An unauthenticated attacker may exploit a scenario where a Hashed Message Authentication Code (HMAC) credential, extracted from a system missing specific security patches, is reused in a replay attack against a different system. Even if the target system is fully patched, successful exploitation could result in complete system compromise, affecting confidentiality, integrity, and availability.

This vulnerability exists in Shilpi Client Dashboard due to implementation of inadequate authentication mechanism in the login module wherein access to any users account is granted with just their corresponding mobile number. A remote attacker could exploit this vulnerability by providing mobile number of targeted user, to obtain complete access to the targeted user account.

IBM webMethods Integration 10.15 could allow an authenticated user to create scheduler tasks that would allow them to escalate their privileges to administrator due to missing authentication.

LDAP users on IBM Spectrum Virtualize 8.5 which are configured to require multifactor authentication can still authenticate to the CIM interface using only username and password. This does not affect local users with MFA configured or remote users authenticating via single sign-on. IBM X-Force ID: 247033.

IBM PowerSC 1.3, 2.0, and 2.1 uses single-factor authentication which can lead to unnecessary risk of compromise when compared with the benefits of a dual-factor authentication scheme. IBM X-Force ID: 275114.

The Admin Classic Bundle provides a Backend UI for Pimcore. `AdminBundle\Security\PimcoreUserTwoFactorCondition` introduced in v11 disable the two factor authentication for all non-admin security firewalls. An authenticated user can access the system without having to provide the two factor credentials. This issue has been patched in version 1.2.2.

In JetBrains TeamCity before 2023.05 authentication checks were missing – 2FA was not checked for some sensitive account actions
