Subject [jira] [Commented] (CASSANDRA-12324) Use of Dynamic Class Loading, Use of Externally-Controlled Input to Select Classes or Code
Date Wed, 27 Jul 2016 16:14:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15395916#comment-15395916

Jeremiah Jordan commented on CASSANDRA-12324:
---------------------------------------------

[~EdAInWestOC] "reproduced in" is the correct place to put 3.0.5 is the "fix version" field
is the version that we fixed the issue in, not the version it was found in.

>             Project: Cassandra
>          Issue Type: Bug
>            Reporter: Eduardo Aguinaga
>             Fix For: 3.0.5

> Overview:
> In May through June of 2016 a static analysis was performed on version 3.0.5 of the Cassandra
source code. The analysis included an automated analysis using HP Fortify v4.21 SCA and a
manual analysis utilizing SciTools Understand v4. The results of that analysis includes the
issue below.
> Issue:
> Dynamically loaded code has the potential to be malicious. The application uses external
input to select which classes or code to use, but it does not sufficiently prevent the input
from selecting improper classes or code.
> The snippet below shows the issue which ends on line 436 by returning an object associated
with a class by name.
> {code:java}
> FBUtilities.java, lines 432-442:
> 432 public static <T> Class<T> classForName(String classname, String readable)
throws ConfigurationException
> 433 {
> 434     try
> 435     {
> 436         return (Class<T>)Class.forName(classname);
> 437     }
> 438     catch (ClassNotFoundException | NoClassDefFoundError e)
> 439     {
> 440         throw new ConfigurationException(String.format("Unable to find %s class '%s'",
readable, classname), e);
> 441     }
> 442 }
> {code}
