CVE-2024-48645Network attack vector

Game modification via unchecked function-update packets

Published Oct 21, 2024 · Updated Oct 21, 2024

Missing authorization in arm32x Command Block IDE 0.4.9 and earlier allows remote attackers to modify game function files. The global APPLY_FUNCTION packet receiver in CommandBlockIDE#onInitialize merges and applies client-supplied function payloads without checking the sender's permission level. The path exists only when the mod is installed on a dedicated server; changed functions can alter in-game behavior but cannot execute arbitrary host code, and client-only installations are unaffected.
