Description
After upgrading to Spring Boot 2.5.8 which is shipped with Undertow 2.2.14.Final, we have noticed some requests are getting 500 response and on further investigation we found the following exception when the first address in X-Forwarded-For has as ipv6 with leading 0 in any part of it.
03:40:26.122 DEBUG [ XNIO-1 I/O-4] io.undertow.request.error-response : Setting error code 500 for exchange HttpServerExchange{ GET /xyz} java.lang.RuntimeException: null at io.undertow.server.HttpServerExchange.setStatusCode(HttpServerExchange.java:1484) at io.undertow.server.Connectors.executeRootHandler(Connectors.java:420) at io.undertow.server.protocol.http.HttpReadListener.handleEventWithNoRunningRequest(HttpReadListener.java:256) at io.undertow.server.protocol.http.HttpReadListener.handleEvent(HttpReadListener.java:136) at io.undertow.server.protocol.http.HttpOpenListener.handleEvent(HttpOpenListener.java:162) at io.undertow.server.protocol.http.HttpOpenListener.handleEvent(HttpOpenListener.java:100) at io.undertow.server.protocol.http.HttpOpenListener.handleEvent(HttpOpenListener.java:57) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:291) at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:286) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.nio.QueuedNioTcpServer2.acceptTask(QueuedNioTcpServer2.java:178) at org.xnio.nio.WorkerThread.safeRun(WorkerThread.java:612) at org.xnio.nio.WorkerThread.run(WorkerThread.java:479) 03:40:26.122 DEBUG [ XNIO-1 I/O-4] io.undertow.request.io : UT005013: An IOException occurred java.io.IOException: UT000185: Invalid IP address 2001:0DB8:5ecc:f5eb:0ee8:34a2:360a:8f65 at io.undertow.util.NetworkUtils.parseIpv6AddressToBytes(NetworkUtils.java:121) at io.undertow.util.NetworkUtils.parseIpv6Address(NetworkUtils.java:90) at io.undertow.server.handlers.ProxyPeerAddressHandler.handleRequest(ProxyPeerAddressHandler.java:76) at io.undertow.server.handlers.GracefulShutdownHandler.handleRequest(GracefulShutdownHandler.java:94) at io.undertow.server.Connectors.executeRootHandler(Connectors.java:387) at io.undertow.server.protocol.http.HttpReadListener.handleEventWithNoRunningRequest(HttpReadListener.java:256) at io.undertow.server.protocol.http.HttpReadListener.handleEvent(HttpReadListener.java:136) at io.undertow.server.protocol.http.HttpOpenListener.handleEvent(HttpOpenListener.java:162) at io.undertow.server.protocol.http.HttpOpenListener.handleEvent(HttpOpenListener.java:100) at io.undertow.server.protocol.http.HttpOpenListener.handleEvent(HttpOpenListener.java:57) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:291) at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:286) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.nio.QueuedNioTcpServer2.acceptTask(QueuedNioTcpServer2.java:178) at org.xnio.nio.WorkerThread.safeRun(WorkerThread.java:612) at org.xnio.nio.WorkerThread.run(WorkerThread.java:479)
Expected Behaviour:
The request should be processed. ProxyPeerAddressHandler should set the address as unresolved.
Actual Behaviour:
The request is dropped with 500 response code and exception trace as mentioned above. This issue also exists in versions earlier to 2.2.14.Final if there is only one address in X-Forwarded-For and it has ipv6 format with leading 0 in any part.
