CVE-2022-0182Network attack vector

Stored script execution via unsanitized page parameters

Published Jan 17, 2022 · Updated Aug 2, 2024

Stored XSS in ExpressTech Systems Quiz and Survey Master before 7.3.7 allows remote authenticated users to inject arbitrary scripts. Available technical reporting states that user-controlled parameters are stored without sanitization and later emitted into a page without adequate escaping, but public records do not identify the affected parameter or handler. Low-privilege WordPress access is sufficient, and the stored payload executes in the browser of a user who visits the affected page.
