NOTE: the vendor says "Not sure if this qualifies as security issue (probably not)." (CVE-2016-4070) Impact BIG-IP, BIG-IQ, and Enterprise Manager products are not vulnerable in default configurations. However, if custom PHP files are created by leveraging the URL encode methods mentioned in the CVE description, systems may become vulnerable to denial-of-service (DoS) attacks. Security Issue Status F5 Product Development has assigned ID 591447 (BIG-IP), ID 596111 (BIG-IQ), and ID 596113 (Enterprise Manager) to this vulnerability.
