CVE-2023-30630
7.1 · HIGHOverview
CVE-2023-30630 is a high-severity vulnerability affecting nongnu dmidecode. It was published on April 13, 2023 and has a CVSS 3.1 base score of 7.1 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
Dmidecode before 3.5 allows -dump-bin to overwrite a local file. This has security relevance because, for example, execution of Dmidecode via Sudo is plausible. NOTE: Some third parties have indicated the fix in 3.5 does not adequately address the vulnerability. The argument is that the proposed patch prevents dmidecode from writing to an existing file. However, there are multiple attack vectors that would not require overwriting an existing file that would provide the same level of unauthorized privilege escalation (e.g. creating a new file in /etc/cron.hourly).
Remediation
Check the references section for vendor advisories and patches from nongnu. Update dmidecode to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
