CVE-2022-41915
December 13, 2022
Netty project is an event-driven asynchronous network application framework. Starting in version 4.1.83.Final and prior to 4.1.86.Final, when calling "DefaultHttpHeadesr.set" with an iterator of values, header value validation was not performed, allowing malicious header values in the iterator to perform HTTP Response Splitting. This issue has been patched in version 4.1.86.Final. Integrators can work around the issue by changing the "DefaultHttpHeaders.set(CharSequence, Iterator<?>)" call, into a "remove()" call, and call "add()" in a loop over the iterator of values.
