Validating Vulnerability Scan Results

The following sections describe how to validate vunerability scan results:

Find the CVE Information in the RedHat Database

  1. Log in to the Vulnerability scanner.
  2. Run a Vulnerability scan against FortiSIEM. See Running Vulnerability Scans against FortiSIEM.
  3. In the Vulnerability results, check for the CVE number on each vulnerability and search the noted CVE number in the Redhat database.

  4. Click the CVE number in the search results to get detailed information.
  5. Check the Affected Packages State in the Redhat CVE report for Red Hat Enterprise Linux 6 platform (note that CentOS 6 is the same as RHEL 6).
  6. In the above example CVE-2009-3560, Red Hat Enterprise Linux 6 platform is Not affected. See the following table of affected package states.

    Affected Package States

    Platform

    Package

    State

    Red Hat Enterprise Linux 7

    expat

    Not affected

    Red Hat Enterprise Linux 6

    expat

    Not affected

    Red Hat Enterprise Linux 6

    compat-epat1

    Not affected

    Red Hat Enterprise Linux 5

    xmlrpc-c

    Will not fix

  7. The Redhat database can return the following types of results:
    • Not affected – Vulnerability scanner reported a false alarm.
    • Will not fix – Redhat will not fix these vulnerabilities either due to a low CVSS score, or the platform might have reached end of support.
    • Fixed/Patch available – Redhat has already provided a fix for these vulnerabilities.
  8. You can ignore vulnerabilities that are reported as Not affected. You will need to create a vulnerability exception for CVEs that are marked as Will not fix by Redhat. For Fixed vulnerabilities, follow the instructions in Validate Redhat Fixed vulnerabilities in FortiSIEM.

Validate Redhat Fixed Vulnerabilities in FortiSIEM

  1. From the Vulnerability scanner report, find a CVE number on vulnerability and search for the number in the Redhat database.
  2. Perform the following steps if Redhat provides a patch (Security Errata):
    1. SSH to the FortiSIEM instances and the check installed packages.

      Example: search for CVE-2017-9798 in the Redhat database.

    2. Click CVE-2017-9798 and check the Redhat security errata for Red Hat Enterprise Linux 6. See the following table.

      Red Hat Security Errata

    6. In the above example, the CVE-2017-9798 patch is already available in FortiSIEM.

Mitigating Found Vulnerabilities

If the CVE number does not exist in the changelog, then follow these steps to perform a FortiSIEM OS update:

  1. If the CVE number is not included in the changelog list or the installed package is an older version, perform a FortiSIEM OS update. See FortiSIEM - OS Update Lifecycle.
  2. After the FortiSIEM OS update, repeat Step #2 in the previous section, Validate Redhat Fixed Vulnerabilities in FortiSIEM.
  3. Contact FortiSIEM support if the CVE number is not listed in the changelog after the OS update.
