Proxy File '.pac' Request to Public IP Address

Medium Nessus Network Monitor Plugin ID 7206


This host is configured to use proxy settings issued by a public IP.


Proxy auto-config files, or PAC files provide the ability to auto configure proxy settings for your browser, including the ability to configure proxy settings on a per URL basis. Recent traffic from this host indicates it has requested a '.pac' file from a remote web server. In the past, malicious software has been known to use these files to perform Man-in-the-Middle attacks against affected systems.


Ensure this configuration is intended. If not, correct or disable the proxy settings on the remote host.
