Vulnerability discussion

Information can be either unintentionally or maliciously disclosed or modified during preparation for transmission, including, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information.An example of this would be an SMTP queue. This queue may be added to a web server through an SMTP module to enhance error reporting or to allow developers to add SMTP functionality to their applications.Any modules used by the web server that queue data before transmission must maintain the confidentiality and integrity of the information before the data is transmitted.

Check content

In a command line, navigate to "<'INSTALLED PATH'>\bin". Run "httpd -M" to view a list of installed modules. If the module "mod_ssl" is not enabled, this is a finding. Review the <'INSTALLED PATH'>\conf\httpd.conf file to determine if the "SSLProtocol" directive exists and looks like the following: SSLProtocol -ALL +TLSv1.2 If the directive does not exist and does not contain "-ALL +TLSv1.2", this is a finding.

Fix text

Ensure the "SSLProtocol" is added and looks like the following in the <'INSTALLED PATH'>\conf\httpd.conf file: SSLProtocol -ALL +TLSv1.2 Ensure the "SSLEngine" parameter is set to "ON" inside the "VirtualHost" directive.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
