Vulnerability Note VU#582497
Multiple Android applications fail to properly validate SSL certificates
Multiple Android applications fail to properly validate SSL certificates provided by HTTPS connections, which may allow an attacker to perform a man-in-the-middle (MITM) attack.
When communicating via HTTPS, an application should validate the SSL chain to be sure that the certificate produced by the site was provided by a trusted root certificate authority (CA). Multiple Android applications fail to properly validate SSL certificates. Additional information can be found in the CERT Oracle Secure Coding Standard for Java:
DRD19-J. Properly verify server certificate on SSL/TLS
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.
