CVE-2015-2219
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 · uneditedLenovo System Update (formerly ThinkVantage System Update) before 5.06.0034 uses predictable security tokens, which allows local users to gain privileges by sending a valid token with a command to the System Update service (SUService.exe) through an unspecified 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 · high confidenceLenovo System Update (versions prior to 5.06.0034) uses cryptographically weak/predictable security tokens when authenticating requests to the SUService.exe via named pipes. A local unprivileged user can predict or brute-force these tokens and send commands with a valid token to execute code with elevated (SYSTEM) privileges, achieving local privilege escalation.

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 Lenovo System Update is installedCheck the installed programs list in Windows Control Panel > Programs and Features, or use 'wmic product get name,version' to list installed software and look for 'Lenovo System Update'Affected if Lenovo System Update appears in the installed programs list
-
Determine the installed version of Lenovo System UpdateOpen Programs and Features, find Lenovo System Update, and note the version number shown in the Version column. Alternatively, check the file properties of the executable location (typically in C:\Program Files\Lenovo\System Update\)Affected if The displayed version is 5.06.0027 or earlier, or any version prior to 5.06.0034
-
Check if SUService.exe is runningOpen Task Manager, go to the Services tab, or run 'sc query SUService' from an elevated command prompt to check if the Lenovo System Update service is activeAffected if The SUService is running or installed on the system
-
Confirm version is within vulnerable rangeCompare your installed version against the affected range. The vulnerability affects versions prior to 5.06.0034, with confirmed vulnerable versions being 5.06.0027 and earlierAffected if The installed version is 5.06.0027 or below, or any version earlier than 5.06.0034
The system is affected if Lenovo System Update version 5.06.0027 or earlier is installed, or any version prior to 5.06.0034, with the SUService.exe vulnerable component running.

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 dataApply Lenovo System Update version 5.06.0034 or later which implements proper unpredictable security tokens for named pipe authentication.
