Weaver E-Cology getsqldata SQL Injection Scanner

Weaver E-Cology is an office automation (OA) system widely used in enterprises for managing internal workflows, document processing, and communications. Developed by Weaver Network, it is designed to improve organizational efficiency through streamlined processes and centralized information management. The software offers various modules for tasks such as project management, human resources, and customer relationship management, making it versatile for different business needs. It is typically used by corporate IT departments to tie together various business processes and information flows. Companies benefit from the system's capability to handle large volumes of data and transactions securely. E-Cology is especially popular in sectors that require stringent documentation and approval processes.

SQL Injection (SQLi) is a critical security vulnerability that allows attackers to interfere with the queries that an application makes to its database. It occurs when malicious actors execute arbitrary SQL code on a database, potentially accessing, modifying, or deleting data. In the context of Weaver E-Cology, the vulnerability is specifically found in the 'getSqlData' interface when the application is using an MSSQL database. This allows unauthorized users to inject SQL commands as part of request parameters, bypassing standard authentication and gaining direct access to the underlying data. SQL Injection attacks pose a significant threat due to the potential impact, ranging from data breaches to complete control over the database.

The SQL Injection vulnerability in Weaver E-Cology is located in the 'getSqlData' API. This endpoint does not properly sanitize the SQL queries when interfacing with an MSSQL database, particularly in forming queries that involve the 'sys.fn_sqlvarbasetostr' function. Attackers can manipulate the 'sql' parameter of the endpoint to inject malicious SQL code. For example, an injected payload might attempt to retrieve sensitive data by altering the SQL query structure. This vulnerability highlights the need for rigorous input validation and the use of parameterized queries to mitigate risks.

Exploitation of the SQL Injection vulnerability in Weaver E-Cology could result in unauthorized access to sensitive data, such as user credentials and company information. It might also allow attackers to alter or delete database records, potentially leading to data loss or service disruption. In a worst-case scenario, full database compromise could be achieved, enabling attackers to execute remote commands on the server. This can undermine system integrity, affect business operations, and lead to significant financial and reputational damage.
