ShoreTel Mobility Client for iOS and Android, version 9.1.3.109 and earlier, fails to properly validate SSL certificates provided by HTTPS connections, which may enable an attacker to conduct man-in-the-middle (MITM) attacks.
CWE-295**: Improper Certificate Validation -******CVE-2016-6562
On iOS and Android devices, the ShoreTel Mobility Client app fails to properly validate SSL certificates provided by HTTPS connections, which means that an attacker in the position to perform MITM attacks may be able to obtain sensitive account information such as login credentials.
An attacker on the same network as the iOS device may be able to view or modify network traffic that should have been protected by HTTPS, which may lead to the exposure of sensitive account information, including login credentials.
Apply an update.
ShoreTel has released version 9.1.5.104 for all devices to address the vulnerability.
If you are unable to update your application, please see the following workarounds:
Avoid untrusted networks
Avoid using untrusted networks, including public WiFi. Using your device on an untrusted network increases the chance of falling victim to a MITM attack.
