CVE-2018-4847: A vulnerability has been identified in SIMATIC WinCC OA Operator iOS App (All versions < V1.4).

A vulnerability has been identified in SIMATIC WinCC OA Operator iOS App (All versions < V1.4). 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. Siemens provides mitigations to resolve the security issue.

Security readout for executives and security teams

This issue affects Siemens SIMATIC WinCC OA Operator iOS App versions before V1.4. Sensitive app data, including a server session key, may be stored unencrypted. An attacker needs physical access to the mobile device to read the app directory, making urgency dependent on mobile device control and operational access value. Exposure is limited to environments using the affected Siemens iOS operator app, especially where mobile devices access industrial control systems. Risk increases if devices are shared, unmanaged, lost, stolen, or lack strong mobile device controls. Treat this as a targeted operational access risk rather than an internet-scale emergency. Prioritize sites where the iOS app connects to production WinCC OA systems or where mobile devices are weakly managed. Mitigation focus: Identify all devices running SIMATIC WinCC OA Operator iOS App before V1.4.; Upgrade affected app installations to V1.4 or later per Siemens guidance.; Apply Siemens advisory mitigations where immediate upgrade is not possible..

Insertion of Sensitive Information into Externally-Accessible File or Directory

Insertion of Sensitive Information into Externally-Accessible File or Directory represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
