CBC Gem Android & iOS Applications - Unencrypted Analytics (CVE-2019-19464)


"Watch hundreds of shows on demand and stream live news and sports, all for free. With CBC Gem, you can stream current episodes and past seasons of comedies, dramas, documentaries and more."



The CBC Gem Android & iOS applications (Android version 9.24.0 and below, iOS version 9.24.0 and below) sends potentially sensitive information such as device model & resolution, mobile carrier, days since first use, days since last use, total number of app launches, number of app launches since upgrade, and previous app session length, unencrypted to both first and third party sites (Adobe Marketing Cloud, ScorecardResearch).


An attacker who can monitor network traffic could capture potentially sensitive information about the user's device and viewing habits without their knowledge.
