CVE-2018-15809
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 · uneditedAccuPOS 2017.8 is installed with the insecure "Authenticated Users: Modify" permission for files within the installation path. This may allow local attackers to compromise the integrity of critical resource and executable files.
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 confidenceAccuPOS 2017.8 is installed with overly permissive file system ACLs, granting 'Authenticated Users' Modify permissions on files within the installation path. This allows any local user with a valid account to tamper with executables and configuration files, potentially enabling code execution or application 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.
-
Find AccuPOS installation directoryCheck for AccuPOS installation in common paths: C:\Program Files\AccuPOS\, C:\Program Files (x86)\AccuPOS\, or look in Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for AccuPOS entry to locate the InstallLocationAffected if AccuPOS version 2017.8 is found installed on the system
-
Verify AccuPOS versionRight-click the AccuPOS executable (typically Accupos.exe in the installation folder), select Properties, and check the File Version or Product Version on the Details tabAffected if The installed version is exactly 2017.8
-
Inspect ACLs on installation folderRight-click the AccuPOS installation folder, select Properties, go to the Security tab, click Advanced. Check the permissions listed for each user/groupAffected if The entry for 'Authenticated Users' shows Allow for Modify (or Write) permissions on the folder or its files
If AccuPOS version 2017.8 is installed AND the installation directory grants Authenticated Users Modify or Write permissions, the environment is affected by this vulnerability.

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 dataRestrict file permissions on the AccuPOS installation directory to require Administrator or specific service account access for modification, removing the Authenticated Users Modify permission. Verify the application functions correctly after hardening.
