Vulnerability discussion

Remote access to the web server is any access that communicates through an external, non-organization-controlled network. Remote access can be used to access hosted applications or to perform management functions. By providing remote access information to an external monitoring system, the organization can monitor for cyber attacks and monitor compliance with remote access policies. The organization can also look at data organization wide and determine an attack or anomaly is occurring on the organization which might not be noticed if the data were kept local to the web server.

Check content

Navigate to and open /etc/haproxy/haproxy.cfg Navigate to the globals section. Verify that the globals section contains the log keyword, and that the log option contains the local0 syslog facility as its parameter. If properly configured, the globals section will contain the following: global log 127.0.0.1 local0 If the local0 syslog facility is not configured, this is a finding. Navigate to the defaults section. Verify that the defaults section contains the log keyword with the global value. Verify that an option keyword has been configured with the httplog value. If properly configured, the "globals" section will contain the following: defaults log global option httplog Navigate to and open the following files: /etc/haproxy/conf.d/30-vro-config.cfg /etc/haproxy/conf.d/20-vcac.cfg Navigate to the each frontend section. Verify that the log keyword has not been set for each frontend. If the log keyword is resent in a frontend, this is a finding. Navigate to and open /etc/rsyslog.d/vcac.conf. Review the configured syslog facilities and determine the location of the log file for the local0 syslog facility. If the local0 syslog facility does not refer to a valid log file, this is a finding. Navigate to and open the local0 syslog log file. Verify that HAProxy is logging start and stop events to the log file. If the log file is not recording HAProxy start and stop events, this is a finding.

Fix text

Navigate to and open /etc/rsyslog.d/vcac.conf. Configure the local0 syslog facility to write to an appropriate log file. Navigate to and open /etc/haproxy/haproxy.cfg. Configure the globals section with the following: log 127.0.0.1 local0 Configure the defaults section with both of the following: log global option httplog Navigate to and open the following files: /etc/haproxy/conf.d/30-vro-config.cfg /etc/haproxy/conf.d/20-vcac.cfg Navigate to each frontend section. Remove any log options from each frontend.

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.
