Summary
Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') in Armeria
Details

Versions of Armeria 0.85.0 through and including 0.96.0 are vulnerable to HTTP response splitting, which allows remote attackers to inject arbitrary HTTP headers via CRLF sequences when unsanitized data is used to populate the headers of an HTTP response.

Impact

  1. Cross-User Defacement
  2. Cache Poisoning
  3. Cross-Site Scripting (XSS)
  4. Page Hijacking

Root Cause

The root cause is due to the usage of Netty without the HTTP header validation.

Patches

This vulnerability has been patched in 0.97.0.
