SQL Injection is a critical vulnerability that attackers exploit to interfere with an application's queries to a database. This dangerous flaw allows unauthorized users to access, modify or delete data, potentially gaining unauthorized access to data-sensitive systems. By injecting malicious SQL code, attackers can manipulate database queries and execute arbitrary commands. This vulnerability arises from inadequate input validation, allowing crafted input to be processed unsafely within database queries. Despite relational databases offering mechanisms to avoid these types of attacks, improper parameterized queries and input sanitation practices can lead to SQL Injection vulnerabilities. It poses severe risks including data compromise, unauthorized data access, and potential system control.

The specific SQL Injection vulnerability in openSIS Classic v9.1 is located in the resetuserinfo.php file, due to insufficient validation of the $username_stn_id parameter. This flaw allows malicious actors to inject SQL commands via the manipulated parameter. An example exploitation scenario involves the injection of a time-based SQL payload, which can result in controlled execution delay, used to infer boolean results from database operations. The vulnerability is critical because it jeopardizes the confidentiality, integrity, and availability of the database by allowing attackers to execute arbitrary SQL commands. Successful exploitation can allow attackers to access confidential data, manipulate existing records, or inject persistent malicious scripts that can affect users accessing the system.

If this SQL Injection vulnerability is exploited by malicious individuals, it could lead to unauthorized access to sensitive information, database corruption, and potential system downtime. Attackers could execute malicious commands leading to data breaches, with severe consequences like exposure of personally identifiable information (PII) or intellectual property. Exploitation could result in significant financial loss, erosion of user trust, and legal repercussions due to data privacy violations. The compromise of database integrity might lead to incorrect or altered data rendering the application unreliable. Additionally, attackers could exploit the gained access to infiltrate deeper into connected network systems, posing further security risks.
