When APM is deployed as an OAuth Resource Server, APM becomes a client application to an external OAuth authorization server. In certain cases when communication between the BIG-IP APM and the OAuth authorization server is lost, APM may not display the intended message in the failure response. (CVE-2018-15335)
Impact
BIG-IP APM
A vulnerable BIG-IP APM system may not include the intended diagnostic content in its failure response.
BIG-IP (LTM, AAM, AFM, Analytics, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator), BIG-IQ, Enterprise Manager, F5 iWorkflow, and Traffix SDC
There is no impact; these F5 products are not affected by this vulnerability…
