CVE-2022-23909

Description:

On Windows, the Sherpa Connector Service version 2020.2.20328.2050 contains an unquoted service path vulnerability, allowing locally authenticated users with administrative privileges to run malicious executables with LocalSystem privileges. In case of a poorly configured system, where a low privileged user could write to the "Sherpa Software" or "Sherpa Connector" directory, they could use it to elevate their privileges to LocalSystem.

Step to discover Unquoted Service Path:

image

C:>wmic service get name,displayname,pathname,startmode | findstr /i "sherpa" | findstr /i "auto" |findstr /i /v "c:\windows\" |findstr /i /v """

Sherpa Connector Service Sherpa Connector Service C:\Program Files\Sherpa Software\Sherpa Connector\SherpaConnectorService.exe Auto

C:>sc qc "Sherpa Connector Service"
