New DCM in SSL still need non-SSL ports

When configuring the new DCM in SSL mode, port 2007 is assigned to the application server and it is possible then to connect using the URL: https://hostname:2007/dcm

BUT, it the background, port 8470 (non-SSL) is still required to complete SIGNON.
For our customer, this port is restricited, as most non-SSL ports, thus preventing DCM to accept SIGNON. We had the same experience when the new Navigator arrived: when configured in SSL it was still requesting the non-ssl Signon port 8470. This had been fixed by developers.

Since the Heritage DCM is now vulnerable, could you please fix the SSL issue with the new DCM ASAP.

All this has been confirmed in CASE TS011384682.

Thank you

    Hello. I reported this anomaly about one year ago now and although we keep our environments current, we have not seen any improvement on the situation.
    This is a security issue and should be treated accordingly.

    Someone suggested some PTFs at the beginning of this thread but they are realted to how to disable the Heritage version. The current problem is with the most recent version od DCM.

    Thank you.

    The CAAC has reviewed this IBM Idea and recommenders that IBM view this as a high priority idea that is important to be addressed.

    New versions for Software should support features that were available in the old version. From a Security perspective, this need to be fixed.

    Background: The COMMON Americas Advisory Council, (CAAC) members have a broad range of experience in working the small ans medium-sized IBM i customers. CAAC has a key role in working with working with IBM i development to help assess the value and impact of individual IBM Ideas of the broader IBM i community and has, therefore reviewed the idea.

    IBM will use this Idea as input to planning, but no commitment is made or implied. This Idea will be updated in the future if IBM implements it.

    I just want to comment that PTFs for heritage DCM were recently released that resolve the vulnerabilities that were identified. The PTF numbers are listed in the published security bulletin.
    Security Bulletin: Digital Certificate Manager for IBM i is vulnerable to cross-site scripting (CVE-2022-34358)
