Description

SEMCMS 3.9 is vulnerable to SQL Injection. Due to the lack of security checks on the input of the application, the attacker uses the existing application to inject malicious SQL commands into the background database engine for execution, and sends some attack codes as commands or query statements to the interpreter. These malicious data can deceive the interpreter, so as to execute unplanned commands or unauthorized access to data.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
