SQL Injection (SQLi) is a widespread vulnerability type found in web applications, where malicious users can inject arbitrary SQL code into input fields intended for legitimate queries. This vulnerability occurs when user input is not properly sanitized and is directly integrated into SQL queries executed by the web application's database. Exploiting SQL Injection vulnerabilities allows attackers to read or modify sensitive data, execute administrative operations, and even perform operations on the underlying operating system. Applications affected by SQL Injection need proper input validation and parameterization to ensure security and data integrity. The primary risk arises from the application's trust in data provided by users, often resulting in unauthorized data access and manipulation. Vigilant security practices are required to mitigate the impact of SQL Injection in web applications.

The SQL Injection vulnerability in CmsEasy affects the 'aid' parameter, allowing malicious users to execute arbitrary SQL commands within the database. The vulnerability is found in the 'archive' and 'orders' sections of the application, where the 'aid' parameter is improperly validated. Attackers can use this point to input crafted SQL queries, such as UNION SELECT statements, to extract database information or manipulate data. This document details the construction of an SQL injection payload that includes a UNION SELECT command to demonstrate the vulnerability. Due to this flaw, it is possible to execute SQL commands that may bypass security measures and access or modify sensitive data. Administrators must ensure that user input is sanitized and query execution is securely handled to prevent exploitation.

When the SQL Injection vulnerability in CmsEasy is exploited, attackers can perform unauthorized operations on the database server, leading to severe consequences. They may access sensitive user data, such as usernames, passwords, and personal information, which could result in data theft. Attackers might also modify or delete database records, disrupting normal application functionality and leading to data loss. Additionally, the vulnerability could facilitate the introduction of backdoors or malicious scripts, allowing sustained access or total compromise of the server. In some cases, exploitation can extend beyond the database, enabling the execution of operating system commands or the installation of malicious software, posing a long-term security risk. Protecting against SQL Injection is vital to maintain the integrity, confidentiality, and availability of web applications.
