CVE-2018-4847
A vulnerability has been identified in SIMATIC WinCC OA Operator iOS App (All versions < V1.4).
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description

Insufficient protection of sensitive information (e.g. session key for accessing server) in Siemens WinCC OA Operator iOS app could allow an attacker with physical access to the mobile device to read unencrypted data from the app's directory.
