Executive brief
Frappe, a web application framework, contains a security flaw that allows any registered user to modify onboarding records. This means an unauthorized individual could change setup steps or configuration data intended for new users, potentially disrupting the onboarding process or altering system guidance. The issue has been resolved in the latest software update.
Technical details
An Insecure Direct Object Reference (IDOR) vulnerability exists in the 'update_onboarding_step' function of the Frappe framework. Due to improper access control (CWE-284), the application fails to validate if the requesting user has the appropriate permissions to modify a specific Onboarding Step record. A remote attacker with low-privileged authenticated access can exploit this by sending crafted network requests to modify any field within these records. This could lead to unauthorized data modification of system onboarding flows. The vulnerability is addressed in version 16.17.4.
