[Updated 28 July 2010] The CVE-2010-1871 description has been updated to reflect that an attacker does not need to be authenticated to exploit this issue. No changes have been made to the packages.

The JBoss Seam Framework is an application framework for building web applications in Java.

An input sanitization flaw was found in the way JBoss Seam processed certain parametrized JBoss Expression Language (EL) expressions. A remote attacker could use this flaw to execute arbitrary code via a URL, containing appended, specially crafted expression language parameters, provided to certain applications based on the JBoss Seam framework. Note: A properly configured and enabled Java Security Manager would prevent exploitation of this flaw. (CVE-2010-1871)

Red Hat would like to thank Meder Kydyraliev of the Google Security Team for responsibly reporting this issue.

Users of jboss-seam2 should upgrade to these updated packages, which contain a backported patch to correct this issue. The JBoss server process must be restarted for this update to take effect.
