Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Jackalope/jackalope doctrine dbal, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\n\nUsers can provoke SQL injections if they can specify a node name or query.\n\n### Patches\n\nUpgrade to version 1.7.4\n\nIf 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)`.\n\n### Workarounds\n\nNode 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.\n\nIf queries are never done from user input, or if you validate the user input to not contain `;`, you are not affected. \n\n### References\n\nNo further references.\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open an issue in [jackalope/jackalope-doctrine-dbal repo](https://github.com/jackalope/jackalope-doctrine-dbal/issues)\n",
