CVE-2017-4928
The flash-based vSphere Web Client (6.0 prior to 6.0 U3c and 5.5 prior to 5.5 U3f) i.e. not the new HTML5-based vSphere Client, contains SSRF and CRLF injection issues due to improper neutralization of URLs.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
