<plugin_comment>I don't know if it is possible to detect dev versions by banner-grabbing. That is why this plugin may be not 100 % accurate. But the Nessus plugin has the same limitations.</plugin_comment>

<bug_not_affected>Apache web servers newer than 2.0.51-dev or other web servers</bug_not_affected>
<bug_vulnerability_class>Denial Of Service</bug_vulnerability_class>
<bug_description>The remote host is running an Apache web server prior 2.0.51-dev. The module mod_dav is vulnerable to a denial of service attack if a special sequence of LOCK-requests is sent. These methods have to be supported by the target system.</bug_description>
<bug_solution>If the web server and/or dav support is not used it should be de-installed or de-activated. Install the newest patch or bugfix to solve the problem or upgrade to the latest software version which is not vulnerable anymore. Additionally limit unwanted connections and communications with firewalling.</bug_solution>
