Summary

The Bank of Tokyo-Mitsubishi UFJ for Android vulnerable to SSL/TLS downgrade attack

Details

The Bank of Tokyo-Mitsubishi UFJ for Android may be exploited by SSL/TLS downgrade attack. The Bank of Tokyo-Mitsubishi UFJ for Android provided by The Bank of Tokyo-Mitsubishi UFJ, Ltd. tries to communicate with a server via TLS v1.2. However, when a response from the server indicates SSL v3.0, communication is conducted via SSL v3.0 (CWE-757). As a result, the application may be exploited by POODLE attack. CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade') https://cwe.mitre.org/data/definitions/757.html Reo Yoshida reported this vulnerability to JPCERT/CC, and JPCERT/CC coordinated with The Bank of Tokyo-Mitsubishi UFJ, Ltd.
