Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Teeworlds versions 0.7.x through 0.7.4 Teeworlds version 0.7.5 is not affected, so the range can be simplified to versions prior to 0.7.5.

Corrected version: Teeworlds versions prior to 0.7.5

Description The issue is related to insufficient input validation in the CServer::SendMsg function, located in engine/server/server.cpp. This allows remote attackers to shut down the server, resulting in a denial of service.

Recommendations For Teeworlds versions prior to 0.7.5, update to version 0.7.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the CServer::SendMsg function until a patch is available.
