(CVE-2016-2099) Impact o An attacker requires privileged access to a dynamically generated XML file to exploit one of the affected components of the BIG-IP APM system. Additionally, an attacker must have access to a privileged user in order to download a malformed XML file on the system to trigger the exploit. o The XML file accessed by the affected component of BIG-IP Analytics is internal and inaccessible to external sources, thus limiting the vulnerability exposure. Security Advisory Status F5 Product Development has assigned IDs 598950 and 599360 (BIG-IP), ID 599815 (Enterprise Manager), and ID 595939 (ARX) to this vulnerability.
