CVE-2020-9752
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 · uneditedNaver Cloud Explorer before 2.2.2.11 allows the attacker can move a local file in any path on the filesystem as a system privilege through its named pipe.
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 confidenceNaver Cloud Explorer before version 2.2.2.11 contains a local privilege escalation vulnerability in its named pipe implementation. Attackers can manipulate the application to move local files to arbitrary filesystem paths with SYSTEM-level privileges, potentially allowing full system compromise.

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 Naver Cloud Explorer installationLocate the Naver Cloud Explorer installation directory and check for executable or DLL file properties to find the installed version numberAffected if The installed version is below 2.2.2.11 or the version cannot be determined
-
Verify application is running or recently executedCheck system processes or recent activity logs for Naver Cloud Explorer (process name may include 'NaverCloudExplorer' or similar)Affected if The application is currently running or has been executed on the system
-
Inspect named pipe activityMonitor or review system logs for named pipe operations associated with Naver Cloud Explorer, particularly file move or copy operations initiated through pipe communicationAffected if named pipe operations related to file manipulation are observed from this application
-
Review file movement logsExamine system or security audit logs for file move operations executed with elevated (SYSTEM) privileges originating from Naver Cloud Explorer processesAffected if File movement operations from Naver Cloud Explorer to arbitrary paths with SYSTEM privileges are logged or detected
The system is affected if Naver Cloud Explorer version is below 2.2.2.11 and the application has been used, as the named pipe vulnerability can be exploited to achieve SYSTEM-level file manipulation.

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 data2.2.2.11
Primary remediation is to update Naver Cloud Explorer to version 2.2.2.11 or later. If immediate patching is not feasible, implement compensating controls such as restricting user access to the application and monitoring for suspicious file movement activity via the named pipe interface.
