CVE-2020-7811
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 · uneditedSamsung Update 3.0.2.0 ~ 3.0.32.0 has a vulnerability that allows privilege escalation as commands crafted by attacker are executed while the engine deserializes the data received during inter-process communication
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 confidenceSamsung Update versions 3.0.2.0 through 3.0.32.0 contains an insecure deserialization vulnerability in its inter-process communication mechanism. During IPC, the application deserializes data without proper validation, allowing an attacker to craft malicious serialized objects that execute arbitrary commands with elevated privileges.

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 Update is installedLocate Samsung Update on the system by checking common installation directories, Start Menu, or using system inventory tools to find the applicationAffected if Samsung Update software is present on the system
-
Determine the installed version numberAccess the version information through the application properties, About dialog, or system registry entries where application version data is storedAffected if The exact installed version number cannot be determined or retrieved
-
Compare version against affected rangeReview the installed version against the vulnerable range: 3.0.2.0 through 3.0.32.0Affected if The installed version falls within >= 3.0.2.0 and <= 3.0.32.0
-
Confirm IPC functionality is in useObserve whether the Samsung Update application is running and actively performing update operations that trigger inter-process communicationAffected if The application is actively processing update operations through its IPC mechanism
You are affected if Samsung Update is installed and the running version is between 3.0.2.0 and 3.0.32.0 inclusive.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Samsung Update to a version beyond 3.0.32.0 (vendor patched version). If immediate patching is not feasible, implement application whitelisting and restrict IPC communication permissions to limit exploitation surface.
