Cisco Issues Security Update to WebEx Android App

Last week Cisco issued a security update for their WebEx Meetings Android App to resolve a severe permissions issue.

Why Should This Issue Be Considered Important?

This is a serious security issue that could lead to information disclosure and an elevation of privilege (defined) attack. It’s present in all versions of the app that are older than version 8.5.1. As Cisco discusses in it’s security advisory this issue could be exploited by a remote attacker with no previous access to the app by tricking the user of the smartphone into downloading another app that exploits this issue within the WebEx app. If this were to happen any information and permissions/access that the WebEx app has will be then available to the malicious app.

In addition, there are no workarounds for this issue. At this time Cisco has not seen any evidence to show that this issue has been used by attackers.

How Can I Protect Myself From This Issue?
Cisco have released an updated version of the WebEx app to address this issue. The updated app is available from this link (Google Play Store). Graham Cluley’s blog post also contains one piece of further important advice to stay safe when downloading apps or app updates.

Thank you.
