In SAP Commerce Cloud - versions HY_COM 1905, HY_COM 2005, HY_COM2105, HY_COM 2011, HY_COM 2205, COM_CLOUD 2211, a locked B2B user can misuse the forgotten password functionality to un-block his user account again and re-gain access if SAP Commerce Cloud - Composable Storefront is used as storefront, due to weak access controls in place. This leads to a considerable impact on confidentiality and integrity.
The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.

It is common for an application to have a mechanism that provides a means for a user to gain access to their account in the event they forget their password. Very often the password recovery mechanism is weak, which has the effect of making it more likely that it would be possible for a person other than the legitimate system user to gain access to that user’s account. Weak password recovery schemes completely undermine a strong password authentication scheme. This weakness may be that the security question is too easy to guess or find an answer to (e.g. because the question is too common, or the answers can be found using social media). Or there might be an implementation weakness in the password recovery mechanism code that may for instance trick the system into e-mailing the new password to an e-mail account other than that of the user. There might be no throttling done on the rate of password resets so that a legitimate user can be denied service by an attacker if an attacker tries to recover their password in a rapid succession. The system may send the original password to the user rather than generating a new temporary password. In summary, password recovery functionality, if not carefully designed and implemented can often become the system’s weakest link that can be misused in a way that would allow an attacker to gain unauthorized access to the system.
