CVE-2019-18642Network attack vector

Unauthenticated account takeover via unchecked profile user ID

Published Jan 7, 2021 · Updated Aug 5, 2024

Authorization bypass in Rock RMS before 8.6 allows remote attackers to take over accounts through the profile update feature. The profile update handler accepts a tampered sequential user ID without confirming that the requester owns the targeted profile, permitting an arbitrary account email address to be replaced. No authentication is required; after redirecting a target's email address, an attacker can complete password reset and control that account, including an administrator account.
