A valid, authenticated user may be able to trigger a denial of service of the XCC web user interface or other undefined behavior through a format string injection vulnerability in a web interface API.
A valid, authenticated XCC user with read only access may gain elevated privileges through a specifically crafted API call.
A valid XCC user's local account permissions overrides their active directory permissions under specific configurations. This could lead to a privilege escalation. To be vulnerable, LDAP must be configured for authentication/authorization and logins configured as “Local First, then LDAP”.
Improper permissions in the installer for Intel(R) Accelerated Storage Manager in Intel(R) RSTe before version 5.5.0.2015 may allow an authenticated user to potentially enable escalation of privilege via local access. L-SA-00206
Reflected XSS in web interface for Intel(R) Accelerated Storage Manager in Intel(R) RSTe before version 5.5.0.2015 may allow an unauthenticated user to potentially enable denial of service via network access.
A buffer overflow exists in the Remote Presence subsystem which can potentially allow valid, authenticated users to cause a recoverable subsystem denial of service.
A vulnerability was reported in some Lenovo Desktop models that could allow unauthorized access to the boot menu, when the "BIOS Password At Boot Device List" BIOS setting is Yes.

A buffer overflow was reported in the ReFlash module in some Lenovo Desktop products that may allow a local attacker with elevated privileges to execute arbitrary code.
A valid, authenticated XCC user with read-only permissions can modify custom user roles on other user accounts and the user trespass message through the XCC CLI. There is no exposure if SSH is disabled or if there are no users assigned optional read-only permissions.
A valid LDAP user, under specific conditions, will default to read-only permissions when authenticating into XCC. To be vulnerable, XCC must be configured to use an LDAP server for Authentication/Authorization and have the login permission attribute not defined.
Lenovo was notified of a potential denial of service vulnerability, affecting various versions of BIOS for Lenovo Desktop, Desktop - All in One, and ThinkStation, that could cause PCRs to be cleared intermittently after resuming from sleep (S3) on systems with Intel TXT enabled.
A read-only authentication bypass vulnerability was reported in the Third Quarter 2021 release of Lenovo XClarity Controller (XCC) firmware affecting XCC devices configured in LDAP Authentication Only Mode and using an LDAP server that supports “unauthenticated bind”, such as Microsoft Active Directory. An unauthenticated user can gain read-only access to XCC in such a configuration, thereby allowing the XCC device configuration to be viewed but not changed. XCC devices configured to use local authentication, LDAP Authentication + Authorization Mode, or LDAP servers that support only “authenticated bind” and/or “anonymous bind” are not affected.
