Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Samsung Galaxy Apps Fixed in version 4.2.18.2. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of a staging mode. The issue lies in the ability to change the configuration based on the presence of a file in an user-controlled location. An attacker can leverage this vulnerability to escalate privileges to resources normally protected from the application. Was ZDI-CAN-5359.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a local privilege escalation vulnerability in Samsung Galaxy Apps staging mode. The application checks for a configuration file in a user-controlled location, allowing a local attacker who can place a file in that location to modify the app's configuration and escalate privileges to access resources normally protected from the application.

MitigationUpdate Samsung Galaxy Apps to version 4.2.18.2 or later. Since the vulnerability requires the attacker to first execute low-privileged code on the device, ensure devices are not compromised and restrict access to untrusted applications.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check if Samsung Galaxy Apps is installed
    Navigate to Settings > Apps on the Samsung device and look for Samsung Galaxy Apps in the application list, or check the app drawer for the Galaxy Apps icon
    Affected if Samsung Galaxy Apps is present on the device
  2. Determine the installed version of Samsung Galaxy Apps
    In Settings > Apps > Samsung Galaxy Apps, tap on App info or the three-dot menu to view the Version or Version name field. Compare this version number to the affected range of versions earlier than 4.2.18.2
    Affected if The installed version is lower than 4.2.18.2
  3. Check if staging mode is enabled
    Open Samsung Galaxy Apps, access the app settings or configuration menu, and look for an option labeled 'Staging mode' or 'Developer staging mode' to see if it is turned on
    Affected if Staging mode is enabled in the app settings

Your environment is affected if Samsung Galaxy Apps version is lower than 4.2.18.2 AND staging mode is currently enabled on the device
