Microweber is a drag-and-drop online store management system from the Microweber community in the United States. The system includes modules for adding products, images, etc. An integer overflow vulnerability exists in versions of Microweber prior to 1.3. The vulnerability stems from the fact that the application allows large characters to be inserted into input fields such as “Town, ZIP, State, Address and Additional Info fields”, which can be exploited to cause a denial of service.
