CVE-2023-30630
Description
A vulnerability was found in dmidecode, which allows -dump-bin to overwrite a local file. This issue may lead to the execution of dmidecode via Sudo.
Statement
The impact of the CVE marked as moderate as this CVE relies on an improbable non-default configuration of allowing an unprivileged user to run demidecode under sudo with a specific insecure configuration in the sudoers file. Using dmidecode in such a manner is no different than allowing any other tool to unexpectedly run with elevated privileges.
Mitigation
Do not configure sudoers file to allow running dmidecode with elevated privileges.

Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
