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
server/sv_main.c in Quake3 Arena, as used in ioquake3 before r1762, OpenArena, Tremulous, and other products, allows remote attackers to cause a denial of service (network traffic amplification) via a spoofed (1) getstatus or (2) rcon request.

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

The Quake3 Arena server (sv_main.c) in ioquake3 and derivatives has an amplification vulnerability where spoofed getstatus or rcon requests cause the server to send larger responses to the forged source IP, enabling reflection/amplification DDoS attacks. The fix was implemented in ioquake3 r1762.

MitigationUpgrade affected game servers (ioquake3, OpenArena, Tremulous) to version r1762 or later, and/or implement network-level ingress filtering (anti-spoofing) to block spoofed packets at the perimeter.

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 if a Quake3-based game server is running
    Look for running processes related to ioquake3, OpenArena, or Tremulous servers. On Linux, use 'ps aux | grep -E "(ioquake3|openarena|tremulous|quake3)"' or check for processes listening on common Quake3 ports (27960, 27961).
    Affected if A server process matching ioquake3, OpenArena, or Tremulous is running and exposed to the network.
  2. Determine the installed version of the game server
    If an ioquake3 server is found, check its version by querying the server status via rcon or connecting to it. For OpenArena or Tremulous, check the installed package versions or binaries. Compare your version against the affected range (ioquake3 <= r1761, OpenArena/Tremulous all versions).
    Affected if The server version is ioquake3 r1761 or earlier, or any version of OpenArena or Tremulous.
  3. Verify network exposure of the game server port
    Check if the server is listening on UDP ports typically used by Quake3 engines (27960, 27961, or custom ports). Use 'netstat -uan' or 'ss -uan' to list UDP listeners. Confirm the server is reachable from external networks rather than only bound to localhost.
    Affected if The server is listening on a public-facing UDP port and accepts getstatus or rcon requests from untrusted sources.
  4. Test for amplification behavior
    Send a crafted getstatus request packet to the server's public IP and port using a tool like 'netcat' or 'sendip'. Observe the response size. A vulnerable server will respond with a significantly larger packet than the request.
    Affected if The server responds to a small spoofed request with a response that is substantially larger (amplification factor), enabling reflection attacks.

You are affected if you are running an ioquake3 server at version r1761 or earlier, or any version of OpenArena or Tremulous, that is exposed to the network and accepts getstatus or rcon requests from untrusted sources.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade affected game servers (ioquake3, OpenArena, Tremulous) to version r1762 or later, and/or implement network-level ingress filtering (anti-spoofing) to block spoofed packets at the perimeter.
