PM82973: DFHIS1027 SECURITY VIOLATION HAS BEEN DETECTED USING IPCONN

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An ECI request is sent over IPIC with a USERID 7 bytes long.
  USD1 key is 10 bytes long, so CICS paddes the USERID with
  blanks.
  This makes a userid of length 7 with 3 blanks as a userid of
  length 10.
  This allows the length of 10 to work when the user is already
  in the USD1 directory, but to fail when the USERID must be added
  in the security domain.
  When DFHXSSA tries to ADD_USER_WITHOUT_PASSWORD an EXCEPTION is
  issued because USERID_NOT_DEFINED.
  This cause DFHIS1027 - Security violation has been detected
  using IPIC - to be issued .
  DFHUSAD should ignore trailing blanks in the userid.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: MsgDFHIS1027 "Security violation has    *
  *                      been detected using IPCONN" is issued   *
  *                      when using IPCONN and userid is padded  *
  *                      with blanks.                            *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The CICS Transaction Gateway is communicating with CICS using an
  IPCONN connection, and a userid with blank padding is received
  by CICS. If the user is not currently known to CICS then it must
  be added to the user domain. DFHUSAD passes the full length of
  the user id, inclusive of trailing blanks.
  When DFHXSSA tries to ADD_USER_WITHOUT_PASSWORD an EXCEPTION
  is issued because USERID_NOT_DEFINED. Then message DFHIS1027 is
  issued.
  

Problem conclusion

• DFHUSAD has been changed to remove the trailing blanks in the
  userid.
