A SQL injection vulnerability exists within the Form Maker component <= v3.6.12 for Joomla. The 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.
- A remote unauthenticated attacker sends a GET request with a crafted SQL injection in one of the vulnerable parameters to the target component page.
- The vulnerable Joomla installation processes the request and executes a SQL query including the injected syntax.
- The webserver/application returns a web page which contains the results of the injected SQL query, exposing sensitive database information.
The attacker must be able to send crafted packets to the target system.
