SQL Injection is a code injection technique that might destroy your database. It is one of the most common web hacking techniques. It exploits a web application which uses input from a user as part of a SQL query to an underlying database. It typically allows an attacker to view data that they are not normally able to retrieve, including data belonging to other users, or any other data that the application itself is able to access. SQL Injection flaws can allow for the complete compromise of the host running the application, bypass authentication and access control, exfiltrate data, or corrupt the application’s data.
The vulnerability in question specifically arises from improper validation of user inputs within the script 'report_bi.func.php' in Tongda OA v6. Attackers can manipulate input fields to execute arbitrary SQL commands through entries such as the 'dataset_id' parameter. By exploiting this issue, attackers can extract sensitive information from the database, such as user credentials. The endpoint facilitates union-based injections, which may allow attackers to retrieve current database and user details from the application. The lack of proper parameterization of queries makes this endpoint an active target for SQL Injection attacks.
Exploiting this SQL Injection vulnerability could allow an attacker unauthorized access to sensitive data stored in Tongda OA. Attackers might gain access to confidential information, alter existing data, perform administrative operations, or even impersonate users. Such breaches could lead not only to serious data privacy violations but also financial and reputational damages if sensitive company data is exposed or manipulated. Continuous database exploitation without mitigation could result in a fully compromised backend and loss of data integrity.
REFERENCES
To mitigate the SQL Injection vulnerability identified in Tongda OA:
- Implement parameterized queries to prevent SQL injection.
- Apply web application firewall (WAF) rules to filter and monitor SQL injection attack patterns.
- Conduct regular security audits and code reviews to detect and rectify potential vulnerabilities.
- Ensure that your application handles error messages securely to avoid information leaks.
- Regularly update the software to include the latest security patches provided by the vendor.
