CVE-2023-43635, a vulnerability affecting multiple products, involves a key being sealed with SHA1 PCRs instead of the expected SHA256 PCRs. This vulnerability specifically impacts the "vault" directory in the system, which contains sensitive information that needs to be protected. The issue arises when machines have SHA256 PCRs enabled but SHA1 PCRs disabled, which prevents the key from being properly sealed and poses a risk to the security of the organization. To remediate this vulnerability, it is necessary to ensure that the key is sealed using SHA256 PCRs as intended.
