The CVE-2024-32523 vulnerability in InventoryGui arises from improper handling of the `GuiStorageElement` in graphical user interfaces. This flaw allows attackers to duplicate items by exploiting the way the library manages item stacks and their associated storage metadata. When a player interacts with a specific sequence of GUI elements, the underlying code fails to properly validate and synchronize the item state between the player’s inventory and the internal GUI storage. This state desynchronization creates a race condition where the same item stack can be manipulated to appear in both the GUI and the player’s inventory simultaneously. Consequently, by performing a rapid double-click or specific drag-and-drop actions, a malicious user can trick the plugin into believing the original item still exists in the GUI while a copy is successfully moved to their personal inventory, leading to item duplication.
Platform: Minecraft Plugins
Version: <=1.6.1-SNAPSHOT
Vulnerability: Item Duplication
Severity: Moderate
date: 2024-04-02
Prediction: Patched 2024-04-09
What Undercode Say:
git clone https://github.com/Phoenix616/InventoryGui.git cd InventoryGui git checkout 27a52ef grep -r "GuiStorageElement" src/
// Example vulnerable interaction pattern gui.addElement(new GuiStorageElement(storage, index)); // Missing state validation on click
How Exploit:
1. Attacker opens a vulnerable GUI.
2. Rapidly clicks a `GuiStorageElement`.
3. Drags item to inventory.
4. Original item remains, new copy created.
Protection from this CVE:
Update to version 1.6.2-SNAPSHOT.
Avoid using `GuiStorageElement`.
Implement item state validation.
Impact:
Item duplication economy break.
Server inventory corruption.
Unintended resource inflation.
