Share on:Description
VTech Storio Max before 56.D3JM6 allows remote command execution via shell metacharacters in an Android activity name. It exposes the storeintenttranslate.x service on port 1668 listening for requests on localhost.

The requests also match those of the HTTP protocol and can be triggered on any web page rendered on the device by requesting resources stored at an http://127.0.0.1:1668/ URI as demonstrated by the http://127.0.0.1:1668/dacdb70556479813fab2d92896596eef?’;pingexample.org’ URL.
