Vulnerability Note VU#342303

Pandora iOS app does not properly validate SSL certificates

Original Release date: 28 Mar 2017 | Last revised: 13 Apr 2017

Overview

The Pandora iOS app fails to properly validate SSL certificates provided by HTTPS connections, which may enable an attacker to conduct man-in-the-middle (MITM) attacks.

Description

CWE-295: Improper Certificate Validation - CVE-2017-3194

Pandora is a streaming music service. On iOS devices, the Pandora 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.

Impact

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.

Solution

Apply an update

Pandora has released iOS app version 8.3.2 which addresses this issue. Affected users should update their Pandora app as soon as possible.

Do not use affected versions of the application

The features and services provided by the application are likely accessible via the Pandora web site. By using a web browser to access those resources, you may avoid situations where SSL is not validated.

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.
