CVE-2022-0928Network attack vector

Stored script execution via unsanitized tax type

Published Mar 11, 2022 · Updated Aug 2, 2024

Stored XSS in Microweber before 1.2.12 allows remote authenticated users to execute script in another user's browser via tax type input. The shop/save_tax_item callback passes request data to TaxManager::save without the XSS middleware, allowing the type field to be stored without neutralization. Administrative access is required to save the payload, and a victim must view the stored tax data for the script to run in that browser.
