MallBuilder Reserve Username SQL Injection Scanner

Mallbuilder is a multi-user online mall solution based on PHP and MySQL. It allows users to rapidly create powerful online marketplaces akin to platforms such as JD.com, Tmall, or Yihaodian. The software supports enterprise-level, industry-specific, localized, and vertical e-commerce platforms. It is utilized by companies aiming to establish robust online retail operations. Mallbuilder is particularly popular among businesses seeking scalable and customizable e-commerce solutions. The system offers features like product management, customer handling, and transaction processing, making it suitable for diverse market needs.

SQL Injection (SQLi) is a critical vulnerability that can compromise the security of web applications by allowing unauthorized access to the database. This vulnerability occurs when user input is improperly sanitized and used in SQL queries, leading to potential data leakage or manipulation. In the context of Mallbuilder, SQL Injection can be exploited through the 'delid' parameter in the /admin/reserve_username module. Attackers can craft SQL statements to manipulate database operations, posing significant risks to data integrity and confidentiality. Depending on the injected queries, they might obtain sensitive information, alter data, or disrupt services.

Technically, the 'delid' parameter in the /admin/reserve_username module is mishandled, making it susceptible to SQL Injection attacks. The vulnerable endpoint allows attackers to manipulate the SQL query executed on the database. For example, by injecting SQL code into the 'delid' parameter, attackers can modify how the database processes requests. This exploitation could involve extracting valuable data or altering database records. The matcher in use verifies this vulnerability by identifying an SQL injection attempt that results in a predictable output, evidencing the flaw.

When exploited, this SQL Injection vulnerability can have severe consequences. An attacker might gain unauthorized access to sensitive data such as user credentials or financial information stored in the database. More significantly, they could alter or delete records, disrupting normal business operations. The compromised integrity of the database could lead to data corruption or loss, affecting customer trust and causing reputational damage. Besides, attackers can leverage the vulnerability to further penetrate the network, deploying additional attacks affecting the entire ecosystem.
