SQL Injection is a code injection technique that might destroy a database. It is one of the most common web hacking techniques. SQL Injection is the placement of malicious code in SQL statements, via web page input. It allows attackers to execute arbitrary SQL code on the database, which can be used to obtain sensitive information or compromise the host system. This type of vulnerability occurs when user input is incorrectly sanitized, allowing attackers to alter the SQL queries executed against a database. The impact of this vulnerability can be severe, ranging from data theft or loss to complete control over the internal systems of an application. Understanding and testing for SQL Injection is crucial for database security.

The CmsEasy crossall_act functionality has been identified as having a SQL Injection vulnerability. The vulnerable end point is in the file service.php; specifically, the act parameter within the crossall case. Users can exploit this by encrypting SQL statements and executing any SQL command. When the application fails to properly sanitize input before processing it, attackers can manipulate queries by providing a structured input. The payload may exploit specific parts of the SQL command, and the application response often reveals whether the attack was successful. Attackers might target specific parameters, such as 'sql', to inject malicious statements.

If left unresolved, the SQL Injection vulnerability in CmsEasy can have significant consequences. Exploiting this flaw could allow attackers to retrieve or modify sensitive data such as user credentials. Furthermore, it may lead to unauthorized access to the administrator area and the potential seizure of administrative accounts. Attackers could execute specific commands to corrupt the database, impede the application performance, or even create backdoors for future attacks. This poses risks not only to the accuracy and availability of data but also to user trust and business reputation. In more severe cases, malicious actors may leverage this vulnerability to gain a foothold within the organization's internal network.
