Detailed Description |
According to its banner, the version of Apache 2.2 installed on the remote host is older than 2.2.21. It therefore is potentially affected by a denial of service vulnerability.
An error exists in the 'mod_proxy_ajp' module that can allow specially crafted HTTP requests to cause a backend server to temporarily enter an error state. This vulnerability only occurs when 'mod_proxy_ajp' is used along with 'mod_proxy_balancer'.
* 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.
* References: http://www.apache.org/dist/httpd/CHANGES_2.2.21 http://httpd.apache.org/security/vulnerabilities_22.html
* Platforms Affected: Apache HTTP versions 2.2 prior to 2.2.21 Any operating system Any version |
Recommendation |
Upgrade to the latest version of Apache HTTP Server (2.2.21 or later), available from the Apache Software Foundation download site, http://httpd.apache.org/download.cgi -- OR -- As a workaround, ensure that the affected modules are not in use. |
