Affected Products and Versions

11.5.8 - 11.5.9

|

Server

All platforms are affected.
Earlier releases (10.1, 9.7 etc.) may also be affected, but they are no longer supported.

To determine if Federation is enabled, issue the following:

db2 get dbm cfg | grep FEDERATED

If a value of NO is returned, you are not vulnerable.

You can determine if you are using one of the affected wrappers by performing:

To determine if the NoSQL Blockchain wrapper is in use, issue the following statement:

db2 “select * from syscat.serveroptions where option=‘PEER_URL’”

If 1 or more rows are returned, then NoSQL Blockchain wrapper is in use.
