CVE-2024-39063Public exploitNetwork attack vector

Administrative account creation via unvalidated GET request

Published Jul 9, 2024 · Updated Aug 2, 2024

Cross-site request forgery in LimeSurvey 6.5.12 and earlier allows remote attackers to create an administrative account through a crafted link. The userManagement/applyedit action accepts state-changing account fields from GET requests without enforcing POST or validating YII_CSRF_TOKEN. Exploitation requires a logged-in administrator to follow the link, after which the attacker controls the new administrative account.
