CVE-2020-7862
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 · uneditedA vulnerability in agent program of HelpU remote control solution could allow an authenticated remote attacker to execute arbitrary commands This vulnerability is due to insufficient input santization when communicating customer process.
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 confidenceA command injection vulnerability exists in the HelpU remote control agent program. An authenticated attacker can send specially crafted input through the customer process communication channel that, due to insufficient input sanitization, allows execution of arbitrary operating system commands on the target system.

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 HelpU componentsCheck system for installed HelpU software by reviewing installed programs list. On Windows, use Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product' or check registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'Helpu' or 'HelpU'. On Linux, check package manager listings.Affected if Any Helpu Helpuftclient, Helpu Helpuftserver, Helpu Helpuserver, or Helpu Helpviewer is installed on the system.
-
Determine installed version of HelpU componentsOnce a HelpU component is identified, locate its version. Check the program's properties in Programs and Features, examine the executable file properties (right-click the main .exe file > Properties > Details tab), or review version info in the program's installation directory.Affected if The installed version matches 3.0.0.0 for Helpuftclient or Helpuftserver, 1.0.0.2 for Helpuserver, or 2018.5.21.0 for Helpuviewer.
-
Verify customer process communication channel is activeAffected if The HelpU service is running and its communication channel is accessible to authenticated users.
You are affected if any HelpU component (Helpuftclient, Helpuftserver, Helpuserver, or Helpuviewer) is installed at exactly the affected version AND the service is running with its communication channel accessible to authenticated attackers.

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 dataImplement proper input validation and sanitization on all user-supplied data before using it in system calls. Use parameterized interfaces or safe API functions that avoid shell interpretation of user input.
