A serious vulnerability was discovered in the Shazam app that could expose the location of Android and iOS users. Thankfully, Shazam has fixed the bug before exploitation in the wild.
Shazam Vulnerability Exposing Users’ Location
Reportedly, the British security researcher Ashley King discovered a serious security vulnerability in the Shazam app. Exploiting this bug could allow an attacker to steal users’ location data.
Describing the details in a blog post, the researcher revealed that he found two different bugs in the Shazam app. Identified as CVE-2019-8791 and CVE-2019-8792, the vulnerabilities could even turn into a zero-click vulnerability for both Android and iOS platforms. The bugs remained underrated to achieve a qualification for bounty.
Specifically, the issue existed in the way Shazam handled web links. As stated in the post,
To exploit the bug, an attacker merely had to send a malicious link to the target user, clicking on which would open Shazam app. As soon as Shazam app would execute the link via webview, the attacker could steal victim’s location information.
Bug Patched Already
The researcher found this vulnerability back in December 2018. However, the bug only received a patch by March 2019 as Shazam underwent an acquisition by Apple.
Moreover, it took more months for Apple to decide whether the bug report qualifies for a bounty or not. Given all this scenario, the researcher has disclosed the bug only recently. Nonetheless, Shazam users don’t have to worry about their security as the issue has since been addressed.
