Acer Portal Android Application - MITM SSL Certificate Vulnerability


"Acer BYOCâ??s suite of Apps allows you to start building your own cloud
to connect and share everything in your life between your smart
devices and your computer. Freely manage anything from photos to
movies to documents all over the cloud!"

"Register your Acer ID, and activate your Acer BYOC apps today."



The Acer Portal Android application (version and below),
installed by the manufacturer on all Acer branded Android devices,
does not validate the SSL certificate it receives when connecting to
the mobile application login server.


An attacker who can perform a man in the middle attack may present a
bogus SSL certificate which the application will accept silently.
Usernames, passwords and sensitive information could be captured by an
attacker without the user's knowledge.
