CVE-2019-10987
In WebAccess/SCADA Versions 8.3.5 and prior, multiple out-of-bounds write vulnerabilities are caused by a lack of proper validation of the length of user-supplied data.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.65%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
