CVE-2021-43822: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
(updated )
Jackalope Doctrine-DBAL is an implementation of the PHP Content Repository API (PHPCR) using a relational database to persist data. In affected versions users can provoke SQL injections if they can specify a node name or query. Upgrade to resolve this issue. If that is not possible, you can escape all places where $property
is used to filter sv:name
in the class Jackalope\Transport\DoctrineDBAL\Query\QOMWalker
: XPath::escape($property)
. Node names and xpaths can contain "
or ;
according to the JCR specification. The jackalope component that translates the query object model into doctrine dbal queries does not properly escape the names and paths, so that a accordingly crafted node name can lead to an SQL injection. If queries are never done from user input, or if you validate the user input to not contain ;
, you are not affected.
