What an attacker can do

A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. Vendor/CNA’s CVSS 3.1 assessment (base score 6.5/10) rates confidentiality and integrity impact as low; availability impact as none. NVD’s CVSS 3.1 assessment (base score 7.4/10) rates confidentiality and integrity impact as high; availability impact as none.
