Getting "java.lang.StringIndexOutOfBoundsException: String index out of range: -1" from malformed requests

Ali Jan 27, 2014

My workplace is doing penetration testing on our Confluence site and the Confluence logs are filling up with these:

--------------------------
Parameters
--------------------------
caused by: java.lang.StringIndexOutOfBoundsException: String index out of range: -1
at java.lang.String.substring(String.java:1937)

2014-01-27 17:26:47,882 ERROR [http-8080-58] [[Catalina].[localhost].[/confluence].[file-server]] log Servlet.service() for servlet file-server threw exception

        at com.atlassian.plugin.webresource.SingleDownloadableResourceBuilder.parse(SingleDownloadableResourceBuilder.java:51)

The only way I've found to recover from this is to "kill -9" the tomcat process, and restart the whole thing.

Is there a way to prevent these kinds of malformed URLs from apparently knocking over the server? We haven't yet gotten the full report from the penetration testing, but it sounds like it's going to be a doozy. :-)

Hmmm that,s odd, maybe is some old data stuck in Confluence index, did you tried to

I didn't get a chance to try that out, but I'll keep it in mind for next time.

This occurs due to the extra slash in the end of the URL:

http://confluence.example.com:80/confluence/

It should be http://confluence.example.com:80/confluence instead.

KB created for this in JIRA:  https://jira.atlassian.com/browse/JRA-44887

Cheers,
Andre
