Proxy Accepts gopher:// Protocol Requests
Medium Nessus Network Monitor Plugin ID 1590
SynopsisThe proxy accepts gopher:// requests.
DescriptionThe proxy accepts gopher:// requests. Gopher is an old network protocol which predates HTTP and is nearly unused today. As a result, gopher-compatible software is generally less audited and more likely to contain security bugs than others. By making gopher requests, an attacker may evade your firewall settings by making connections to port 70 or may even exploit arcane flaws in this protocol to gain more privileges on this host (see the attached CVE ID for such an example).
SolutionReconfigure your proxy to refuse gopher protocol requests.
