What is GHSA-2x36-qhx3-7m5f?
GHSA-2x36-qhx3-7m5f is a SQL injection vulnerability in zendframework/zendframework1, published on 7 Jun 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
For instance, the following code is affected by this issue:
$db = Zend_Db::factory( /* options here */ );
$select = $db->select()
->from(array('p' => 'products'))
->order('MD5(1); drop table products');
echo $select;
This code produce the string:
SELECT "p".* FROM "products" AS "p" ORDER BY MD5(1);drop table products ASC
instead of the correct one:
SELECT "p".* FROM "products" AS "p" ORDER BY "MD5(1);drop table products" ASC
The SQL injection occurs because we create a new Zend_Db_Expr() object, in presence of parentheses, passing directly the value without any filter on the string.
Which versions are affected by GHSA-2x36-qhx3-7m5f?
2 open source packages ship an affected version, including zendframework/zendframework1.
| Package | Affected | Fixed in |
|---|---|---|
zendframework/zendframework1 Packagist | From 1.12.0 | 1.12.7 |
zendframework/zendframework1 Packagist | From 1.12.0 | 1.12.7 |
How do I fix GHSA-2x36-qhx3-7m5f?
Upgrade zendframework/zendframework1 to 1.12.7 or later.
Use parameterised queries everywhere and never build SQL by joining strings. Upgrade affected software first; a web application firewall only buys time. More about SQL injection.
