Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92 and 7.3 GA through update 35 allows a time-based one-time password (TOTP) to be used multiple times during the validity period, which allows attackers with access to a user’s TOTP to authenticate as the user.
The product implements an authentication technique, but it skips a step that weakens the technique.
