CVE-2023-38294: Certain software builds for the Itel Vision 3 Turbo Android device contain a vulnerable pre-installed app with a package name of com.transsion.autotest.factory (versionCode='7', versionName='1.8.0(220310_1027)') that allows local third-party apps to execute arbitrary shell commands in its context (system user) due to inadequate access control. No permissions or special privileges are necessary to exploit the vulnerability in the com.transsion.autotest.factory app. No user interaction is required beyond installing and running a third-party app. The vulnerability allows local apps to access sensitive functionality that is generally restricted to pre-installed apps, such as programmatically performing the following actions: granting arbitrary permissions (which can be used to obtain sensitive user data), installing arbitrary apps, video recording the screen, wiping the device (removing the user's apps and data), injecting arbitrary input events, calling emergency phone numbers, disabling apps, accessing notifications, and much more. The confirmed vulnerable software build fingerprints for the Itel Vision 3 Turbo device are as follows: Itel/F6321/itel-S661LP:11/RP1A.201005.001/GL-V92-20230105:user/release-keys, Itel/F6321/itel-S661LP:11/RP1A.201005.001/GL-V86-20221118:user/release-keys, Itel/F6321/itel-S661LP:11/RP1A.201005.001/GL-V78-20221101:user/release-keys, Itel/F6321/itel-S661LP:11/RP1A.201005.001/GL-V64-20220803:user/release-keys, Itel/F6321/itel-S661LP:11/RP1A.201005.001/GL-V61-20220721:user/release-keys, Itel/F6321/itel-S661LP:11/RP1A.201005.001/GL-V58-20220712:user/release-keys, and Itel/F6321/itel-S661LP:11/RP1A.201005.001/GL-V051-20220613:user/release-keys. This malicious app sends a broadcast Intent to the receiver component named com.transsion.autotest.factory/.broadcast.CommandReceiver with the path to a shell script that it creates in its scoped storage directory. Then the com.transsion.autotest.factory app will execute the shell script with "system" privileges.
The exploitability of CVE-2023-38294 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-2023-38294 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-2023-38294, 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-2023-38294, 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: 0.043% (probability of exploit)
EPSS Percentile: 12.0%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 88.0% of others.
