A weakness has been identified in Yonyou KSOA 9.0. Affected by this vulnerability is an unknown functionality of the file /kmf/save_folder.jsp of the component HTTP GET Parameter Handler. Executing a manipulation of the argument folderid can lead to sql injection. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

This vulnerability is classified as medium severity with a CVSS score of 5.5. Organizations should address this issue in their patch cycle to mitigate potential exploitation risks. The attack vector is network-based, and the complexity is low, making it easier for attackers to execute. As of now, there is no known public exploit confirmed for this vulnerability.

Risk to organizations includes potential unauthorized access to the database through SQL injection, which can lead to data leakage or corruption. Given the remote exploitability and low attack complexity, organizations should prioritize patching immediately.

The vendor has not yet provided a patch for this vulnerability, which increases the urgency for organizations to implement their own defenses against potential exploitation.

Monitoring network traffic for unusual activity and implementing web application firewall rules can help mitigate the risk until a patch is available.
