Yonyou KSOA SQL Injection Vulnerability in Save Folder JSP File

A SQL injection vulnerability has been identified in Yonyou KSOA version 9.0. The issue resides in the '/kmf/save_folder.jsp' file, where the application improperly handles the 'folderid' parameter in HTTP GET requests. This lack of validation allows unauthenticated remote attackers to inject malicious SQL commands, potentially leading to unauthorized database access, data leakage, or manipulation of the database server. The vulnerability affects systems using Microsoft SQL Server.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to execute arbitrary SQL commands. This could result in unauthorized access to the database, leakage of sensitive data, tampering with data, or even gaining administrative control over the database server.

Reproduction

The vulnerability can be reproduced by sending a GET request to 'save_folder.jsp' with a crafted 'folderid' parameter that includes SQL injection payloads. This can be done using tools like SQLMap, targeting Microsoft SQL Server as the database management system.
