CVE-2014-8089: Zend Framework SQL Injection Vulnerability

Background

The Zend Framework is a popular open-source PHP framework that provides a collection of professional PHP packages for developing web applications. It offers a wide range of features and components for building robust and secure applications. However, versions before 1.12.9, 2.2.x before 2.2.8, and 2.3.x before 2.3.3 are vulnerable to a SQL injection attack when using the sqlsrv PHP extension.

Vulnerability Detail

This vulnerability allows remote attackers to execute arbitrary SQL commands by exploiting a null byte injection. By manipulating the input data, an attacker can inject malicious SQL queries, potentially leading to unauthorized access, data leakage, or data manipulation. The vulnerability affects applications using the affected versions of the Zend Framework with the sqlsrv PHP extension.

composer require zendframework/zendframework1:1.12.9

Workaround

If upgrading to the patched versions is not immediately feasible, a temporary workaround is to disable the sqlsrv PHP extension or implement proper input validation and sanitization to prevent SQL injection attacks. Here is an example of input validation using prepared statements in PHP:

$pdo = new PDO('sqlsrv:Server=localhost;Database=myDB', 'username', 'password');
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username);
$stmt->execute();
$result = $stmt->fetchAll();

Conclusion

The Zend Framework is vulnerable to a SQL injection attack when using the sqlsrv PHP extension in versions before 1.12.9, 2.2.x before 2.2.8, and 2.3.x before 2.3.3. It is crucial to upgrade to the latest patched versions or apply the recommended workarounds to mitigate the risk of exploitation.
