(CVE-2016-3093) Impact The Object-Graph Navigation Language (OGNL) used by the Apache Struts framework uses an improper implementation of cache to store method references. When BIG-IP AAM is provisioned, a remote attacker can attempt to initiate a denial-of-service (DoS) attack. Security Issue Status F5 Product Development has assigned ID 600461 (BIG-IP) to this vulnerability. To determine if your release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases or hotfixes that address the vulnerability, refer to the following table: Product Versions known to be vulnerable Versions known to be not vulnerable Severity Vulnerable component or feature BIG-IP LTM None 12.0.0 - 12.1.0 Not vulnerable None 11.4.0 - 11.6.1 11.2.1 10.2.1 - 10.2.4 BIG-IP AAM 12.0.0 - 12.1.0 11.4.0 - 11.6.1 Medium Configuration utility BIG-IP AFM None 12.0.0 - 12.1.0 Not vulnerable None 11.4.0 - 11.6.1 BIG-IP Analytics None 12.0.0 - 12.1.0 Not vulnerable None 11.4.0 - 11.6.1 11.2.1 BIG-IP APM None 12.0.0 - 12.1.0 Not vulnerable None 11.4.0 - 11.6.1 11.2.1 10.2.1 - 10.2.4 BIG-IP ASM None 12.0.0 - 12.1.0 Not vulnerable None 11.4.0 - 11.6.1 11.2.1 10.2.1 - 10.2.4 BIG-IP DNS None 12.0.0 - 12.1.0 Not vulnerable None BIG-IP Edge Gateway None 11.2.1 Not vulnerable None 10.2.1 - 10.2.4 BIG-IP GTM None 11.4.0 - 11.6.1 Not vulnerable None 11.2.1 10.2.1 - 10.2.4 BIG-IP Link Controller None 12.0.0 - 12.1.0 Not vulnerable None 11.4.0 - 11.6.1 11.2.1 10.2.1 - 10.2.4 BIG-IP PEM None 12.0.0 - 12.1.0 Not vulnerable None 11.4.0 - 11.6.1 BIG-IP PSM None 11.4.0 - 11.4.1 Not vulnerable None 10.2.1 - 10.2.4 BIG-IP WebAccelerator None 11.2.1 Not vulnerable None 10.2.1 - 10.2.4 BIG-IP WOM None 11.2.1 Not vulnerable None 10.2.1 - 10.2.4 ARX None 6.2.0 - 6.4.0 Not vulnerable None Enterprise Manager None 3.1.1 Not vulnerable None FirePass None 7.0.0 Not vulnerable None BIG-IQ Cloud None 4.0.0 - 4.5.0 Not vulnerable None BIG-IQ Device None 4.2.0 - 4.5.0 Not vulnerable None BIG-IQ Security None 4.0.0 - 4.5.0 Not vulnerable None BIG-IQ ADC None 4.5.0 Not vulnerable None BIG-IQ Centralized Management None 5.0.0 Not vulnerable None BIG-IQ Cloud and Orchestration None 1.0.0 Not vulnerable None F5 iWorkflow None 2.0.0 Not vulnerable None LineRate None 2.5.0 - 2.6.1 Not vulnerable None F5 MobileSafe None 1.0.0 Not vulnerable None F5 WebSafe None 1.0.0 Not vulnerable None Traffix SDC None 5.0.0 Not vulnerable None 4.0.0 - 4.4.0 Vulnerability Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Versions known to be not vulnerable column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists.
