Joomla Gallery WD SQL Injection Scanner

Joomla Gallery WD is a component used in Joomla!, an open-source Content Management System (CMS), for creating image galleries. Developed to offer users a comprehensive tool for image display, it allows web developers to devise visually appealing galleries seamlessly integrated into Joomla-based websites. Joomla is widely implemented by small to large organizations globally for managing website content, making components like Gallery WD pivotal in enhancing site aesthetics. Users often choose such components for their ability to effectively showcase multimedia content, providing versatility through customizable interfaces. With over a million downloads, Joomla's components are a staple in CMS infrastructure, appreciated for their simplicity and robust functionality.

SQL Injection (SQLi) is a code injection technique that web attackers use to exploit web application vulnerabilities and access or manipulate the database. This type of flaw allows external users to interact with the database through the application's web interface by injecting SQL commands into input fields. The vulnerability resides in inadequate input validation, enabling an attacker to interfere with the application’s interaction with the database. Exploiting SQL Injection can lead to unauthorized data exposure, modification of database content, or even admin-level control over the affected system. Such vulnerabilities are commonly prioritized due to their capacity to compromise confidentiality, integrity, and availability of data.

In the Joomla Gallery WD component, the vulnerability exists because of improper validation of input parameters such as 'theme_id' and 'image_id'. Attackers can exploit this flaw by injecting malicious SQL queries into these parameters, potentially leading to unauthorized database access. This specific vulnerability is revealed when a malformed query returns specific responses indicating SQL operations. The vulnerability demonstrates itself through error responses such as status code 500 and MD5 hash collision checks within the returned content. The lack of server-side query sanitation facilitates the success of these SQL injection attacks.

If exploited, the SQL Injection vulnerability can result in severe consequences, including unauthorized access to sensitive database information, data corruption, or theft, and escalation of privileges within the system. An attacker could manipulate database records, cause denials of service by overwhelming the database with excessive queries, or even execute administrative database commands. Exploiting such vulnerabilities could lead to damaging data leaks, potentially leveraging further attacks by abusing the obtained data. The integrity and confidentiality of the affected system's data are put at risk, imposing significant threats to businesses that rely on the integrity and security of their information systems.
