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
In ManageEngine ADSelfService Plus, RecoveryManager Plus, M365 Manager Plus, and ADAudit Plus, the SSO tickets generated to authenticate that session could be predicted by an unauthenticated user, leading to account takeover.

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 · moderate confidence

This vulnerability in ManageEngine ADSelfService Plus, RecoveryManager Plus, M365 Manager Plus, and ADAudit Plus allows unauthenticated attackers to predict SSO tickets used for session authentication due to insufficient randomness in ticket generation. Attackers can forge valid session tokens and achieve account takeover without any credentials.

MitigationUpgrade to vendor-provided patches addressing this issue. If no patch is immediately available, consider restricting access to the affected endpoints via network controls while the vendor fix is being applied.

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 ManageEngine products
    Review installed software or running services on the system for any of the following: ADSelfService Plus, RecoveryManager Plus, M365 Manager Plus, ADAudit Plus. Check Windows Services, Linux service listings, or application directories.
    Affected if Any of these four ManageEngine products are present on the system
  2. Determine the installed product version
    Locate the version information in the product's admin console, about page, or check the installation directory for a version file. Common locations include the product's bin folder or a version.txt file within the installation root.
    Affected if The installed version matches or precedes the versions listed in the vendor security advisory (compare against official CVE documentation)
  3. Confirm SSO authentication is enabled
    Log into the product admin console and navigate to the authentication or security settings. Check whether Single Sign-On (SSO) or session-based authentication using SSO tickets is configured and active.
    Affected if SSO authentication is enabled and in use for user sessions
  4. Review authentication logs for anomalous patterns
    Examine the product's audit or security logs for any suspicious authentication activity, particularly multiple failed login attempts followed by successful token-based sessions, or unusual ticket reuse patterns.
    Affected if Logs show unexpected session tokens or authentication anomalies that suggest ticket prediction may have occurred

A user is affected if they run any of the four ManageEngine products with SSO enabled and their version matches the vulnerable range per official vendor documentation.
