| | Добрый день дорогой АЛЛ.
в общем суть проблемы такова - у нас проведено сканирование сети и на моём сервере обноружены 2 уязвимости апача:
1)Web Server HTTP Trace/Track Method Support Cross-Site Tracing Vulnerability
Port: 80; Protocol: tcp
2)Apache Partial HTTP Request Denial of Service Vulnerability
сервер на Linux RHEL 4.2
как лечить ?
за ранее спасибо за ответ.
p.s.
вот интересный момент но я не знаю куда имено и что делать?
Your webserver supports the TRACE and/or TRACK methods. TRACE and TRACK
are HTTP methods which are used to debug web server connections.
It has been shown that servers supporting this method are subject
to cross-site-scripting attacks, dubbed XST for
"Cross-Site-Tracing", when used in conjunction with
various weaknesses in browsers.
An attacker may use this flaw to trick your
legitimate web users to give him their
credentials.
Solution: Disable these methods.
If you are using Apache, add the following lines for each virtual
host in your configuration file :
RewriteEngine on
RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
RewriteRule .* - [F]
If you are using Microsoft IIS, use the URLScan tool to deny HTTP TRACE
requests or to permit only the methods needed to meet site requirements
and policy.
If you are using Sun ONE Web Server releases 6.0 SP2 and later, add the
following to the default object section in obj.conf:
<Client method="TRACE">
AuthTrans fn="set-variable"
remove-headers="transfer-encoding"
set-headers="content-length: 34377-1"
error="501"
</Client>
If you are using Sun ONE Web Server releases 6.0 SP2 or below, compile
the NSAPI plugin located at:
