CVE-2021-24294Public exploitNetwork attack vector

Administrator account creation via stored log XSS

Published May 24, 2021 · Updated Aug 3, 2024

Stored XSS in DSGVO All in one for WP before 4.0 allows remote attackers to execute scripts in an administrator's browser. The dsgvoaio_write_log AJAX action stores unsanitized POST parameters with update_option() and later renders them unescaped on the Log page. Exploitation requires an administrator to view the poisoned log; the script can use that session to create a rogue administrator account.
