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.

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.

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.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, if an attacker manages to log in to the device OS, the validation of software updates can be circumvented.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, the SMM contains weak default root credentials which could be used to log in to the device OS -- if the attacker manages to enable SSH or Telnet connections via some other vulnerability.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, the SMM web interface for changing Enclosure VPD fails to sufficiently sanitize all input for HTML tags, possibly opening a path for cross-site scripting.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, the SMM records hashed passwords to a debug log when user authentication fails.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, an internal SMM function that retrieves configuration settings is prone to a buffer overflow.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, the FFDC feature includes the collection of SMM system files containing sensitive information; notably, the SMM user account credentials and the system shadow file.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, the SMM certificate creation and parsing logic is vulnerable to several buffer overflows.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, the SMM certificate creation and parsing logic is vulnerable to post-authentication command injection.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, a field in the header of SMM firmware update images is insufficiently sanitized, allowing post-authentication command injection on the SMM as the root user.
