Administrator takeover via predictable password-reset tokens
Published Aug 7, 2024 · Updated Aug 8, 2024
Password-reset weakness in Journyx 11.5.4 allows remote attackers to take over the administrator account through a predictable token. The reset flow XORs the user ID and current epoch with a key assembled from two hard-coded strings and the user ID, then Base64-encodes the result. Exploitation requires a known username and enabled self-service reset; the documented default installation username removes the unknown UUID, enabling a roughly 50,000-token search to set a new administrator password.
