The '''Tatsu Signing Server''' ('''TSS''') is a collection of services provided by Apple. In late 2012, the list of available services was briefly made public at [https://web.archive.org/web/20121128012112/http://gs.apple.com/TSS/ gs.apple.com]. This index page has since been removed, although at least one archived capture exists.

TSS is accessed chiefly for use of the [[SHSH Protocol]] to receive signed blobs for a given iOS build. This is achieved with the SHSH controller at http://gs.apple.com/TSS/controller.

There is an Apple internal equivalent, known as SpiderCab, running at [http://tatsu-tss-internal.apple.com:80 tatsu-tss-internal.apple.com] and [http://tss-int.apple.com:80 tss-int.apple.com], which are only accessible within Apple's VPN. SpiderCab is used to sign internal/debug and test builds of iOS, including old versions that are no longer signed on production.

'''Note: As of 2/18/2020, access to TSS SOAP services is forbidden, likely to all outside of Apple's internal network.''' Reliable communication to the TSS server requires the appropriate HTTP header, as described in [[SHSH Protocol#Communication]]. If you are communicating with a TSS service and not the SHSH controller itself, you must additionally provide a <code>SOAPAction:</code> header containing the URL of the service you are accessing. Also note that '''not all TSS servers accept SOAP requests.'''

The Tatsu Signing Server (TSS) is a collection of services provided by Apple. In late 2012, the list of available services was briefly made public at gs.apple.com. This index page has since been removed, although at least one archived capture exists. TSS is accessed chiefly for use of the SHSH Protocol to receive signed blobs for a given iOS build. This is achieved with the SHSH controller at http://gs.apple.com/TSS/controller.

There is an Apple internal equivalent, known as SpiderCab, running at tatsu-tss-internal.apple.com and tss-int.apple.com, which are only accessible within Apple's VPN. SpiderCab is used to sign internal/debug and test builds of iOS, including old versions that are no longer signed on production.

Note: As of 2/18/2020, access to TSS SOAP services is forbidden, likely to all outside of Apple's internal network. Reliable communication to the TSS server requires the appropriate HTTP header, as described in SHSH Protocol#Communication. If you are communicating with a TSS service and not the SHSH controller itself, you must additionally provide a SOAPAction: header containing the URL of the service you are accessing. Also note that not all TSS servers accept SOAP requests.

Services

There are two services provided, both accessible via SOAP requests. They are located in http://gs.apple.com/TSS/services/ under their respective names. A sample request concerning "getReceiptPacketStatus" from the "tatsuReceiptsStatusPort" service is demonstrated below:

This type of SOAP request/response can be performed with a cURL request, like so (where soap.xml is the location of the aforementioned SOAP XML): 

curl -i -m 1.0 -H "Content-Type: text/xml;charset=utf-8" -A InetURL/1.0 -H "SOAPAction: http://gs.apple.com/TSS/services/tatsuReceiptsStatusPort" -H "Host: gs.apple.com" -d @soap.xml http://gs.apple.com/TSS/services/tatsuReceiptsStatusPort

Note: The server may occasionally return java.lang.NullPointerException despite a valid response. Retrying the request will likely remedy this. Is this a race condition bug on the server side?

PacketPort

pushDataPacket

  • Input Message (pushDataPacketRequest)
  • Output Message (pushDataPacketResponse)

tatsuReceiptsStatusPort

Custom Types

These are custom types defined by the http://receiptsstatus.web.tss.apple.com/ namespace, documented below:

  • status contains a status code and the description for the aforementioned code. The only known status code is 3.
    • code (Integer)
    • desc (String)
  • ReceiptDataPacketStatusRequest
    • code (Number)
  • ReceiptDataPacketStatusResponse
    • [no name] (Long)
    • status (type=status)
    • ip (String)
  • ExpireTSAQueryRequest
    • tsa (Number)
  • ExpireTSAQueryResponse

getReceiptPacketStatus

Returns an unknown number, a status type, and a private IP address (likely meant to be accessed within Apple’s internal VPN).

  • Input Message (getReceiptPacketStatusRequest)
    • param0 (type=ReceiptDataPacketStatusRequest)
  • Output Message (getReceiptPacketStatusResponse)
    • param1 (type=ReceiptDataPacketStatusResponse)

queryTASExpireTSA

  • Input Message (queryTASExpireTSARequest)
    • param2 (type=ExpireTSAQueryRequest)
  • Output Message (queryTASExpireTSAResponse)
    • param3 (type=ExpireTSAQueryResponse)

updateTSSStatus

  • Input Message (updateTSSStatusRequest)
    • param4 (type=status)
  • Output Message (updateTSSStatusResponse)
    • param5 (type=status)

Notes

SoapUI, a test automation framework for the SOAP protocol, lists Apple among their largest users [1].

Server Details

It is of moderate security concern to know that the TSS server runs Apache Tomcat, which is exposed, alongside version number, in the default 404 page. The SOAP implementation used is Apache Axis (Java).
