Analysis Summary
An improper enforcement of message integrity during transmission in a communication channel vulnerability is found in the Siemens SCALANCE W700 and W1700 wireless communication devices.
Under certain conditions, the integrity of EAPOL-key messages might not be checked, leading to a decryption oracle. This could be exploited by an attacker within range of the access point, which could allow the abuse of the vulnerability to access confidential data. CVE-2018-14526 has been assigned to this vulnerability.

Affected Vendors
Siemens
Affected Products
- SCALANCE W700 Versions 6.3 and prior
- SCALANCE W1700 Versions 1.0 and prior
Remediation
Apply the following updates:
- SCALANCE W700: Update to v6.4 or later
- SCALANCE W1700: Update to v1.1 or later
Additionally: - Whenever possible, use AES-CCMP instead of TKIP in the WPA/WPA2 networks. This can be configured for both the SCALANCE W-700 and W-1700 families over the Web Based Management (web server).
- Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
- Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available.
