Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-643: Improper Neutralization of Data within XPath Expressions ('XPath Injection'), where the product uses external input to dynamically construct an xpath expression used to retrieve data from an xml database, but it does not neutralize or incorrectly neutralizes that input. this allows an attacker to control the structure of the query. In Concrete5/concrete5, 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.

Source Advisory Statement

Concrete5 CMS version 9.1.3 contains an XPath injection vulnerability that allows attackers to manipulate URL path parameters with malicious payloads. Attackers can flood the system with crafted requests to potentially extract internal content paths and system information.
