SV-7193r1_rule CICS regions are improperly protected to prevent unauthorized propagation of the region userid.

Vulnerability discussion

CICS is a transaction-processing product that provides programmers with the facilities to develop interactive applications. Improperly defined or controlled CICS userids (i.e., region, default, and terminal users) may provide an exposure and vulnerability within the CICS environment. This could result in the compromise of the confidentiality, integrity, and availability of the CICS region, applications, and customer data.

Check content

a) Refer to the following report produced by the RACF Data Collection: - SENSITVE.RPT(PROPCNTL) Refer to the CICS Systems Programmer Worksheets filled out from previous vulnerability ZCIC0010. b) Ensure the CICS region is defined to the PROPCNTL resource class. c) If (b) are true, there is NO FINDING. d) If (b) is untrue, this is a FINDING.

Fix text

Utilize propagation control for each CICS region. Under no circumstance should a user's batch job submitted from a CICS region execute under that CICS region's userid. To prevent this from occurring, define a profile in the PROPCNTL resource class for each CICS region. The following is an example: RDEFINE PROPCNTL OWNER(ADMIN) AUDIT(ALL(READ)) The PROPCNTL class must be active and RACLISTed for this protection to be in effect: SETROPTS CLASSACT(PROPCNTL) RACLIST(PROPCNTL)

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
