CVSS v3.1 |
| The Remote Mount feature can potentially be abused by valid, authenticated users to make connections to internal services that may not normally be accessible to users. Internal service access controls, as applicable, remain in effect. |
| An information leak vulnerability in the SMI Set BIOS Password SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to read SMM memory. |
| 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 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 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”. |
| 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. |
| A valid, authenticated administrative user can query a web interface API to reveal the configured LDAP client password used by XCC to authenticate to an external LDAP server in certain configurations. There is no exposure where no LDAP client password is configured |
| 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. |
| An authenticated XCC user can change permissions for any user through a crafted API command. |
| An authenticated XCC user with elevated privileges can perform blind SQL injection in limited cases through a crafted API command.
This affects ThinkSystem v2 and v3 servers with XCC; ThinkSystem v1 servers are not affected. |
| An authenticated XCC user with Read-Only permission can change a different user’s password through a crafted API command.
This affects ThinkSystem v2 and v3 servers with XCC; ThinkSystem v1 servers are not affected. |
| 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. |
| An internal product security audit of Lenovo XClarity Controller (XCC) discovered that the XCC configuration backup/restore password may be written to an internal XCC log buffer if Lenovo XClarity Administrator (LXCA) is used to perform the backup/restore. The backup/restore password typically exists in this internal log buffer for less than 10 minutes before being overwritten. Generating an FFDC service log will include the log buffer contents, including the backup/restore password if present. The FFDC service log is only generated when requested by a privileged XCC user and it is only accessible to the privileged XCC user that requested the file. The backup/restore password is not captured if the backup/restore is initiated directly from XCC. |
| An authorization bypass exists in Lenovo XClarity Controller (XCC) versions prior to 3.08 CDI340V, 3.01 TEI392O, 1.71 PSI328N where a valid authenticated user with lesser privileges may be granted read-only access to higher-privileged information if 1) “LDAP Authentication Only with Local Authorization” mode is configured and used by XCC, and 2) a lesser privileged user logs into XCC within 1 minute of a higher privileged user logging out. The authorization bypass does not exist when “Local Authentication and Authorization” or “LDAP Authentication and Authorization” modes are configured and used by XCC. |
| A stored CSV Injection vulnerability was reported in Lenovo XClarity Controller (XCC) that could allow an administrative or other appropriately permissioned user to store malformed data in certain XCC server informational fields, that could result in crafted formulas being stored in an exported CSV file. The crafted formula is not executed on XCC itself and has no effect on the server. |
| OpenSLP releases in the 1.0.2 and 1.1.0 code streams have a heap-related memory corruption issue which may manifest itself as a denial-of-service or a remote code-execution vulnerability. |
| An internal product security audit discovered a UEFI SMM (System Management Mode) callout vulnerability in some ThinkSystem servers that could allow a local attacker with elevated privileges to execute arbitrary code. |
| A privilege escalation vulnerability was discovered in XCC that could allow a valid, authenticated XCC user with elevated privileges to perform command injection via specially crafted file uploads. |
| An input validation weakness was discovered in XCC that could allow a valid, authenticated XCC user with elevated privileges to perform command injection or cause a recoverable denial of service using a specially crafted file. |
