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
IBM Security Secret Server up to 11.0 could allow an attacker to enumerate usernames due to improper input validation. IBM X-Force ID: 199243.

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

IBM Security Secret Server up to version 11.0 contains a username enumeration vulnerability caused by improper input validation. Attackers can determine valid usernames by observing differences in authentication error messages or response patterns, potentially facilitating brute-force attacks.

MitigationUpgrade IBM Security Secret Server to a version beyond 11.0 that includes the fix; alternatively, implement generic error messages that do not reveal whether a username exists and add rate limiting on authentication endpoints.

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 the installed version of IBM Security Secret Server
    Access the Secret Server administration interface, typically at /SecretServer/Admin/About, or check the installed files for version information. The exact path varies by deployment but is usually accessible through the Help or About menu in the admin console.
    Affected if The installed version is any release prior to 11.0, as versions below 11.0 contain the vulnerability.
  2. Verify whether authentication error messages differentiate between invalid usernames and incorrect passwords
    Attempt to log in with a known-invalid username and observe the error message returned. Then attempt to log in with a valid username but an incorrect password. Compare the content and wording of the error messages for both scenarios.
    Affected if The error messages differ in a way that reveals whether the username exists in the system, such as one message stating 'Invalid username' versus another stating 'Invalid password'.
  3. Inspect HTTP response patterns for authentication failures
    Send login requests with invalid usernames and valid usernames (wrong password) and examine the HTTP responses. Look for differences in status codes, response body content, or response headers that could indicate whether the username is valid.
    Affected if The responses differ between invalid username and wrong password scenarios in a way that allows an attacker to enumerate valid usernames.
  4. Review authentication configuration for generic error messaging
    Examine the Secret Server configuration or web.config settings related to authentication error handling. Check whether custom error pages or messages have been configured to present uniform messages regardless of whether the username or password was incorrect.
    Affected if No generic or uniform error messaging is configured, and the system returns distinct error responses based on username validity.

A user is affected if their IBM Security Secret Server installation is version 10.x or earlier and the authentication process returns different error messages or response patterns for invalid usernames versus incorrect passwords, allowing username enumeration.

dbcve · scoped
Upgrade available Upgrade to 11.0 or later
Fixed in 11.0
Interim mitigation

Upgrade IBM Security Secret Server to a version beyond 11.0 that includes the fix; alternatively, implement generic error messages that do not reveal whether a username exists and add rate limiting on authentication endpoints.

Recommended fix Moderate confidence

IBM Security Secret Server 11.0 or later

  1. 1. Review the current IBM Security Secret Server version in use (ensure it is below version 11.0)
  2. 2. Plan for upgrade during a maintenance window
  3. 3. Back up the current Secret Server configuration and database
  4. 4. Upgrade IBM Security Secret Server to version 11.0 or later
  5. 5. Verify the upgrade was successful by logging in and checking the version number
  6. 6. Test username enumeration is no longer possible via the input validation vectors
Caveat Review IBM release notes for version 11.0 for any configuration or feature changes that may affect your deployment
