Polipo Local Web Root Restriction Bypass Vulnerability Vulnerability Scan


Vulnerability Scan Summary
Checks for local web root restriction bypass vulnerability in Polipo

Detailed Explanation for this Vulnerability Test

Synopsis :

The remote web server may expose files outside the local web root.

Description :

The remote host is running the Polipo caching web proxy. In addition to
caching web pages, the software also functions as a web server for
providing access to documentation, cached pages, etc.

The built-in web server in the installed version of Polipo fails to
filter directory traversal sequences from requests. By exploiting this
issue, a possible hacker may be able to retrieve files located outside the
local web root, subject to the rights of the userid under which
Polipo runs.
