Subject [jira] [Updated] (OGNL-23) Class.forName() usage is malicious inside OSGi
Date Sat, 22 Oct 2011 01:08:32 GMT

     [ https://issues.apache.org/jira/browse/OGNL-23?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Adrian Cumiskey updated OGNL-23:
--------------------------------

    Attachment: patch-OGNL23.txt

This is a patch file which I believe should satisfy the issue.

All references to Class.forName() have been replaced with calls to OgnlContext.DEFAULT_CLASS_RESOLVER.classForName().
 This method also previously used Class.forName and now it uses ClassLoader.loadClass().

Cheers, Adrian.

> {{Class.forName()}} could make OGNL unusable [inside OSGi|http://olegz.wordpress.com/2008/11/05/osgi-and-classforname/].
> The fix would involve the {{ClassLoader.loadClass()}} method, allowing users setting
a custom {{ClassLoader}
> Classes affected by that issues are:
>  * {{org.apache.commons.ognl.DefaultClassResolver}}
>  * {{org.apache.commons.ognl.OgnlRuntime}}
> The {{org.apache.commons.ognl.ASTMap}} class is affected as well, even if loading {{java.util.LinkedHashMap}}
in that way should be safe.
