+
+ <p>If:</p>
+ <ul>
+ <li>an attacker is able to control the contents and name of a file on the
+ server; and</li>
+ <li>the server is configured to use the <code>PersistenceManager</code>
+ with a <code>FileStore</code>; and</li>
+ <li>the <code>PersistenceManager</code> is configured with
+ <code>sessionAttributeValueClassNameFilter="null"</code> (the default
+ unless a <code>SecurityManager</code> is used) or a sufficiently lax
+ filter to allow the attacker provided object to be deserialized;
+ and</li>
+ <li>the attacker knows the relative file path from the storage location
+ used by <code>FileStore</code> to the file the attacker has control
+ over;</li>
+ </ul>
+ <p>then, using a specifically crafted request, the attacker will be able to
+ trigger remote code execution via deserialization of the file under
their
+ control.</p>
+
+ <p><strong>Note:</strong> All of conditions above must be true for the
+ attack to succeed.</p>
+
+ <p>As an alternative to upgrading to 10.0.0-M5 or later, users may
configure
+ the <code>PersistenceManager</code> with an appropriate value for
+ <code>sessionAttributeValueClassNameFilter</code> to ensure that only
+ application provided attributes are serialized and deserialized.</p>
+
+ <p>This was fixed with commit

+ <p>This issue was reported to the Apache Tomcat Security Team by by jarvis
