A set of six high-severity firmware vulnerabilities impacting a broad range of HP Enterprise devices are still waiting to be patched, although some of them were publicly disclosed since July 2021.
Firmware flaws are particularly dangerous because they can lead to malware infections that persist even between OS re-installations or allow long-term compromises that would not trigger standard security tools.
As Binarly highlights in the report, even though it’s been a month since they made some of the flaws public at Black Hat 2022, the vendor hasn’t released security updates for all impacted models, leaving many customers exposed to attacks.
HP has released three security advisories acknowledging the mentioned vulnerabilities, along with an equal number of BIOS updates addressing the issues for some of the impacted models.
CVE-2022-23930 was fixed on all impacted systems in March 2022, except for thin client PCs .
CVE-2022-31644, CVE-2022-31645, and CVE-2022-31646 received security updates on August 9, 2022.

As Binarly comments, fixing firmware flaws is very challenging for a single vendor due to the complexity of the firmware supply chain, so many HP customers will have to accept the risk and ramp up their physical security measures.
