The platform supports multi-language content management, making it appealing for global enterprises.

SQL Injection is a critical vulnerability often found in applications that inadequately sanitize user inputs, allowing attackers to execute arbitrary SQL commands. This vulnerability can lead to unauthorized access to sensitive data, data modification, and even denial of service, affecting application integrity and confidentiality. Attackers exploit this by manipulating input fields to insert SQL code into queries executed by the database. SQL Injection remains one of the most prevalent security vulnerabilities due to improper handling of input validation and weak control over database interactions. It can affect numerous applications, from web applications to enterprise management systems, impacting data security. Ensuring robust input validation and database interaction control are pivotal in mitigating this risk.

The Dotnet CMS is vulnerable at the endpoint '/user/City_ajax.aspx?CityId'. The parameter 'CityId' accepts user input, which can be manipulated using SQL syntax to extract or tamper with database information. An attacker can insert a union SQL statement and leverage the hash function to reveal sensitive hash values. If the SQL syntax is executed correctly, it returns a successful HTTP 200 status code. The vulnerability arises due to a lack of proper sanitization and bounds checking within input fields, allowing the injection and disparate execution of SQL commands. This exploitation scenario further exposes database schemas, table structures, and potentially sensitive data logging mechanisms to unauthorized users. The primary risk is unauthorized administrative control over the database, making it an attractive target for cyber-attackers.

When exploited, the SQL Injection vulnerability in Dotnet CMS can have devastating impacts, including full database compromise. Attackers can extract, modify, or delete sensitive data, undermine user privacy, and exploit administrative privileges to take control of server resources. Business continuity can be severely impacted, leading to financial losses if critical data is altered or deleted. The exploitation could extend to executing remote commands, potentially leading to broader system compromises beyond the initial database context. Moreover, stolen sensitive data might be sold or used for further targeted attacks, increasing reputational damage for affected entities. The vulnerability can also be employed to perform denial of service attacks, rendering the application unavailable to legitimate users.
