CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in InventoryTransaction->findResultItem() when processing specially crafted InventoryTransactionPackets. A remote attacker can send specially crafted InventoryTransactionPackets to cause a denial of service.
