Vulnerability Note VU#1680209

AppsGeyser generates Android applications that fail to properly validate SSL certificates

Original Release date: 19 Dec 2014 | Last revised: 07 Jan 2015


AppsGeyser generates applications that fail to properly validate SSL certificates.


AppsGeyser is an online tool that generates Android applications. At the time of publication of this vulnerability note, the AppsGeyser website claims to have generated over 1.3 million Android applications. The applications that are generated by AppsGeyser include code that disables SSL certificate validation for HTTPS traffic.


When a victim is using an application generated by AppsGeyser, an attacker on the same network as the Android device may be able to view or modify network traffic that should have been protected by HTTPS. The impact varies based on what the application is doing. Possible outcomes include credential stealing or arbitrary code execution.


Regenerate affected Android applications

The AppsGeyser application generator has been updated to correctly validate SSL certificates. Any applications that were created before December 24, 2014 should be regenerated.
