Midnight Coders Information for VU#307983

Action Message Format (AMF3) Java implementations are vulnerable to insecure deserialization and XML external entities references


Unknown. If you are the vendor named above, please contact us to update your status.

Vendor Statement

The demonstrated code would not be able to be able to cause any harm for the reason that calling setAutoCommit( true ) requires a connection object which is not even initialized at that time (see lines 4067-4087 at: http://www.docjar.com/html/api/com/sun/rowset/JdbcRowSetImpl.java.html).

Additionally, in our implementation all com.sun.* and java.* classes are excluded from deserialization.
