To demonstrate how an attacker could easily steal masses of user data, a simple bash script could be used to generate a sample list of URLs. For example, accessing would show a photo of a fake driver’s license. However, by incrementing the value in the URL, it is possible to view or listen to other media messages shared between other users. When a recipient receives an SMS text containing a media URL link sent from this app, the text message appears as follows:īrowsing to would allow the recipient to view the voice message. The following demonstrates how an attacker could abuse this weakness to view other users’ media content without authorization: This obviously impacts the confidentiality of media content sent via this application. As a result, a malicious user could potentially access any media files sent via this service and also any that are sent in the future. Furthermore, when sharing media files, a link will be generated regardless of the recipient having the app installed. In addition, the URL link was sequential (hexadecimal) and predictable. SpiderLabs found that accessing the link was possible without any authentication or authorisation, meaning that any user with the link is able to view the content. The user could then click on the link and view the media file via a browser. However, if the recipient does not have the GO SMS Pro app installed, the media file is sent to the recipient as a URL via SMS. If the recipient has the GO SMS Pro app on their device, the media would be displayed automatically within the app. The GO SMS Pro application, like other messenger apps, allows users to send private media to other users as demonstrated below. It is unclear which other versions are affected but we believe this is likely to affect previous and potentially future versions as well. This weakness was discovered on GO SMS Pro v7.91. This means any sensitive media shared between users of this messenger app is at risk of being compromised by an unauthenticated attacker or curious user. This exposure includes private voice messages, video messages, and photos. The GO SMS Pro application is a popular messenger app with over 100 million downloads and was discovered to publicly expose media transferred between users of the app.
