CVE-2018-9068
https://notcve.org/view.php?id=CVE-2018-9068
The IMM2 First Failure Data Capture function collects management module logs and diagnostic information when a hardware error is detected. This information is made available for download through an SFTP server hosted on the IMM2 management network interface. In versions earlier than 4.90 for Lenovo System x and earlier than 6.80 for IBM System x, the credentials to access the SFTP server are hard-coded and described in the IMM2 documentation, allowing an attacker with management network access to obtain the collected FFDC data. After applying the update, the IMM2 will create random SFTP credentials for use with OneCLI. La función IMM2 First Failure Data Capture recopila información de diagnóstico y registros de los módulos de gestión cuando se detecta un error de hardware. • https://support.lenovo.com/us/en/solutions/LEN-20227 • CWE-798: Use of Hard-coded Credentials •
CVE-2017-3775
https://notcve.org/view.php?id=CVE-2017-3775
Some Lenovo System x server BIOS/UEFI versions, when Secure Boot mode is enabled by a system administrator, do not properly authenticate signed code before booting it. As a result, an attacker with physical access to the system could boot unsigned code. Algunas versiones BIOS/UEFI del servidor x de Lenovo, cuando Secure Boot está habilitado por un administrador del sistema, no autentican correctamente el código firmado antes de cargarlo. Como resultado, un atacante con acceso físico al sistema podría cargar código no firmado. • https://support.lenovo.com/us/en/solutions/LEN-20241 • CWE-287: Improper Authentication •
CVE-2017-3774
https://notcve.org/view.php?id=CVE-2017-3774
A stack overflow vulnerability was discovered within the web administration service in Integrated Management Module 2 (IMM2) earlier than version 4.70 used in some Lenovo servers and earlier than version 6.60 used in some IBM servers. An attacker providing a crafted user ID and password combination can cause a portion of the authentication routine to overflow its stack, resulting in stack corruption. Se ha descubierto una vulnerabilidad de desbordamiento de pila en el servicio de administración web en Integrated Management Module 2 (IMM2), en versiones anteriores a la 4.70 empleadas en algunos servidores de Lenovo y en versiones anteriores a la 6.60 empleadas en algunos servidores de IBM. Un atacante que proporcione una combinación de ID y contraseña manipulados puede hacer que una porción de la rutina de autenticación desborde su pila, lo que provoca una corrupción de la pila. • https://support.lenovo.com/us/en/product_security/LEN-19586 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-3744
https://notcve.org/view.php?id=CVE-2017-3744
In the IMM2 firmware of Lenovo System x servers, remote commands issued by LXCA or other utilities may be captured in the First Failure Data Capture (FFDC) service log if the service log is generated when that remote command is running. Captured command data may contain clear text login information. Authorized users that can capture and export FFDC service log data may have access to these remote commands. En el firmware IMM2 de los servidores Lenovo System x, los comandos remotos enviados por LXCA u otras utilidades pueden ser capturados en el registro del servicio First Failure Data Capture (FFDC) si el registro del servicio se genera cuando ese comando remoto está en ejecución. Los datos de comando capturados podrían contener información de inicio de sesión en texto claro. • https://support.lenovo.com/product_security/LEN-14054 • CWE-532: Insertion of Sensitive Information into Log File •
