标题:Vmware Spring Framework 跨站脚本漏洞 (CVE-2020-5398)Description:Vmware Spring Framework是美国威睿（Vmware）公司的一套开源的Java、JavaEE应用程序框架。该框架可帮助开发人员构建高质量的应用。 Pivotal Software Spring Framework 5.2.3之前的5.2.x版本、5.1.13之前的5.1.x版本和5.0.16之前的5.0.x版本中存在跨站脚本漏洞。远程攻击者可通过实施反射型文件下载（RFD）攻击利用该漏洞获取敏感信息。
Description
CVE-2020-5398 - RFD(Reflected File Download) Attack for Spring MVC
介绍
# CVE-2020-5398 - RFD(Reflected File Download) Attack for Spring MVC
> In Spring Framework, versions 5.2.x prior to 5.2.3, versions 5.1.x prior to 5.1.13, and versions 5.0.x prior to 5.0.16, an application is vulnerable to a reflected file download (RFD) attack when it sets a “Content-Disposition” header in the response where the filename attribute is derived from user supplied input.
## Using
1.
```
./gradlew bootrun
```
Listen on `127.0.0.1:8080`.
2.
```
$ curl 'http://127.0.0.1:8080/?filename=sample&contents=Hello,%20World' --dump-header -
HTTP/1.1 200
Content-Disposition: attachment; filename="sample.txt"
Content-Type: application/octet-stream
Content-Length: 12
Date: Fri, 17 Jan 2020 05:41:08 GMT
Hello, World
```
Start download `sample.txt` file.
