    Hello THE_BLUE 

    all CVE's that F5 documents in its Security Advisory series specifically refer to vulnerabilities that affect/compromise F5 products only, in this case BIG-IP. 
    Any application that runs on-top of the BIG-IP, like an HTTP portal, will not be covered. 

    So, unless xxx.com resolves to an IP address on the BIG-IP that allows Configuration Utility access (webI or SSH), it shoudn't be considered as an attack vector.

Thank you

So, unless xxx.com resolves to an IP address on the BIG-IP that allows Configuration Utility access (webI or SSH), it shoudn't be considered as an attack vector. 

this mean if xxx.com secure by waf and it's mapped to xxx server . this will not have affect to WAF because there is no relation between xxx.com and WAF ssh .

so this vulnerability will be compromised by users who have access to WAF , right?

Correct

Correct again - user needs to be logged to the WAF, and send a packet that contains the specific URL (undisclosed so far) that opens the attack vector.
