Joomla Component Joomloc-Lite SQL Injection Scanner

The Joomla! Component Joomloc-Lite is a plugin for the Joomla! Content Management System (CMS) used to manage and host content on the internet. Primarily, it aids webmasters and developers in managing location-based services within their site architecture. Given its integration into Joomla!, it is actively used by small to medium-sized businesses and web development professionals seeking location-based features for their websites. This component simplifies tasks like handling location-specific data, making it a popular choice for service providers and directory-based websites. With its intuitive interface, users can offer enhanced content organization and location management capabilities. Utilized globally, it caters to those focusing on diverse geographical content.

The vulnerability identified in the Joomla! Component Joomloc-Lite is a SQL Injection (SQLi). This type of vulnerability enables attackers to execute arbitrary SQL commands in the database powering the Joomla! site. The attack exploits a faulty implementation allowing manipulation of a parameter, in this case, 'site_id', which directly interacts with SQL queries. Such vulnerability is often targeted by attackers aiming to compromise database security. This specific vulnerability can severely impact data integrity and confidentiality within the web service. It requires immediate remediation to prevent exploitation by malicious actors.

The technical details of this vulnerability involve exploiting the 'site_id' parameter in a HTTP GET request. The vulnerability is located at the endpoint '/index.php', primarily affecting the 'option=com_joomloc' feature. Attackers manipulate the 'site_id' parameter using UNION ALL SELECT statements, substituting user input to retrieve unauthorized data. An illustrative example is supplying the parameter "-5527' UNION ALL SELECT md5(1)-- IjSf", enabling retrieval and authentication bypass. The inclusion of crafted SQL input facilitates querying the database beyond intended access rights. Attention to parameter sanitization and prepared statements can mitigate this risk.

When exploited, this SQL Injection vulnerability in the Joomla! Component Joomloc-Lite can lead to unauthorized access to sensitive data stored in the database. A compromised system may suffer data breaches, with attackers potentially exfiltrating or modifying critical information. Confidential user data such as login credentials, personal details, and other sensitive records may be exposed. The exploit could lead to the defacement or disruption of web services, impacting the integrity and availability of hosted content. In severe scenarios, control over the web server could be lost, allowing further attacks and unauthorized resource usage.
