CVE-2022-41915
MEDIUM6.5EPSS 0.50%Netty vulnerable to HTTP Response splitting from assigning header value iterator
Published: 12/12/2022Modified: 4/28/2026
Also known as:DEBIAN-CVE-2022-41915
Description
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.
