What to do

The vendor has published a fix. Version details are below where the sources state them.

Steps

Written by AI from the record

Check whether you run a Call of Duty server and record its exact game version.
If it is Call of Duty 1.5b or earlier, United Offensive 1.51b or earlier, or Call of Duty 2 1.3 or earlier, take it out of public access until remediated.
No exact fixed version is confirmed in the available findings; obtain the vendor-recommended update or replacement from the remediation advisory.

What it is

From the CVE record

Buffer overflow in (1) Call of Duty 1.5b and earlier, (2) Call of Duty United Offensive 1.51b and earlier, and (3) Call of Duty 2 1.3 and earlier allows remote attackers to execute arbitrary code via a long map argument to the "callvote map" command.

In plain language

Written by AI from the record

Older Call of Duty servers—Call of Duty through 1.5b, United Offensive through 1.51b, or Call of Duty 2 through 1.3—can be taken over remotely, so small businesses running these old game servers should act.

A remotely triggered buffer overflow in the `callvote map` command permits arbitrary code execution through an overly long map argument.

What is it

This is a flaw in an old multiplayer game-server command that can let an outsider send an unusually long instruction and take control of the server. It is like a visitor using an oversized form to jam a reception desk, then gaining access to the office behind it.

Who is affected

This matters to you if you run a Call of Duty multiplayer server, including older base-game, United Offensive, or Call of Duty 2 installations. It is a risk when an attacker can reach the game server over the network and submit the affected map-vote command.

How urgent is it

Attackers can remotely take over an unpatched server by abusing its map-vote command. There is no confirmed active exploitation or public exploit code in the findings, so this is an amber, near-term remediation issue rather than an emergency—but do not leave an affected public server exposed.

What to do — in detail

Confirm the installed game and server version, then identify whether the server accepts player map votes through the callvote map command. The affected releases are Call of Duty 1.5b and earlier, Call of Duty United Offensive 1.51b and earlier, and Call of Duty 2 1.3 and earlier. The supplied findings do not identify an exact fixed version, so use the vendor remediation advisory to obtain the appropriate supported update, or retire/replace the legacy server if a supported upgrade is unavailable.

If patching is delayed, remove the server from internet access or restrict access to trusted players, and disable map voting if that can be done without disrupting operations. Watch for unexpected game-server crashes, unusual map-vote requests, and unexplained changes to server files or processes. CISA has not assigned a KEV remediation due date because this CVE is not listed in KEV.

Technical context

CVSS v2 is 7.5 (High): AV:N/AC:L/Au:N/C:P/I:P/A:P. The issue is a buffer overflow (NVD-CWE-Other) reachable through a long map argument supplied to the callvote map command, enabling remote arbitrary code execution. CISA KEV does not list this CVE, and no public exploit code is on record. EPSS predicts a 10.1% likelihood (95th percentile) and is flat; this is predictive evidence, not confirmation of exploitation. Exploit maturity is therefore unproven publicly.

This is a general assessment based on public vulnerability data. It does not account for your specific infrastructure — when in doubt, consult a security specialist.
