CVE-2016-10136: An issue was discovered on BLU R1 HD devices with Shanghai Adups software. The content provider named com.adups.fota.sysoper.provider.InfoProvider in the app with a package name of com.adups.fota.sysoper allows any app on the device to read, write, and delete files as the system 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. This allows a third-party app to read, write, and delete files owned by the system user. The third-party app can modify the /data/system/users/0/settings_secure.xml file to add an app as a notification listener to be able to receive the text of notifications as they are received on the device. This also allows the /data/system/users/0/accounts.db to be read which contains authentication tokens for various accounts on the device. The third-party app can obtain privileged information and also modify files to obtain more privileges on the device.
The exploitability of CVE-2016-10136 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2016-10136 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2016-10136, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2016-10136, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.044% (probability of exploit)
EPSS Percentile: 15.45%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 84.55% of others.
