Discuz! is a widely-used forum software system designed for creating and managing online communities. It is employed by web developers and administrators who need robust features for community engagement and interaction. Known for its versatility, Discuz! offers users a comprehensive platform to run multiple forums under a single installation. It is commonly used by institutions, businesses, and individuals for hosting discussions and content sharing. The software provides a customizable interface and extensive plugins to enhance its functionality. By serving as a central hub for community dialogue, it supports a multitude of online environments.
The SQL Injection vulnerability occurs in Discuz!'s batch.common.php file, potentially allowing attackers to execute arbitrary SQL commands. This form of injection can exploit weaknesses in query handling to manipulate or retrieve data. If left unchecked, the vulnerability poses a significant risk of unauthorized data access or damage. It is commonly targeted by attackers looking to compromise user information or disrupt services. The vulnerability prevention involves ensuring only validated user inputs are processed. Highlighting the importance of database security measures, it serves as a notable threat in web applications.
The vulnerability is specifically located in the batch.common.php end point of Discuz! Exploitation occurs when malicious SQL queries are injected through the `action=modelquote` parameter. Attackers can employ this vector to execute commands that manipulate the database. For example, by using SQL payloads, they can view, alter, or delete data within Discuz! databases. Unsanitized inputs in this section are the root cause of exposure. Techniques like parameterized queries should be applied to mitigate misuse. Successfully identifying this vulnerability can prevent significant data compromise.
When exploited, the SQL Injection vulnerability can lead to severe consequences such as unauthorized access to sensitive data, database manipulation, and complete service disruption. Attackers may extract user credentials, tamper with records, or deface components of the forum. In the worst-case scenario, it enables full administrative control to external malicious actors. Furthermore, exploiting SQL vulnerabilities can create backend instability, potentially resulting in data loss or corruption. It can also lead to reputational damage for websites running on vulnerable Discuz! installations.
