CVE-2020-35557
An issue in MB connect line mymbCONNECT24, mbCONNECT24 and Helmholz myREX24 and myREX24.virtual in all versions through v2.11.2 allows a logged in user to see devices in the account he should not have access to due to improper use of access validation.
Does this matter?
Lower severity and a low EPSS score (1.00%). Track it; it rarely justifies an emergency change on its own.
