FooSun DotNetCMS 1.0 and 2.0 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate MSSQL queries through the CityId parameter. Attackers can send GET requests to /user/City_ajax.aspx with UNION SELECT payloads in CityId, concatenated unsanitized into the sys_City query, to extract database information. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-14.
