Discussion

CICS is a transaction-processing product that provides programmers with the facilities to develop interactive applications. Unauthorized access to ACF2/CICS parameter datasets (i.e., product, security) could result in the compromise of the confidentiality, integrity, and availability of the CICS region, applications, and customer data.

Check Content

Refer to the following report produced by the ACF2 Data Collection:

- SENSITVE.RPT(CICSRPT).

Refer to the CICS Systems Programmer Worksheets filled out from previous vulnerability ZCIC0010.
