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
Race condition in the cut-through proxy feature in Cisco Firewall Services Module (FWSM) Software 3.x before 3.2(28) and 4.x before 4.1(15) allows remote attackers to cause a denial of service (device reload) via certain matching traffic, aka Bug ID CSCuj16824.

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

Race condition vulnerability in the cut-through proxy feature of Cisco FWSM Software allows remote attackers to cause denial of service via device reload by sending certain matching traffic. Affects versions 3.x before 3.2(28) and 4.x before 4.1(15).

MitigationUpgrade Cisco FWSM Software to version 3.2(28) or later for 3.x branches, or 4.1(15) or later for 4.x branches to patch the race condition vulnerability.

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 Cisco FWSM device
    Log into the parent Cisco switch or router and run 'show module' or 'show chassis' to confirm the Firewall Services Module is present
    Affected if The device is not a Cisco FWSM module (this CVE does not apply)
  2. Get FWSM software version
    From the switch/router console, execute 'show module <slot> details' or connect to the FWSM and run 'show version' to retrieve the installed software version
    Affected if Version begins with 3.x and is below 3.2(28), or begins with 4.x and is below 4.1(15)
  3. Check cut-through proxy configuration
    From FWSM exec mode, run 'show running-config' and search for 'cut-through' or 'cut-through proxy' configuration statements. Also check 'show service-policy' for cut-through proxy policy assignments
    Affected if Cut-through proxy feature is explicitly configured and active on any interface
  4. Verify traffic matching for cut-through proxy
    Review 'show conn' output and access-lists to identify traffic flows that match any configured cut-through proxy policies. Run 'show service-policy interface <name>' to see active cut-through proxy service policies
    Affected if Cut-through proxy policies are applied to interfaces and matching traffic flows exist

The environment is affected only if the device is a Cisco FWSM running version 3.x before 3.2(28) or 4.x before 4.1(15) AND the cut-through proxy feature is actively configured and processing traffic.
