The SQL Injection vulnerability pertains to unsanitized input being passed into SQL statements through the 'chk' parameter in the admin/service_fee module. This flaw allows attackers to manipulate the SQL query by injecting arbitrary SQL code. If exploited, the vulnerability might allow attackers to view, modify, add, or delete information within the database. This type of injection can compromise data integrity and access control in the database, potentially leading to data breaches. Proper input validation and parameterized queries are essential in mitigating SQL Injection vulnerabilities. This scanner focuses on identifying the vulnerable SQL execution points within the application. Detection of such vulnerabilities is crucial for maintaining data security and application integrity.

In technical terms, the vulnerability arises from insufficient validation of the 'chk' parameter within SQL queries. This parameter is susceptible to SQL code injection, allowing attackers to execute arbitrary commands within the database. The crafted SQL statements can manipulate or disrupt the application’s data layer, often leading to unauthorized data access. The scanner tests by injecting crafted payloads that aim to alter the intended SQL commands. By analyzing the application's response, it's possible to ascertain if the input is appropriately sanitized or if it’s vulnerable to exploitation. Detecting such vulnerabilities typically involves examining the database interaction points extensively.

If this SQL Injection vulnerability is exploited, malicious actors can gain unauthorized access or modify sensitive data. They might manipulate the application's logic to grant themselves elevated privileges or compromise the confidentiality of data handled by the system. Additionally, exploitation can result in service outages or data loss due to the manipulation or destruction of database information. Furthermore, attackers might also use the injection as a pivot to launch further attacks internally, potentially compromising related systems or accessing further sensitive domains. Ultimately, exploitation jeopardizes the system's security, risking data breaches and financial losses to the businesses involved.
