Successfully Write Path to uevent_helper But Can NOT Root!
I found a world wide write vulnerability in a new model of Huawei. (Android 4.4.2)
And successfully write a path "/data/local/tmp/exploit.sh" to /sys/kernel/uevent_helper
Here is the problem, after I write the path to uevent_helper,nothing happened.
I mean,the device should run "/data/local/tmp/exploit.sh" ,but it didn't.
I've tried toggle bluetooth,wifi etc. still nothing happened.
I'm sure I didn't miss the "chmod 777 /data/local/tmp/exploit.sh" part.
did I miss something or the uevent_helper trick just dosen't work in Android 4.4.2 ?
