CVE-2021-25054Public exploitNetwork attack vector

Authenticated SQL injection via unsanitized did parameter

Published Jan 10, 2022 · Updated Aug 3, 2024

SQL injection in Wow-Company WPcalc 2.1 and earlier allows remote authenticated users to execute SQL through the did parameter. WPcalc inserts the unsanitized did value into a SQL statement on the plugin administrative page, allowing crafted expressions to alter the query. An authenticated WordPress session and access to that page are required; successful exploitation executes attacker-controlled SQL with the site database privileges.
