The remote proxy server is affected by a denial of service
According to its banner, the version of Squid running on the remote
host is 2.x or 3.x prior to 3.1.23 / 3.2.6 / 18.104.22.168. The included
'cachemgr.cgi' tool reportedly lacks input validation, which could be
abused by any client able to access that tool to perform a denial of
service attack on the service host.
Note this fix is a result of an incomplete fix for CVE-2012-5643.
Further note that Nessus did not actually test for this issue, but
instead has relied on the version in the server's banner.
See also :
Either upgrade to Squid version 3.1.23 / 3.2.6 / 22.214.171.124 or later, or
apply the vendor-supplied patch.
Alternatively, restrict access to this CGI or limit CGI memory
consumption via the host web server's configuration options.
