- Summary
- Zoraxy 3.2.3 through 3.3.4 Client IP Spoofing via X-Forwarded-For IPv6
- Details
-
Zoraxy versions 3.2.3 through 3.3.4 fail to properly parse IPv6 addresses in the RemoteAddr field when setting forwarded headers. Unauthenticated attackers connecting over IPv6 can supply arbitrary X-Forwarded-For values to spoof their source IP and bypass authorization provider IP-based access controls.
