Weaver E-Cology is a comprehensive office automation (OA) platform developed by Weaver Network, widely adopted by enterprises to streamline internal workflows, document management, and communications. It integrates modules for project management, HR, and CRM, enabling centralized data handling and process automation. Corporate IT departments rely on it to enhance operational efficiency and maintain secure information flows across departments.
SQL Injection (SQLi) is a critical vulnerability that arises when user-supplied data is improperly sanitized before being included in database queries. In Weaver E-Cology, this flaw occurs in the getSqlData interface, where insufficient input validation allows attackers to inject malicious SQL commands. This can lead to unauthorized data access or manipulation.
The vulnerability specifically resides in the getSqlData endpoint, which processes user inputs without adequate parameterization. Attackers can craft payloads that bypass filters, enabling arbitrary SQL execution. The flaw is exploitable via HTTP requests to this interface, making it accessible remotely without authentication in some configurations.
If exploited, an attacker can extract sensitive data such as user credentials, financial records, or proprietary business information. They may also modify or delete database contents, leading to data integrity loss or service disruption. This poses severe risks to organizational confidentiality and operational continuity.
- Implement strict input validation and sanitization for all parameters passed to the getSqlData interface.
- Use parameterized queries or prepared statements to separate SQL logic from user input.
- Apply the principle of least privilege to database accounts used by E-Cology, limiting access to only necessary tables.
- Regularly update Weaver E-Cology to the latest version to receive security patches.
- Conduct periodic security audits and penetration tests focusing on SQL injection vectors.
- Deploy a web application firewall (WAF) to filter malicious SQL payloads.
- Disable or restrict access to the getSqlData endpoint if not required for business operations.
- Monitor database logs for unusual query patterns indicative of exploitation attempts.
