What it is

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. Attackers can exploit UNION-based SQL injection techniques against the Microsoft SQL Server backend to extract, disclose, and modify database contents, with potential for further compromise of the underlying server. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.
