Improper Neutralization of CRLF Sequences in HTTP Headers in Jooby ('HTTP Response Splitting)
Impact
- Cross Site Scripting
- Cache Poisoning
- Page Hijacking
Patches
This was fixed in version 2.2.1.
Workarounds
If you are unable to update, ensure that user supplied data isn't able to flow to HTTP headers. If it does, pre-sanitize for CRLF characters.
References
CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
I've been poking at libraries to see if they are vulnerable to HTTP Response Splitting and Jooby is my third case of finding this vulnerability.
Root Cause
This roots cause back to this line in the Jooby codebase:
The DefaultHttpHeaders takes a parameter validate which, when true (as it is for the no-arg constructor) validates that the header isn't being abused to do HTTP Response Splitting.
Reported By
This vulnerability was reported by @JLLeitschuh (Twitter)
