DedeCMS SQL Injection Vulnerability Scanner

DedeCMS is a content management system widely adopted for website creation and management, favored for its user-friendly interface and flexible content management capabilities. It serves a broad user base, including individual bloggers, small and medium enterprises, and large organizations, for publishing, editing, and organizing web content. DedeCMS facilitates the development of dynamic websites with its extensive feature set and plugin ecosystem, making it a popular choice among web developers and content creators. However, being a widely used platform also makes it a target for various cyber-attacks, including SQL Injection, which can compromise data security and integrity.

The SQL Injection vulnerability in DedeCMS allows unauthenticated remote attackers to execute arbitrary SQL commands through the ajax_membergroup.php endpoint via the membergroup parameter. This critical security flaw permits attackers to manipulate database queries, potentially leading to unauthorized data access, manipulation, or deletion. SQL Injection vulnerabilities are severe because they can compromise the entire database and, in some cases, the underlying server, posing significant risks to confidentiality, integrity, and availability of the data.

The vulnerability specifically exists within the 'ajax_membergroup.php' file, where the 'membergroup' parameter is not properly sanitized before being used in a SQL query. This lack of proper input validation enables attackers to inject malicious SQL code into the backend database. By crafting a malicious URL that includes the SQL Injection payload, an attacker can manipulate database queries to leak sensitive information, escalate privileges, or even execute arbitrary commands on the server hosting the DedeCMS application.

Exploiting this vulnerability could lead to severe consequences, including but not limited to, theft of sensitive data such as user credentials, personal information, and proprietary content. Attackers could also leverage this vulnerability to compromise the website's integrity by altering or deleting content. In the worst-case scenario, this could extend to gaining unauthorized access to the underlying server, leading to a complete system takeover and further attacks on associated networks.
