Vulnerability CVE-2019-14823

Vulnerability Name:

CVE-2019-14823 (CCN-169670)

Assigned:

2019-10-14

Published:

2019-10-14

Updated:

2023-02-12

Summary:

A flaw was found in the "Leaf and Chain" OCSP policy implementation in JSS' CryptoManager versions after 4.4.6, 4.5.3, 4.6.0, where it implicitly trusted the root certificate of a certificate chain. Applications using this policy may not properly verify the chain and could be vulnerable to attacks such as Man in the Middle.
