CVE-2022-28543
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 · uneditedPath traversal vulnerability in Samsung Flow prior to version 4.8.07.4 allows local attackers to read arbitrary files as Samsung Flow permission.
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 confidenceA path traversal vulnerability in Samsung Flow versions prior to 4.8.07.4 allows a local attacker with Samsung Flow permissions to read arbitrary files on the device by manipulating file path inputs (e.g., using '../' sequences) to escape the intended directory boundaries and access sensitive system or user data.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Samsung Flow is installedCheck device application list or package manager for Samsung Flow app. On Android, you can use adb shell pm list packages or check Settings > Apps for Samsung Flow.Affected if Samsung Flow application is found on the device
-
Determine installed Samsung Flow versionAccess app version information through device Settings > Apps > Samsung Flow > App info, or use adb shell dumpsys package <package_name> to retrieve version details.Affected if A version number is returned from the device
-
Compare version against vulnerable rangeCompare your installed version to the affected range: versions prior to 4.8.07.4 are vulnerable. For example, versions like 4.7.x, 4.6.x, or any version below 4.8.07.4 are within the affected range.Affected if Installed version is less than 4.8.07.4 (e.g., 4.8.0.0, 4.7.5.2, 4.6.1.0)
-
Confirm Samsung Flow file access feature existsVerify the app has file transfer or document access functionality that processes file path inputs. Check if the app includes features for accessing or transferring files between devices.Affected if The app includes file path handling capabilities that could process traversal sequences like '../'
User is affected if Samsung Flow is installed with a version number lower than 4.8.07.4 and the app processes file path inputs.
