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
Cisco Emergency Responder 8.6 and 9.2 allows remote attackers to cause a denial of service (CPU consumption) by sending malformed UDP packets to the CERPT port, aka Bug ID CSCtx38369.

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

A denial of service vulnerability in Cisco Emergency Responder versions 8.6 and 9.2 allows remote attackers to send malformed UDP packets to the CERPT port, causing excessive CPU consumption and service degradation.

MitigationApply available Cisco patches for this vulnerability or implement network-level filtering/firewall rules to restrict unsolicited UDP traffic to the CERPT port.

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. Verify Cisco Emergency Responder installation
    Query system inventory, installed software, or look for CER-related processes and directories on the server
    Affected if Cisco Emergency Responder software is present on the system
  2. Confirm installed version is 8.6 or 9.2
    Use the Cisco Emergency Responder CLI command 'show version' or check the product version through the administrative interface
    Affected if The version returned is exactly 8.6 or exactly 9.2
  3. Verify CERPT service is running and listening
    Check for the CERPT process or use netstat/ss to verify the CERPT UDP port is in LISTENING state
    Affected if The CERPT UDP service is running and accepting connections
  4. Assess network exposure of CERPT port
    Review firewall rules and network ACLs to determine if the CERPT UDP port is accessible from network segments outside the trusted internal network
    Affected if The CERPT port is reachable from untrusted or external network sources

If the system has Cisco Emergency Responder version 8.6 or 9.2 installed with the CERPT port exposed to accessible networks, the environment is vulnerable to CVE-2012-1346.
