Joomla! Component OS Property SQL Injection Scanner

Joomla! is a widely used open-source Content Management System (CMS) offering a flexible and extensible platform for creating websites and online applications. It's favored by individuals and businesses for its ease of use and vast array of extensions and templates. The OS Property component is primarily used by real estate companies to manage property listings, providing a rich set of features to cater to the needs of real estate management. This particular component adds significant functionality for real estate businesses operating on Joomla! sites, making it essential for managing complex property databases. The component’s architecture is designed to integrate seamlessly with Joomla!'s core capabilities, facilitating extensive customization and management options. Its usage spans small to large organizations focused on real estate operations, offering features that streamline property management and customer interactions.

SQL Injection (SQLi) is a significant security vulnerability that allows attackers to execute arbitrary SQL commands on the database of a vulnerable application. This vulnerability arises when user-controlled inputs are improperly sanitized and directly included in SQL queries, leading to unauthorized manipulation or extraction of sensitive database information. The specific vulnerability in the Joomla! OS Property v3.0.8 component exposes the catIds parameter to injection attacks. Properly crafted inputs can manipulate the query logic, allowing unauthorized access to or alteration of the database. SQL injection is a critical issue because it can compromise the integrity and confidentiality of database contents, potentially leading to severe data breaches. The vulnerability requires attention and remediation to prevent any malicious exploitation by attackers.

Technical details of the SQL Injection vulnerability exist in the catIds parameter, where an attacker can manipulate input to execute SQL commands. The path identified as vulnerable is {{BaseURL}}/index.php?option=com_osproperty&view=ltype&catIds[0], where the SQL logic can be altered. Attackers can exploit the endpoint by injecting SQL payloads that alter the intended execution flow of database queries. In this case, the injection vector is achieved by appending certain parameters to the request URL, which the application improperly sanitizes before execution. The example payload used in the detection checks for execution of MD5 hash calculation through SQL, indicating SQL code execution capability. This vulnerability can lead to data exposure and unauthorized access if left unpatched.

When exploited, SQL Injection can have dire consequences, including unauthorized access to the database, data exfiltration, unauthorized data modification, and potential loss of data integrity. Attackers can potentially gain complete control over the database server by leveraging other vulnerabilities combined with a successful SQL injection attack. The affected system may become a stepping stone for further attacks through privilege escalation or lateral movement within the network. Organizations may suffer reputational damage, financial losses due to ransom attempts, and possible legal implications from data breaches. Ensuring the security of SQL queries is critical to maintaining the database's confidentiality, integrity, and availability.
