Re: how to block bad request?

[Jason Wee]

Hi Mark,

Thank you. I enabled debugging and able to reproduce (close to
matching, but not exact same output)

send null byte

The different is

%b - Bytes sent, excluding HTTP headers, or '-' if zero
%D - Time taken to process the request in microseconds


so I guess the attacker check if the port is opened without sending
any bytes and tomcat took 0 second to process.


Christopher,

no, X-Forwarded-For and %h values are not the same.

how to block bad request?

[Jason Wee]

Hi,

Happy new year everyone.

Background of my production setup. Using tomcat 10 and in linux
environment, using the following accesslog valve

%a %{X-Forwarded-For}i %h %l %u %t '%r' %s %b '%{Referer}i'
'%{User-Agent}i' %D %S

I often see the above registered in accesslog and have the following questions

1. how/where to find more information about such requests? example how
to reproduce of such request, how to enable debug to give more details
about such request, etc?
2. how to block such requests (at tomcat or at firewall or any other way)?
3. what impact it has to tomcat (or service) if these requests come in
huge amounts and in a short time.

Thank you and happy to hear any other comments/opinions too.

Kind regards,
Jason

Re: Question about upgrade from Tomcat 7 to Tomcat 9.0.67

[Jason Wee]

i would normally do a diff between your current version and the next
tomcat version you want to upgrade to and go through the diff slowly.
it is better to be careful and note the changes than sorry later.

Re: Regarding IPv6 support

check if tomcat is listening on ipv6, using ss or netstat command.
need more details about your environment, how requests are pass to
container, etc...

Re: Compile JSP pages dynamically using Tomcat 6.0.45

[Jason Wee]

yes, i think so, it is ecj that did the compilation not the jre/jdk...

max version u can go with tomcat6 is java8, see

} else if(opt.equals("1.7")) {
settings.put(CompilerOptions.OPTION_Source,
 CompilerOptions.VERSION_1_7);
} else if(opt.equals("1.8")) {
settings.put(CompilerOptions.OPTION_Source,
 "1.8"); // CompilerOptions.VERSION_1_8
} else {
log.warn("Unknown source VM " + opt + " ignored.");
settings.put(CompilerOptions.OPTION_Source,
CompilerOptions.VERSION_1_5);
}

i suggest you really consider upgrade tomcat.

my path was tomcat6 - > tomcat8 -> tomcat10

Re: Compile JSP pages dynamically using Tomcat 6.0.45

[Jason Wee]

yes, i used to use tomcat version 6.0.29 then upgraded to 6.0.53
eventually jsp cannot compile to java 8 spec, so i have to upgrade ecj
to version 4.6.1 and using jdk8u74. But these were all I can recalled.

Re: Upgrade tomcat 7 to 10.

[Jason Wee]

As what Christopher Schultz mentioned, "including switching package
names", i.e. from javax to jakarta.. when I did the webapp migration
to tomcat 10, I had to make all the libraries to reference jakarta
though, including taglib-mailer, jsp  and so on.

Re: java.lang.ClassNotFoundException: javax.servlet.Filter

[Jason Wee]

No problem, just wanna understand better if this will tackle in the near future.

On another note, I did custom patch on one of the lib,
https://github.com/jasonwee/jakarta-taglibs-mailer for my own usage.

I guess I will do the same for this lib if I found time. If you want a
custom or specific patch, please also let me know so I can contribute
back to the tomcat community.

Thank.

Jason

Re: java.lang.ClassNotFoundException: javax.servlet.Filter

[Jason Wee]

okay, currently there is no custom application code, I just build two
of the libs and place into tomcat lib using the tomcat documentation.

Do you mean I have to change the reference? Example
https://github.com/apache/openwebbeans/blob/master/webbeans-web/src/main/java/org/apache/webbeans/servlet/WebBeansConfigurationListener.java#L36
?

Using Apache Tomcat 10.0.2, build owb and cxf and placed into lib directory

tomcat-cxf-3.4.1.jar

owb and cxf module should include in the release source package

[Jason Wee]

Reading https://tomcat.apache.org/tomcat-10.0-doc/cdi.html ,

```
cd $TOMCAT_SRC/modules/owb
mvn clean && mvn package
```

this is not included in the release source package but can only be
found https://github.com/apache/tomcat/tree/master/modules , is this
intentional or the documentation need to specify that to reference owb
and cxf module at github instead?

Re: tomcat http error code 502

[Jason Wee]

Thanks Chris, I took a look at tomcat codebase, I cannot pinpoint too
where is the code that actually logs error 502 to accesslog too.

thanks, this is helpful, I have checked my codebase, the 502 that
client receives would probably be at client proxy.

when you stack them, do you mean you cat those certificates into one pem file?

Re: Unable to start tomcat

[Jason Wee]

This looks informative and should give u hint and where you should
begin troubleshooting.

org.apache.tomcat.jni.Error: 730055: An operation on a socket could not
be performed because the system lacked sufficient buffer space or because
a queue was full.

org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun

[Jason Wee]

Hi,

we are using tomcat version 8.5.20 and we encounter the following exceptions

24-Jul-2019 23:24:45.398 SEVERE [https-jsse-nio-8443-exec-104]

and it happened a lot of times in a day everyday. However, when
upgrade tomcat to version 8.5.43 (current latest), the exception no
longer happened.

We would like to understand better which patch that fix the problem
above. Can anyone give links to the fixes?

Thank you and apache tomcat is a great product!

Jason

Re: Does Tomcat server printout System.out.print infor?

[Jason Wee]

default tomcat , when you print, logging should goes to catalina.out.
In any case, check logging.properties in tomcat directory on where the
logging configured.

as for realm, it can be configure in the context element, which mean
in the META-INF/context.xml, see
https://tomcat.apache.org/tomcat-8.0-doc/realm-howto.html#Configuring_a_Realm
