Note that version 6.4 itself is also affected; only version 6401 and later are not vulnerable.
  2. Verify LDAP-based authentication or self-service is configured
    In the ADSelfService Plus admin console, navigate to the LDAP or Directory Service configuration section. Check whether LDAP-based authentication, password reset, or self-service features are enabled and connected to an Active Directory or LDAP directory.
    Affected if LDAP integration is actively configured and in use. The vulnerability is triggered when processing LDAP queries, so LDAP must be enabled for the flaw to be exploitable.
  3. Confirm the build number if running version 6.4
    If the product shows version 6.4, look for a build number or patch level in the About section, installation directory, or release notes. The vulnerable build is 6.4 (any build before build 6401).
    Affected if Running version 6.4 with build number lower than 6401. Versions below 6.4 (such as 6.3.x) are also affected regardless of build number.

You are affected if ADSelfService Plus is running any version below 6.4, or is running version 6.4 with build number below 6401, AND has LDAP-based authentication or self-service features enabled.

Fixed in 6.4
Interim mitigation

Upgrade ADSelfService Plus to version 6401 or later to remediate this vulnerability. If immediate patching is not possible, consider restricting LDAP access through network segmentation or firewall rules.
