Detailed Description The version of the Apache Web server is older than 2.0.46. The Apache 2.x versions prior to 2.0.46 have multiple vulnerabilities like the following:

1. A vulnerability in the authentication module for Apache 2.0.40 through 2.0.45 may allow remote attackers to cause a denial of service (failed Basic authentication with valid usernames and passwords) under certain conditions.
2. A vulnerability in the mod_dav module of Apache 2.0.37 through 2.0.45 may allow remote attackers to crash the server or even to remotely execute arbitrary code under the strict conditions

mod_dav is an open-source Apache module that provides Distributed Authoring and Versioning (DAV) capabilities to the Apache HTTP Server. More information is available at
http://www.webdav.org/mod_dav/ .

* Note: This check solely relied on the version number of the remote Web server to assess this vulnerability, so this might be a false positive.
