CVE-2018-6183
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 · uneditedBitDefender Total Security 2018 allows local users to gain privileges or cause a denial of service by impersonating all the pipes through a use of an "insecurely created named pipe". Ensures full access to Everyone users group.
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 confidenceBitDefender Total Security 2018 creates named pipes with insecure permissions that grant full access to the Everyone group. Local unprivileged users can impersonate these pipes to escalate privileges to SYSTEM level or cause denial of service.

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 installed BitDefender versionOpen Control Panel > Programs and Features, or run 'wmic product get name,version' to list installed software and locate BitDefender Total SecurityAffected if Version shown is exactly 2018 (any build)
-
Locate BitDefender named pipesOpen an elevated command prompt and run 'tasklist /svc | findstr -i bitdefender' to identify running BitDefender services, then check for named pipes using a tool like Process Explorer or by enumerating \\pipe\* from a non-elevated command promptAffected if BitDefender services are running and named pipes accessible to all users exist
-
Inspect named pipe permissionsUse Sysinternals Process Explorer (right-click a BitDefender process > Properties > Security) or icacls on identified pipe objects to view the DACLAffected if The DACL grants Full Control or Write to the Everyone group or Authenticated Users on BitDefender pipes
-
Verify unprivileged pipe accessFrom a standard (non-admin) user account, attempt to connect to BitDefender pipes using a tool like pipelist from Sysinternals or custom code to call CreateFile on the pipeAffected if Non-admin user can successfully open and write to BitDefender named pipes
If BitDefender Total Security 2018 is installed with running services and its named pipes grant broad access to Everyone or authenticated users, the system is vulnerable to local privilege escalation.

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 to a current version of BitDefender that has this vulnerability patched. If upgrading is not possible, consider compensating controls such as restricting local user access or deploying an alternative endpoint security solution.
