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 · unedited
A component in Kaspersky Password Manager could allow an attacker to elevate a process Integrity level from Medium to High.

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 confidence

Kaspersky Password Manager contains a vulnerability allowing a local attacker to elevate process integrity from Medium to High. This Windows integrity level escalation could permit the attacker to perform actions requiring elevated privileges, potentially bypassing user account control (UAC) restrictions.

MitigationUpdate Kaspersky Password Manager to the latest version containing the security patch. As this is a local privilege escalation, ensure systems are not exposed to untrusted local users.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if Kaspersky Password Manager is installed
    Open Windows Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like "*Kaspersky*Password*Manager*"}' in PowerShell
    Affected if Kaspersky Password Manager appears in the installed programs list
  2. Determine the installed version number
    In Programs and Features, click on Kaspersky Password Manager to view the version, or run 'Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*" | Where-Object {$_.DisplayName -like "*Kaspersky*Password*Manager*"} | Select-Object DisplayVersion' in PowerShell
    Affected if The displayed version is 9.0.2 or any version <= 9.0.1
  3. Verify the exact version via executable or application info
    Navigate to the installation directory (typically C:\Program Files\Kaspersky\Kaspersky Password Manager\ or C:\Program Files (x86)\Kaspersky\Kaspersky Password Manager\) and check the executable version by right-clicking the .exe file > Properties > Details
    Affected if The File Version or Product Version shows 9.0.2 or lower
  4. Check Windows integrity level configuration (optional context)
    Use Process Explorer or run 'Get-Process | Where-Object {$_.ProcessName -like "*KPM*" -or $_.ProcessName -like "*PasswordManager*"} | Select-Object Name, @{Name="IntegrityLevel";Expression={(Get-Acl $_.Path).IntegrityLevel}' to view process integrity levels
    Affected if KPM processes run with Medium integrity level when they should require High (indicating the vulnerable configuration is present)

A defender is affected if Kaspersky Password Manager version 9.0.2 or any version 9.0.1 and below is installed on the Windows system.
