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.

The previous zendframework upload incorrectly fixes CVE-2015-3154, causing a regression. This update corrects this problem. Thanks to &#x415;&#x432;&#x433;&#x435;&#x43D;&#x438;&#x439;

Updated php-ZendFramework packages fix multiple vulnerabilities :

XML eXternal Entity (XXE) and XML Entity Expansion (XEE) flaws were discovered in the Zend Framework. An attacker could use these flaws to cause a denial of service, access files accessible to the server process, or possibly perform other more advanced XML External Entity (XXE) attacks (CVE-2014-2681, CVE-2014-2682, CVE-2014-2683).

Using the Consumer component of Zend_OpenId, it is possible to login using an arbitrary OpenID account (without knowing any secret information) by using a malicious OpenID Provider. That means OpenID it is possible to login using arbitrary OpenID Identity (MyOpenID, Google, etc), which are not under the control of our own OpenID Provider. Thus, we are able to impersonate any OpenID Identity against the framework (CVE-2014-2684, CVE-2014-2685).

The implementation of the ORDER BY SQL statement in Zend_Db_Select of Zend Framework 1 contains a potential SQL injection when the query string passed contains parentheses (CVE-2014-4914).

Due to a bug in PHP's LDAP extension, when ZendFramework's Zend_ldap class is used for logins, an attacker can login as any user by using a null byte to bypass the empty password check and perform an unauthenticated LDAP bind (CVE-2014-8088).

The sqlsrv PHP extension, which provides the ability to connect to Microsoft SQL Server from PHP, does not provide a built-in quoting mechanism for manually quoting values to pass via SQL queries;
developers are encouraged to use prepared statements. Zend Framework provides quoting mechanisms via Zend_Db_Adapter_Sqlsrv which uses the recommended double single quote ('') as quoting delimiters. SQL Server treats null bytes in a query as a string terminator, allowing an attacker to add arbitrary SQL following a null byte, and thus create a SQL injection (CVE-2014-8089).

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. (CVE-2014-8088)

The 1.12.9, 2.2.8, and 2.3.3 releases of the Zend Framework fix a SQL injection issue when using the sqlsrv PHP extension. Full details are available in the upstream advisory. (CVE-2014-8089)

A vulnerability has been found and corrected in php-ZendFramework :

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 (CVE-2014-8088).

The updated packages have been upgraded to the latest ZendFramework (1.12.9) version which is not vulnerable to this issue.

# Security Fixes

  - **ZF2014-05**: Due to an issue that existed in PHP's     LDAP extension, it is possible to perform an     unauthenticated simple bind against a LDAP server by     using a null byte for the password, regardless of     whether or not the user normally requires a password. We     have provided a patch in order to protect users of     unpatched PHP versions (PHP 5.5 <= 5.5.11, PHP 5.4 <=     5.4.27, all versions of PHP 5.3 and below). If you use     Zend\Ldap and are on an affected version of PHP, we     recommend upgrading immediately.

    - **ZF2014-06**: A potential SQL injection vector       existed when using a SQL Server adapter to manually       quote values due to the fact that it was not escaping       null bytes. Code was added to ensure null bytes are       escaped, and thus mitigate the SQLi vector. We do not       recommend manually quoting values, but if you do, and       use the SQL Server adapter without PDO, we recommend       upgrading immediately.

  - 'ZF2014-06: SQL injection vector when manually quoting     values for sqlsrv extension, using null byte'     (http://framework.zend.com/security/advisory/ZF2014-06)

Security release

  - ZF2014-05, which mititages null byte poisoning of the     password provided for LDAP authentication, thus     prevening unauthorized LDAP binding. This corrects for     unpatched versions of PHP (versions 5.5.11 and below,     5.4.27 and below, and any prior releases).

    - ZF2014-06, which mitigates null byte poisoning of       quoted SQL values provided to the sqlsrv extension,       thus preventing a potential SQL injection vector.
