Vulnerabilidades

A potential buffer overflow vulnerability was reported in some Lenovo ThinkSystem and ThinkStation products that could allow a local attacker with elevated privileges to execute arbitrary code.

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 command injection vulnerability was identified in SMM/SMM2 and FPC that could allow an authenticated user with elevated privileges to execute system commands when performing a specific administrative function.

ThinkSystem SR670V2 servers manufactured from approximately June 2021 to July 2023 were left in Manufacturing Mode which could allow an attacker with privileged logical access to the host or physical access to server internals to modify or disable Intel Boot Guard firmware integrity, SPS security, and other SPS…

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 can change permissions for any user through a crafted API command.

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 valid, authenticated user with limited privileges may be able to use specifically crafted web management server API calls to execute a limited number of commands on SMM v1, SMM v2, and FPC that the user does not normally have sufficient privileges to execute.

An unauthenticated denial of service vulnerability exists in the SMM v1, SMM v2, and FPC management web server which can be triggered under crafted conditions. Rebooting SMM or FPC will restore access to the management web server.

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 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 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 buffer overflow in the WMI SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to execute arbitrary code.

An information leak vulnerability in SMI Handler used to configure platform settings over WMI in some Lenovo models may allow an attacker with local access and elevated privileges to read SMM memory.

An information leak vulnerability in the Smart USB Protection SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to read SMM memory.

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.

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.

A buffer overflow exists in the Remote Presence subsystem which can potentially allow valid, authenticated users to cause a recoverable subsystem denial of service.

An authentication bypass vulnerability was discovered in an internal service of the Lenovo Fan Power Controller2 (FPC2) and Lenovo System Management Module (SMM) firmware during an that could allow an unauthenticated attacker to execute commands on the SMM and FPC2. SMM2 is not affected.

An authentication bypass vulnerability was discovered in the web interface of the Lenovo Fan Power Controller2 (FPC2) and Lenovo System Management Module (SMM) firmware that could allow an unauthenticated attacker to execute commands on the SMM and FPC2. SMM2 is not affected.

The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad T460p, BIOS versions up to R07ET90W, and T470p, BIOS versions up to R0FET50W, which may allow for unauthorized access.

A potential vulnerability in the SMI callback function used in Legacy USB driver using passed parameter without sufficient checking in some Lenovo ThinkPad models may allow arbitrary code execution.
