The remote web server may be affected by multiple vulnerabilities.
According to its banner, the version of Apache 2.4 installed on the
remote host is a version prior to 2.4.10. It is, therefore, affected
by the following vulnerabilities :
- A flaw exists in the 'mod_proxy' module that may allow
an attacker to send a specially crafted request to a
server configured as a reverse proxy that may cause
the child process to crash. This could potentially
lead to a denial of service attack. (CVE-2014-0117)
- A flaw exists in the 'mod_deflate' module when request
body decompression is configured. This could allow a
remote attacker to cause the server to consume
significant resources. (CVE-2014-0118)
- A flaw exists in the 'mod_status' module when a
publicly accessible server status page is in place.
This could allow an attacker to send a specially
crafted request designed to cause a heap buffer
- A flaw exists in the 'mod_cgid' module in which CGI
scripts that did not consume standard input may be
manipulated in order to cause child processes to
hang. A remote attacker may be able to abuse this
in order to cause a denial of service.
- A flaw exists in WinNT MPM versions 2.4.1 to 2.4.9 when
using the default AcceptFilter. An attacker may be able
to specially craft requests that create a memory leak in
the application and may eventually lead to a denial of
service attack. (CVE-2014-3523)
Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.
