# IBM Db2 Genius Hub: HTTP response splitting by authenticated remote attacker

IBM Db2 Genius Hub versions 1.1.2 through 1.1.5 do not neutralize HTTP headers properly, which allows HTTP response splitting. A remote attacker with a valid login can inject headers or content into server responses, which can be used to poison caches or trick users' browsers.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Db2 Genius Hub version against the affected range 1.1.2, 1.1.3, 1.1.4, 1.1.5 in the vendor's admin console or installation files
