Technical ContextAI · show details

This vulnerability is classified as Use of Hard-coded Credentials (CWE-798), which allows attackers to gain access using credentials embedded in source code. 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. Affected products include: Lenovo Flex System X240 M4 Firmware, Lenovo Flex System X240 M5 Firmware, Lenovo Flex System X280 X6 Firmware, Lenovo Flex System X440 M4 Firmware, Lenovo Flex System X480 X6 Firmware.
