Description · from the CVE record

Fumasoft Fumeng Cloud contains a SQL injection vulnerability in the AjaxMethod.ashx endpoint that allows unauthenticated remote attackers to inject arbitrary SQL through the Name parameter of the getEmpByname action without any authentication.

Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.
