IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 (ACS) is vulnerable to downloading unverified product code when configured to update from an IBM i. A bad actor could use this vulnerablity to run compromised code on the ACS user's workstation.
The issues can be fixed by upgrading to version 1.1.9.14 or later.
