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
F5 FirePass 5.4 through 5.5.1 does not properly enforce host access restrictions when a client uses a single integer (dword) representation of an IP address ("dotless IP address"), which allows remote authenticated users to connect to the FirePass administrator console and certain other network resources.

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 confidence

F5 FirePass SSL VPN versions 5.4 through 5.5.1 fail to properly enforce host-based access restrictions when clients connect using a single integer (dword) representation of an IP address instead of the standard dotted decimal notation (dotless IP). This allows authenticated users to bypass configured access controls and connect to the administrator console and other restricted network resources.

MitigationUpgrade FirePass to a version beyond 5.5.1 that addresses this vulnerability, or implement compensating network-level controls to restrict administrative interface access regardless of IP address representation format.

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. Determine FirePass SSL VPN version
    Log into the FirePass management interface and navigate to the System > Software Management page, or run 'tmsh show /sys version' via CLI to retrieve the installed software version.
    Affected if The installed version is 5.4.x (any minor release 0-9) or 5.5.x (specifically 5.5 or 5.5.1).
  2. Verify host-based access restrictions exist
    In FirePass admin console, navigate to Access Policy > Network Access > ACLs or the host check configuration section. Review whether any IP-based access control lists or host-based restrictions are defined.
    Affected if Host-based access controls are configured (the bypass only affects environments where such restrictions are in place).
  3. Test for dotless IP bypass
    Attempt to reach the FirePass administrator console or restricted resources using the integer (dword) representation of an IP address instead of dotted decimal notation (for example, use 3232235777 instead of 192.168.1.1 in the URL). Compare the access result to a standard dotted decimal request.
    Affected if Access is granted using the integer IP representation when it would be denied using standard dotted decimal notation, indicating the access control bypass is present.

You are affected if your FirePass version is 5.4.x, 5.5, or 5.5.1 AND host-based access controls are configured AND the dotless IP format bypasses those controls.
