IBM i 7.3, 7.4, 7.5, and 7.5 is vulnerable to a host header injection attack caused by improper neutralization of HTTP header content by IBM Navigator for i. An authenticated user can manipulate the host header in HTTP requests to change domain/IP address which may lead to unexpected behavior.
IBM i 7.6
contains a privilege escalation vulnerability due to incorrect profile swapping in an OS command. A malicious actor can use the command to elevate privileges to gain root access to the host operating system.
IBM i 7.4 and 7.5 is vulnerable to a database access denial of service caused by a bypass of a database capabilities restriction check. A privileged bad actor can remove or otherwise impact database infrastructure files resulting in incorrect behavior of software products that rely upon the database.
