HTTP Proxy Open gopher:// Request Relaying
Info Nessus Plugin ID 11305
SynopsisThe HTTP proxy accepts gopher:// requests.
DescriptionGopher 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 so that it refuses gopher requests.
