CVSS v3.1

7.4

High

VectorAV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N
Name of the Vulnerable Software and Affected Versions JSS' CryptoManager versions after 4.4.6, 4.5.3, 4.6.0
Description A flaw was found in the "Leaf and Chain" OCSP policy implementation 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.
Recommendations For JSS' CryptoManager versions after 4.4.6, 4.5.3, 4.6.0, consider disabling the "Leaf and Chain" OCSP policy until a patch is available to prevent implicit trust of the root certificate. Restrict access to applications using this policy to minimize the risk of exploitation. Avoid using the affected CryptoManager versions in sensitive environments until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
