Description

Certain software builds for the BLU View 2 and Sharp Rouvo V Android devices contain a vulnerable pre-installed app with a package name of com.evenwell.fqc (versionCode='9020801', versionName='9.0208.01' ; versionCode='9020913', versionName='9.0209.13' ; versionCode='9021203', versionName='9.0212.03') 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.evenwell.fqc 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 software build fingerprints for each confirmed vulnerable device are as follows: BLU View 2 (BLU/B131DL/B130DL:11/RP1A.200720.011/1672046950:user/release-keys, BLU/B131DL/B130DL:11/RP1A.200720.011/1663816427:user/release-keys, BLU/B131DL/B130DL:11/RP1A.200720.011/1656476696:user/release-keys, BLU/B131DL/B130DL:11/RP1A.200720.011/1647856638:user/release-keys) and Sharp Rouvo V (SHARP/VZW_STTM21VAPP/STTM21VAPP:12/SP1A.210812.016/1KN0_0_460:user/release-keys and SHARP/VZW_STTM21VAPP/STTM21VAPP:12/SP1A.210812.016/1KN0_0_530:user/release-keys). This malicious app starts an exported activity named com.evenwell.fqc/.activity.ClickTest, crashes the com.evenwell.fqc app by sending an empty Intent (i.e., having not extras) to the com.evenwell.fqc/.FQCBroadcastReceiver receiver component, and then it sends command arbitrary shell commands to the com.evenwell.fqc/.FQCService service component which executes them with "system" privileges.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.

Weakness class

CVE-2023-38290 is classified as CWE-1263: Improper Physical Access Control. The product is designed with access restricted to certain information, but it does not sufficiently protect against an unauthorized actor with physical access to these areas.
