Detailsinfo

A vulnerability was found in BLU Advance and R1 HD (unknown version). It has been classified as critical. This affects an unknown code block. The manipulation with an unknown input leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered on BLU Advance 5.0 and BLU R1 HD devices with Shanghai Adups software. The com.adups.fota.sysoper app is installed as a system app and cannot be disabled by the user. In the com.adups.fota.sysoper app's AndroidManifest.xml file, it sets the android:sharedUserId attribute to a value of android.uid.system which makes it execute as the system user, which is a very privileged user on the device. The app has an exported broadcast receiver named com.adups.fota.sysoper.WriteCommandReceiver which any app on the device can interact with. Therefore, any app can send a command embedded in an intent which will be executed by the WriteCommandReceiver component which is executing as the system user. The third-party app, utilizing the WriteCommandReceiver, can perform the following actions: call a phone number, factory reset the device, take pictures of the screen, record the screen in a video, install applications, inject events, obtain the Android log, and others. In addition, the com.adups.fota.sysoper.TaskService component will make a request to a URL of http://rebootv5.adsunflower.com/ps/fetch.do where the commands in the String array with a key of sf in the JSON Object sent back by the server will be executed as the system user. Since the connection is made via HTTP, it is vulnerable to a MITM attack.

The bug was discovered 11/15/2016. The weakness was shared 01/13/2017 (Website). The advisory is shared at kryptowire.com. This vulnerability is uniquely identified as CVE-2016-10138 since 01/13/2017. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 59 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at SecurityFocus (BID 96853†). The entries VDB-95287, VDB-95288 and VDB-95290 are related to this item. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
