| <p>The Apache Tomcat<sup>®</sup> Security Team rates the impact of each security flaw |
| that affects Tomcat. We've chosen a rating scale quite similar to those |
| used by other major vendors in order to be consistent. Basically the goal |
| of the rating system is to answer the question "How worried should I be |
| about this vulnerability?".</p> |
| |
| <p>Note that the rating chosen for each flaw is the worst possible case |
| across all architectures. To determine the exact impact of a particular |
| vulnerability on your own systems you will still need to read the security |
| advisories to find out more about the flaw.</p> |
| |
| <p>We use the following descriptions to decide on the impact rating to give |
| each vulnerability:</p> |
| |
| </div><h3 id="Critical">Critical</h3><div class="text"> |
| <p>A vulnerability rated with a Critical impact is one which could |
| potentially be exploited by a remote attacker to get Tomcat to execute |
| arbitrary code (either as the user the server is running as, or root). |
| These are the sorts of vulnerabilities that could be exploited |
| automatically by worms.</p> |
| </div><h3 id="Important_/_High">Important / High</h3><div class="text"> |
| <p>A vulnerability rated as Important (or High) impact is one which could |
| result in the compromise of data or availability of the server. For |
| Tomcat this includes issues that allow an easy remote denial of service |
| (something that is out of proportion to the attack or with a lasting |
| consequence), access to arbitrary files outside of the context root, or |
| access to files that should be otherwise prevented by limits or |
| authentication.</p> |
| </div><h3 id="Moderate">Moderate</h3><div class="text"> |
| <p>A vulnerability is likely to be rated as Moderate if there is significant |
| mitigation to make the issue less of an impact. This might be because the |
| flaw does not affect likely configurations, or it is a configuration that |
| isn't widely used, or where a remote user must be authenticated in order |
| to exploit the issue. Flaws that allow Tomcat to serve directory listings |
| instead of index files and cross-site scripting issues are included here. |
| </p> |
| </div><h3 id="Low">Low</h3><div class="text"> |
| <p>All other security flaws are classed as a Low impact. This rating is used |
| for issues that are believed to be extremely hard to exploit, or where an |
| exploit gives minimal consequences.</p> |
