Hoss Man reopened SOLR-2631:
----------------------------
we shouldn't consider tis resolved until we also apply the "work around"
provided by Edoardo to the example and test solrconfig.xml files as well.
that way people who copy them in the future won't get any error at all.
> PingRequestHandler can infinite loop if called with a qt that points to
> itsself

> Key: SOLR-2631
> URL: https://issues.apache.org/jira/browse/SOLR-2631
> Project: Solr
> Issue Type: Bug
> Components: search, web gui
> Affects Versions: 1.4, 3.1, 3.2, 3.3
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Labels: security
> Fix For: 3.4, 4.0
>
> Attachments: SOLR-2631.patch
>
>
> We got a security report to priv...@lucene.apache.org, that Solr can infinite
> loop, use 100% CPU and stack overflow, if you execute the following HTTP
> request:
> - http://localhost:8983/solr/select?qt=/admin/ping
> - http://localhost:8983/solr/admin/ping?qt=/admin/ping
> The qt paramter instructs PingRequestHandler to call the given request
> handler. This leads to an infinite loop. This is not an security issue, but
> for an unprotected Solr server with unprotected /solr/select path this makes
> it stop working.
> The fix is to prevent infinite loop by disallowing calling itsself.
