CVE-2025-2028
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 · uneditedLack of TLS validation when downloading a CSV file including mapping from IPs to countries used ONLY for displaying country flags in logs
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 confidenceThe application downloads a CSV file containing IP-to-country mappings over HTTPS without validating the TLS certificate, allowing man-in-the-middle attackers to supply malicious country mapping data that gets displayed as flags in application logs.

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 Checkpoint Log Server versionRun 'cpstat -g' or check the system dashboard for the exact software version of the Checkpoint Log Server installationAffected if The installed version is r81.10, r81.20, or r82 (any of the affected versions listed)
-
Locate the CSV download configurationSearch the Checkpoint Log Server configuration files for any entries related to IP-to-country mapping, country flags, or CSV download URL (commonly found under $FWDIR/conf or $CPDIR/conf directories)Affected if A configuration entry exists that specifies an HTTPS URL for downloading an IP-to-country CSV mapping file
-
Verify certificate validation settingsExamine the configuration files or registry entries controlling the CSV download feature for any TLS/certificate validation settings, or check if validation is explicitly disabled for the download mechanismAffected if Certificate validation is disabled, set to 'none', or not configured for the IP-to-country CSV download endpoint
-
Inspect application logs for anomalous flagsReview Checkpoint Log Server logs (typically in /var/log/ or via the Log Investigator interface) for any displayed flag data that appears malformed, unexpected, or originates from suspicious IP-to-country mappingsAffected if Logs contain flag representations from country mappings that were not obtained from the legitimate source, indicating potential malicious data injection
You are affected if your Checkpoint Log Server runs version r81.10, r81.20, or r82, and the IP-to-country CSV download feature is enabled with TLS certificate validation disabled or absent.

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 TLS certificate validation (CA chain verification or certificate pinning) when downloading the CSV file to ensure the data originates from the legitimate source.
