Flaw detail
The researcher of Medigate company is flying benefit riverside discovers 3 flaw in afore-mentioned equipment:
? CWE-287 of incorrect flaw of identity test and verify (CVE-2018-10597) : CVSS V3 grading is 8.3 minutes, allow to visit memory and keep the memory of end equipment without the aggressor of identity test and verify.

? Information divulges flaw CWE-200 (CVE-2018-10599) : CVSS V3 grading is 6.4 minutes, allow to read the memory that takes target facility without the aggressor of identity test and verify.
