Title: Uhuru Mobile Davfi Multiple VulnerabilitiesProduct: Uhuru
MobileEnterprise: Nov'IT
Hello,
Multiple vulnerabilities were found in the Uhuru Mobile ROM. These
vulnerabilities were detailed in a blogpost [1].
Vulnerability #1 - Whitelist of executable applications
bypass:----------------------------The Android kernel was modified and
"hardened". A feature was implemented to only allow a whitelist of
binaries to be executed. This can be bypassed by using, for example,
the LD_PRELOAD environment variable.
Vulnerability #2 - Embedded kernel vulnerable to CVE-2013-6282 (local
root)----------------------------The embedded Android kernel version
is 3.4.0, which is vulnerable to CVE-2013-6282. This can be exploited
to obtain root rights.
Vulnerability #3 - Embedded kernel vulnerable to CVE-2013-4787 (master
key)----------------------------The embedded Android kernel is
vulnerable to CVE-2013-4787. This can be exploited to bypass the APK
signature system of Android.
Vulnerability #4 - Local escape shell
vulnerability----------------------------When the phone is encrypted,
it uses the passcode entered by the user to decrypt/encrypt files. The
passcode entered by the user is executed as root inside a shell
command without being filtered. An attacker just have to reboot the
phone, and once the phone asks for the passcode, enter the payload aka
s/Please enter your passcode/Please enter your payload/ . This can be
exploited to gain local code execution as root.
Eric Filiol, the main creator of the project, responded [2] (in
french) to the reported vulnerabilities.
