[原文]The Install Wizard for nCipher MSCAPI CSP 5.50 does not use Operator Card Set protected keys when the user requests them but does not generate the Operator Card Set, which results in a lower protection level than specified by the user (module protection only).

        nCipher MSCAPI CSP 5.50版本的Install Wizard在用户请求但不产生Operator Card Set时不使用受密钥保护的Operator Card Set,该漏洞导致比用户所指定的(只保护模块)更低的保护等级。

- 公告与补丁

        The following fix information has been provided by nCipher:
        1. Users who have NOT already created a key with the wrong protection
        ---------------------------------------------------------------------
        In order to force MSCAPI applications to generate cardset protected keys
        a file `wizardfix.reg' should be created containing the following text:
        ------------ CUT HERE --------------
        Windows Registry Editor Version 5.00
        [HKEY_LOCAL_MACHINE\SOFTWARE\nCipher\Cryptography]
        "UseModuleKeys"=dword:0000000
        ------------ CUT HERE --------------
        This file can then be run by the user to change the appropriate registry
        entry that determines the behavior of key generation using the nCipher
        CSP.
        Alternatively, the user can edit the registry value specified above
        directly using `regedit'.
        The registry setting must be reset using either of the above methods
        after each invocation of the affected nCipher CSP Install Wizard.
        2. Users who have already created a key which is erroneously module
         protected
        -------------------------------------------------------------------
        Users who have already generated keys which were intended to be cardset
        protected, but due to this error are not, are advised to apply the above
        registry fix and generate new keys. nCipher recommends against
        converting existing module-protected keys to cardset-protected status,
        since it is extremely difficult to do this in a way that increases
        security.
        nCipher customers are advised to contact nCipher at support@ncipher.com for information on receiving patches and updates which address this issue.

- 漏洞讨论

nCipher produces a range of hardware and software security products. An issue has been reported in version 5.50 of the install wizard for the MSCAPI CSP key generator under Windows 2000.

Under some circumstances, a key generated that should be protected by an Operator card will in fact be generated as only module protected. This may result in weaker security than anticipated, and under some deployments reduce or break the security model.

** It has been reported that a similar issue exists in the command line utility 'domesticinstall.exe' included with versions 5.50 and 5.54.

- 漏洞利用

No exploit is required.

- 解决方案

The following fix information has been provided by nCipher:

1. Users who have NOT already created a key with the wrong protection
---------------------------------------------------------------------

In order to force MSCAPI applications to generate cardset protected keys
a file `wizardfix.reg' should be created containing the following text:

------------ CUT HERE --------------
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\nCipher\Cryptography]
"UseModuleKeys"=dword:0000000
------------ CUT HERE --------------

This file can then be run by the user to change the appropriate registry
entry that determines the behavior of key generation using the nCipher
CSP.

Alternatively, the user can edit the registry value specified above
directly using `regedit'.

The registry setting must be reset using either of the above methods
after each invocation of the affected nCipher CSP Install Wizard.

2. Users who have already created a key which is erroneously module
protected
-------------------------------------------------------------------

Users who have already generated keys which were intended to be cardset
protected, but due to this error are not, are advised to apply the above
registry fix and generate new keys. nCipher recommends against
converting existing module-protected keys to cardset-protected status,
since it is extremely difficult to do this in a way that increases
security.

nCipher customers are advised to contact nCipher at support@ncipher.com for information on receiving patches and updates which address this issue.
