Detailsinfo

A vulnerability was found in Lenovo System X and IBM System X (the affected version is unknown) and classified as critical. Affected by this issue is an unknown code of the component SFTP Handler. The manipulation with an unknown input leads to a hard-coded credentials vulnerability. Using CWE to declare the problem leads to CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The bug was discovered 07/26/2018. The weakness was disclosed 07/26/2018 (Website). The advisory is shared for download at support.lenovo.com.
