CVE-2023-43630 is a vulnerability that affects multiple products, including those identified as 'syj3oM', 'syj3oN', 'syj3oO', 'syj3oP', 'syj3oU', 'syj3oV', 'syj3oW', 'syj3oX', 'syj3oQ', 'syj3oR', 'syj3oS', 'syj3oT', and 'syj3oY'. The vulnerability allows an attacker to modify the config partition without triggering the measured boot process. This issue is caused by the use of SHA1 PCRs instead of SHA256 for sealing/unsealing the "vault" key, as well as a specific code implementation in "measurefs.go" that only updates the SHA256 instance of PCR14. Fixing this issue alone would not solve the problem of incorrect measurement. The potential danger posed by this vulnerability is high, with a base severity rating of HIGH according to NIST's National Vulnerability Database (NVD). Organizations should apply necessary patches or updates to remediate this vulnerability and prevent unauthorized modifications to the config partition.
