[原文]Directory traversal vulnerability in webfs before 1.20 allows remote attackers to read arbitrary files via .. (dot dot) sequences in a Hostname header.


[CNNVD]WebFS HTTP服务程序信息泄露漏洞(CNNVD-200311-082)

        
        webfs是一款轻量级HTTP服务程序。
        webfs没有正确处理用户提交的主机名请求,远程攻击者可以利用这个漏洞获得系统敏感信息,如路径信息。
        当程序使用虚拟主机时,如果远程客户端请求中 指定".."为主机名,可导致返回文档ROOT目录中的目录列表或文件信息。攻击者可以结合其他漏洞对系统进行进一步攻击。

- 漏洞讨论

An information disclosure vulnerability has been discovered in Webfs HTTP server. The problem occurs due to insufficient sanitization of user-supplied hostnames when accessing virtual hosts. As a result, an attacker may be capable of viewing the contents of directories and files outside of the established web root.

This issue may only exist if the server has been configured to use virtual hosting.

- 漏洞利用

No exploit required.

- 解决方案

Debian has released a security advisory (DSA-392-1) and fixes which address this and other issues in WebFS. Users are advised to upgrade their installations as soon as possible.
