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
The (1) Zend_Ldap class in Zend before 1.12.9 and (2) Zend\Ldap component in Zend 2.x before 2.2.8 and 2.3.x before 2.3.3 allows remote attackers to bypass authentication via a password starting with a null byte, which triggers an unauthenticated bind.

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

The Zend_Ldap class in Zend Framework 1.x before 1.12.9 and 2.x before 2.2.8/2.3.3 contains an authentication bypass vulnerability. By submitting a password starting with a null byte (\x00), attackers can trigger an unauthenticated LDAP bind, bypassing the authentication mechanism entirely.

MitigationUpgrade to Zend Framework 1.12.9 or later, or Zend Framework 2.2.8/2.3.3 or later. Alternatively, implement input validation to reject passwords containing null bytes before passing them to the LDAP bind operation.

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 Zend Framework version
    Locate the Zend library files in your project (typically in library/Zend/ or vendor/zendframework/zendframework/). Check the Version.php file or the changelog to determine the exact installed version number.
    Affected if The installed version is 1.x before 1.12.9, or 2.x before 2.2.8 or 2.3.3 (specifically 2.0.0 through 2.2.5 as listed)
  2. Verify Zend_Ldap class is in use
    Search your codebase for includes or references to Zend_Ldap class (e.g., 'Zend_Ldap', 'Zend\Ldap\Ldap' in ZF2). Look for LDAP authentication logic that instantiates or extends this class.
    Affected if Your application uses the Zend_Ldap class for LDAP bind operations
  3. Check LDAP authentication configuration
    Inspect your application's configuration files and authentication modules to determine if LDAP bind is enabled as an authentication method. Look for LDAP adapter configurations in your auth setup.
    Affected if LDAP authentication is enabled and your application performs LDAP binds using user-provided passwords

You are affected if your installed Zend Framework version is vulnerable (1.x before 1.12.9 or 2.x up to 2.2.5/2.3.3) AND your application uses the Zend_Ldap class for authentication with user-supplied passwords.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 1.12.7
Interim mitigation

Upgrade to Zend Framework 1.12.9 or later, or Zend Framework 2.2.8/2.3.3 or later. Alternatively, implement input validation to reject passwords containing null bytes before passing them to the LDAP bind operation.
