Yonyou KSOA SQL Injection Vulnerability in work_update.jsp

A SQL injection vulnerability exists in Yonyou KSOA version 9.0, specifically within the '/worksheet/work_update.jsp' file. The issue arises because the application does not properly sanitize the 'Report' parameter, allowing attackers to inject malicious SQL code. This vulnerability can be exploited remotely without authentication, leading to unauthorized database access, data manipulation, and potential disruption of services.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized access to database information, alteration of data, and in some cases, execution of administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a GET request to 'work_update.jsp' with a crafted 'Report' parameter that includes SQL injection payloads. The injection takes advantage of the application's failure to validate or sanitize user input before it is processed in SQL queries.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
