CMS Joomla com_gmap getData getDatamarker Display SQL Injection

A SQL injection vulnerability exists within the Google Map Landkarten component <= v4.2.3 for Joomla. This vulnerability exists as a result of unfiltered user-controlled input being used to construct and execute a SQL query. An unauthenticated remote attacker can leverage the vulnerability to exfiltrate sensitive information from the database to enable further attacks or potentially steal data.

Exploitation

Stages

1. The remote unauthenticated attacker sends a GET or POST request with a crafted SQL injection in one of the vulnerable parameters to the target component page.
2. The vulnerable Joomla installation processes the request and executes a SQL query including the injected syntax.
3. The web server/application returns a web page which contains the results of the injected SQL query, exposing sensitive database information to theft.

Prerequisites

The attacker must be able to send crafted packets to the target system.
