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 confidenceThe web protection component in multiple Kaspersky consumer and small business security products (versions up to 2020) failed to adequately inform users about the threat when being redirected to an untrusted site, allowing a bypass of security warnings.

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 Kaspersky productOpen the installed Kaspersky application or go to Programs and Features in Windows to see which Kaspersky product is installed (Anti-Virus, Internet Security, Security Cloud, Small Office Security, or Total Security)Affected if The product is one of the listed affected products (Kaspersky Anti-Virus, Internet Security, Security Cloud, Small Office Security, or Total Security)
-
Check installed version numberOpen the Kaspersky application, go to Settings, and look for the About or Support section which displays the version number; alternatively, right-click the Kaspersky icon in the system tray and select AboutAffected if The version is 2020 or lower for Anti-Virus, Internet Security, Security Cloud, or Total Security; or version 7 or lower for Small Office Security
-
Confirm web protection is enabledOpen Kaspersky settings and verify that Web Protection, Web Anti-Virus, or Network Traffic Scanning is turned ON (the exact name varies by product)Affected if The web protection component is enabled and active in the product settings
-
Compare version against affected rangesIf the exact version is known, compare it to the affected range: any version up to and including 2020 for the 2020-line products, or any version up to and including 7 for Small Office SecurityAffected if The installed version falls within or below the affected version threshold for that product line
You are affected if you have any of the listed Kaspersky products (Anti-Virus, Internet Security, Security Cloud, Small Office Security, or Total Security) at version 2020 or earlier (or Small Office Security 7 or earlier) with the web protection component enabled.

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 dataUpdate affected Kaspersky products to version 2020 or later to receive the patched web protection component that properly warns users about redirects to untrusted sites.
