CMS Joomla com_saxumastro getItem_getItemQuery SQL Injection

Two SQL injection vulnerabilities exist within versions <= 4.0.14 of the Saxum Astro Joomla component as a result of insufficient sanitization of user-controlled input values. The vulnerabilities allow an unauthenticated remote attack to inject SQL syntax via the ‘publicid’ and ‘signid’ parameters. Successful exploitation of the vulnerabilities results in potentially sensitive data being exfiltrated from the target, enabling further attacks or resulting in theft of data.

Exploitation

Stages

1. A 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 webserver/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.
