XR Taskgroup permission for Cisco Prime: XML Get -> AdminOperational -> PlatformInventory

BRIAN SEKLECKI
Level 1
Level 1

All:

  Is there an equivalent command to "describe" that allows enumeration of required taskgroup requirements, but for the XML API?

  The CLI Command "admin show inventory" seems (to me, to be) analogous to the following XML query:

   <?xml version="1.0" encoding="UTF-8"?>
 <Request>
  <Get xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <AdminOperational>
    <PlatformInventory>
     <RackTable>
      <Rack>  
       <Naming><Name Match="*"/ <.....>

If I run this XML query as the default XR users from group root-system, the query returns fine.

When I run it with a "Meta" user (setup for use by Cisco Prime) which has been given an XR tasklist, which for troubleshooting purposes, should seem to have every possible permission -- per the output below, I get an error:

   "A user is attempting to carry out an unauthorized operation..."

IOS-XR-4.3.4 # show run formal taskgroup | include admin
Thu Feb 11 23:40:53.111 UTC
taskgroup prime task read admin
taskgroup prime task write admin
taskgroup prime task execute admin

I get the following error:


<?xml version="1.0" encoding="UTF-8"?>
<Response MajorVersion="1" MinorVersion="0">
    <Get ErrorCode="0x43679000" ErrorMsg="&apos;XML Service Library&apos; detected the &apos;warning&apos; condition &apos;An error was encountered in the XML beneath this operation tag&apos;" ItemNotFound="true">
        <AdminOperational>
            <PlatformInventory MajorVersion="0" MinorVersion="4">
                <RackTable>
                    <Rack>
                        <Naming>
                            <Name Match="*"/>
                        </Naming>
                        <Attributes ErrorCode="0x43689800" ErrorMsg="&apos;XMLMDA&apos; detected the &apos;warning&apos; condition &apos;A user is attempting to carry out an unauthorized operation&apos;"/>
                    </Rack>
                </RackTable>
            </PlatformInventory>
        </AdminOperational>
    </Get>
    <ResultSummary ErrorCount="1"/>
</Response>

that is interesting, didnt expect that from the permission details of the command itself.

I noticed that in your task list the task read inventory was not there (shouldn't be needed considering you have read sysmgr), but worth the final shot to see if that can carry out the command.

also verify if the cli command can be executed (this to separate it from beign an xml permission issue).

based on that you may want to request a DDTS for this, because this inventory command should not need this high permission level of root system, albeit you have a workaround now.

hi!

ah I see, the permission level needed for this command is not set correctly on the user.

you'd want to add read for sysmgr OR inventory added to the permission levels for the user prime.

root-system provides that task set hence succeeds from cli.

You'll likely see an error too when you log in with user prime and run this command.

cheers!

Nah the problem still happens eve if you grant the Prime tasklist every task every permission:

bash$ TGNAME=prime; for task in $(awk '{print $1}' < list_of_ios-xr_tasks.txt); do for perm in read write execute debug; do echo taskgroup $TGNAME task $perm $task; done ; done;                                                                                                taskgroup prime task read aaa

I've been trying to figure out how to get the proper taskid requirements for certain XML calls. This debug is gold. Thank you!

Just to clarify: There is no work-around except to give Prime root-system or to "inherit root-system"

Both are unacceptable to any BOFH/INFOSEC group by and standard in any organization.

I do slightly have to admonish the Cisco IOS-XR and Prime Networking teams for not having found this bug in advance and/or published a document on best-practices for Prime meta-user security.

(Cisco can make it up to me by not taking 22 months to release a SMU to fix this!) >:}

~BAS

I agree with you on all points. And as mentioned a simple command like this should not require such high permission settings.

Hence wanted to recommend to have a DDTS filed for this, and yes when it is resolved we can definitely do a SMU for this on 533.

Could I ask if you can request the TAC engineer to file a ddts and get in touch with me so we can manage this through adequately in 21 months (see improving ;). Nah of course as fast as possible.

this is not a tricky thing and rather simple to take care of.

Alexander:

  Thanks for being a Rock Star on this!

   We will submit the DDTS today; actually, what we're going to do is have our Cisco Prime SE team submit the request on our behalf, which, based on the fact that it comes internally vs externally, will hopefully help the process along even more.

Your friends in PA/Virginia

  ~BAS

PS: I've got a 4+-bottle case of Copper Fox whiskey and Boyd & Blair vodka for the Cisco engineer who first publishes a signed SMU for us to test.

Hey Bas! found the issue. XML and CLI use different (permission) settings and the admin oper inventory reports root-system as its requirement!

Considering that very cool offer, I could not resist and pass on a test smu for you to play with on 5.3.3 :) This is what is called an engineering smu and is officially not supported, but for a lab test to proof the concept this is fine.

When you have a DDTS filed for this let me know the number so I can attach my diffs to it etc. Or have your SE contact me so I can help him close that off from his end.

cheers from your fan in MA! :)

xander

ps I didnt test/verify this myself, also I built the smu with the pre-computed restart type, it may be a process restart, but it possibly should be a reload because of the API change I had to make. But try it out, if it doesnt reload, and doesn't function give the chassis a reboot (assuming lab here :).

ps2 after download change filename to a .pie instead of that docx. md5 and file info is in the txt along with signature as requested!

Thanks for the test Bas. Ok let me look into this a bit more. I am researching if I probably need to rebuild the schema's before compiling the smu.

I'll be back in touch when I have some update smu for testing.

I got a note from the TAC engineer you're working with and he was going to file a ddts for this also. a fix in a new sw release will for sure take care of this with the fix I have here since it rebuilds the schemas as we want.

a smu on an existing release may need some trick work, apparently.
