Vulnerability discussion

Data mining is the analysis of large quantities of data to discover patterns and is used in intelligence gathering. Failure to prevent attacks launched against organizational information from unauthorized data mining may result in the compromise of information.Injection attacks allow an attacker to inject code into a program or query or inject malware into a computer to execute remote commands that can read or modify a database or change data on a website. These attacks include buffer overrun, XML, JavaScript, and HTML injections.Compliance requires the ALG to have the capability to prevent code injections. Examples include Web Application Firewalls (WAFs) or database application gateways.

Check content

If the BIG-IP Core does not perform content filtering as part of the traffic management functionality for virtual servers, this is not applicable. When content filtering is performed as part of the traffic management functionality, verify the BIG-IP Core is configured as follows: Verify Virtual Server(s) in the BIG-IP LTM module are configured with an ASM policy to prevent code injection attacks from being launched against application objects, including, at a minimum, application URLs, and application code and application. Navigate to the BIG-IP System manager >> Local Traffic >> Virtual Servers >> Virtual Servers List tab. Select Virtual Servers(s) from the list to verify. Navigate to the Security >> Policies tab. Verify that "Application Security Policy" is Enabled and "Policy" is set to use an ASM policy to prevent code injection attacks from being launched against application objects, including, at a minimum, application URLs and application code. If the BIG-IP Core is not configured to prevent code injection attacks from being launched against application objects, including, at a minimum, application URLs and application code, this is a finding.

Fix text

If the BIG-IP Core performs content filtering as part of the traffic management functionality, configure the BIG-IP Core as follows: Configure a policy in the BIG-IP ASM module to prevent code injection attacks from being launched against application objects, including, at a minimum, application URLs and application code. Apply ASM policy to the applicable Virtual Server(s) in BIG-IP LTM module to prevent code injection attacks from being launched against application objects, including, at a minimum, application URLs and application code.

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.
