CVE-2006-4657
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 · uneditedPanda Platinum Internet Security 2006 10.02.01 and 2007 11.00.00 stores service executables under the product's installation directory with weak permissions, which allows local users to obtain LocalSystem privileges by modifying (1) WebProxy.exe or (2) PAVSRV51.EXE.
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 confidencePanda Platinum Internet Security stores service executables (WebProxy.exe and PAVSRV51.EXE) in the product's installation directory with weak permissions that allow local users to modify these files. When the services restart, the modified executables run with LocalSystem privileges, enabling 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.
-
Identify installed version of Panda Platinum Internet SecurityCheck the Windows Registry under HKLM\SOFTWARE\Panda Software\Setup or look in Add/Remove Programs for the exact version numberAffected if Version matches 2006_10.02.01 or 2007_11.00.00 exactly as listed in affected versions
-
Locate the product installation directoryCheck the typical installation path C:\Program Files\Panda Software\Panda Platinum Internet Security or verify the path from the registry keyAffected if Installation directory exists and contains the product
-
Verify presence of WebProxy.exeNavigate to the installation directory and confirm WebProxy.exe existsAffected if File exists in the installation directory - this is one of the vulnerable service executables
-
Verify presence of PAVSRV51.EXENavigate to the installation directory and confirm PAVSRV51.EXE existsAffected if File exists in the installation directory - this is one of the vulnerable service executables
-
Check file permissions on service executablesRight-click each executable, go to Properties > Security tab, and verify if Users or non-admin accounts have Write or Modify permissions to these filesAffected if Non-admin users have Write or Modify permissions to WebProxy.exe or PAVSRV51.EXE - this allows privilege escalation when services restart with LocalSystem privileges
User is affected if Panda Platinum Internet Security version 2006_10.02.01 or 2007_11.00.00 is installed AND the service executables (WebProxy.exe, PAVSRV51.EXE) exist AND non-admin users have write/modify permissions to these executables.

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 service executables to prevent unauthorized modification by non-admin users, or upgrade to a patched version of the software that addresses this vulnerability.
