Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Bug 1485833

Summary: Missing CN in user signing cert would cause error in cmc user-signed [rhel-7.4.z]

Fixed In Version: pki-core-10.4.1-14.el7_4 Doc Type: Bug Fix
Doc Text:
Previously, an incoming request missing the Common Name (CN) component caused a NullPointerException on the Certificate Authority (CA) because the implementation expected the CN to be present in the subject Distinguished Name (DN) of the CMC. This update allows the CA to handle subject DN without a CN component, preventing the exception from being thrown.

How to reproduce issue:

Environment:
rpm -qa pki-ca
pki-ca-10.4.1-13.el7_4.noarch


Certificate used for testing purpose:

<Certificate snip>
Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number: 525797390 (0x1f57080e)
        Signature Algorithm: PKCS #1 SHA-512 With RSA Encryption
        Issuer: "CN=CA Signing Certificate,OU=rhcs-0day,O=Example-rhcs92-CA"
        Validity:
            Not Before: Wed Sep 27 05:56:15 2017
            Not After : Mon Mar 26 05:56:15 2018
        Subject: "UID=testing,E=Geetikakk"
        Subject Public Key Info:

</Certificate snip>

Testing Steps:

Import certificate in the nssdb with nickname=testing.
Both cmc file and Httpclient file should have:
user-signed/cmc.self.cfg:nickname=testing
user-signed/HttpClient-cmc-crmf.self.cfg:nickname=testing

1. PKCS10Client -d . -p SECret.123 -n "uid=update2"  -o user-signed/pkcs10.req
2. update privatekey value in user-signed/cmc.self.cfg
3. Run CMCRequest user-signed/cmc.self.cfg
4. Run HttpClient user-signed/HttpClient-cmc-crmf.self.cfg
5. CMCResponse -d . -i user-signed/cmc.self.Resp

Testing with Fix:
================

Environment:

rpm -qa pki-ca
pki-ca-10.4.1-15.el7_4.noarch

1. Stop the CA and KRA instance.
2. Upgrade the pki packages
3. Start CA and KRA instance.Perform same test again


Test Case 1: Use the same certificate without CN and make sure certificate is issued.


Perform testing steps as mentioned above.

Comment 4 Geetika Kapoor 2017-09-28 10:42:52 UTC 
I have added test cases mentioned below.Do you think I should be adding more test cases here?

Test Cases:
==========

Test Case 1: Use the same certificate without CN and make sure certificate is issued. 
example: 
Subject: UID=testing,E=Geetikakk

Test Case 2: with muiltple fields in subject dn .

Example : Subject: "UID=testing,E=dmail.smtp@redhat,CN=CHECK,OU=OU3,OU=OU2,OU=O
            U1,OU=OU,O=TEST,C=IN"
