Akamai's Response to CVE-2015-1635

In response to the vulnerability discussed in the Microsoft disclosure at https://technet.microsoft.com/library/security/MS15-034, Akamai has analyzed its production servers and has determined it is not running any version of the software that is susceptible to the vulnerability.
 
Akamai has created a permanent rule for the Trustwave® ModSecurity® Core Rule Set (CRS) and Akamai® Kona Rule Set (KRS) rule to help protect customer servers from attacks that exploit this vulnerability. This rule (3000031) is available on Luna Control System and can be manually added to your Firewall policy using the following actions:
 
For Existing Firewall Policies using CRS v1.6.1:
  1. Access Luna Control Center and the Web Application Firewall page (CONFIGURE >> WAF Configuration).
  2. On the Web Application Firewall page, select the WAF Configuration version with which you would like to work.
  3. On the resulting Web Application Firewall Configuration page, edit the Firewall Policy for which you would like to enable rule 3000031.
  4. On the resulting Edit Firewall Policy page, click the Next button.
  5. On the resulting Application Layer Controls page, in the 1.6.1 Rule Set list, scroll to rule 3000031 and select its check box.

6. Click the Next button, and continue clicking it on any subsequent pages until you reach the final page.

7. Click Finish to finish updating the Firewall Policy.


For Existing Firewall Policies using KRS v1.0:
  1. Access Luna Control Center and the Web Application Firewall page (CONFIGURE >> WAF Configuration).
  2. On the Web Application Firewall page, select the WAF Configuration version with which you would like to work.
  3. On the resulting Web Application Firewall Configuration page, edit the Firewall Policy for which you would like to enable rule 3000031.
Be aware, unless you created your Firewall Policy on or after April 1, 2015, you must upgrade to the latest KRS version for rule 3000031 to become available to your Firewall Policy; a KRS 1.0 Update Requirednotification will appear on the Web Application Firewall Configuration page for each affected Policy. In addition, if you choose to create a new version of a WAF Configuration or Firewall Policy from an existing one created prior to April 1, 2015, you must be certain to upgrade KRS in the new version.
 
Complete the upgrade procedures in the Upgrading the KRS, Version 1.0 Rule Set section of the Kona Site Defender User Guide available in Luna Control Center (Support >> User and Developer Guides >> Kona Security Solutions) in order to proceed with enabling the rule.
4. On the resulting Edit Firewall Policy page, click the Next button.
5. On the resulting Application Layer Controls page, in the KRS 1.0 Rule Set list, scroll to rule 3000031 and select its check box.

6.      Click the Next button, and continue clicking it on any subsequent pages until you reach the final page.
