CVE-2023-37920

30
FAUCET Score

CVE-2023-37920 is a critical vulnerability affecting Certifi versions prior to 2023.07.22, as well as products like fedoraproject and netapp that rely on Certifi's root certificate store. The vulnerability stems from Certifi's inclusion of "e-Tugra" root certificates, which were found to have security issues. With a CVSS score of 9.8 (CRITICAL), this vulnerability allows for unauthenticated remote attacks with low complexity, potentially leading to complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code, or significant community discussion beyond a single mention related to a Juniper Networks patch.
