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
Ingate Firewall before 4.6.0 and SIParator before 4.6.0 do not log truncated (1) ICMP, (2) UDP, and (3) TCP packets, which has unknown impact and remote attack vectors; and do not log (4) serial-console login attempts with nonexistent usernames, which might make it easier for attackers with physical access to guess valid login credentials while avoiding detection.

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

Ingate Firewall and SIParator before version 4.6.0 fail to log truncated ICMP, UDP, and TCP packets, and do not log serial-console login attempts with nonexistent usernames. This logging gap allows attackers to conduct network reconnaissance or brute-force login attempts (particularly with physical console access) without leaving detectable traces in the logs.

MitigationUpgrade to Ingate Firewall or SIParator version 4.6.0 or later. Until then, implement supplemental network monitoring and physical access controls to detect the undirected attack activity that would otherwise go unlogged.

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. Identify the installed product and version
    Access the Ingate device administrative interface or use the device's command-line interface to retrieve the firmware/software version. Look for version information in the system status, about page, or running-config.
    Affected if The product is Ingate Firewall or SIParator and the version is 4.5.2 or earlier (any version <= 4.5.2).
  2. Verify serial console login logging
    Access the serial console of the Ingate device. Attempt a login with a username that does not exist in the user database. Check the system logs to see if this failed login attempt was recorded.
    Affected if The failed login attempt with a nonexistent username does NOT appear in the logs (the logging gap exists).
  3. Verify truncated packet logging for ICMP
    Send truncated ICMP packets (for example, ping packets with the 'don't fragment' flag set and a size exceeding the path MTU) toward the Ingate device. Inspect the device logs to confirm whether these truncated packets were logged.
    Affected if Truncated ICMP packets are NOT recorded in the logs.
  4. Verify truncated packet logging for UDP and TCP
    Send truncated UDP or TCP packets (packets with incomplete headers or payload) to the Ingate device. Review the logging or audit trail to determine if these packets were captured and logged.
    Affected if Truncated UDP or TCP packets are NOT recorded in the logs.

You are affected if running Ingate Firewall or SIParator version 4.5.2 or earlier and serial console logins with nonexistent usernames or truncated packets are not appearing in your logs.

From vendor data
Upgrade available Upgrade to a release after 4.5.2
Interim mitigation

Upgrade to Ingate Firewall or SIParator version 4.6.0 or later. Until then, implement supplemental network monitoring and physical access controls to detect the undirected attack activity that would otherwise go unlogged.
