CVE-2024-20870
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 · uneditedImproper verification of intent by broadcast receiver vulnerability in Galaxy Store prior to version 4.5.71.8 allows local attackers to write arbitrary files with the privilege of Galaxy Store.
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 · moderate confidenceGalaxy Store prior to version 4.5.71.8 contains a broadcast receiver that improperly validates incoming intent messages. A local attacker can send crafted intents to this receiver to trigger arbitrary file write operations with the elevated privileges of the Galaxy Store application.

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.
-
Identify Galaxy Store package and versionOpen Android Settings > Apps > find 'Galaxy Store' (package name typically com.sec.android.app.samsungapps or com.samsung.android.app.samsungapps). Tap on it to view the version name and version code displayed under 'App info'.Affected if The displayed version name or version code is lower than 4.5.71.8
-
Verify version via command lineConnect device via ADB and run: adb shell dumpsys package com.sec.android.app.samsungapps | grep -E 'versionName|versionCode' (or the actual package name found in step 1).Affected if The output shows a version lower than 4.5.71.8
-
Confirm vulnerable broadcast receiver existsDecompile the APK or use: adb shell pm dump com.sec.android.app.samsungapps | grep -A 20 'BroadcastRecipients' to inspect registered broadcast receivers. Look for receivers that handle intent actions related to app updates or downloads.Affected if A broadcast receiver is registered that handles incoming intents without proper validation (present in versions < 4.5.71.8)
You are affected if the installed Galaxy Store version is below 4.5.71.8, as this version range contains the broadcast receiver lacking proper intent validation.
