Seam 2 does not properly block access to EL expressions
-------------------------------------------------------

                 Key: JBSEAM-4844
                 URL: https://issues.jboss.org/browse/JBSEAM-4844
             Project: Seam 2
          Issue Type: Bug
          Components: EL
    Affects Versions: 2.2.2.Final, 2.2.1.Final, 2.2.0.GA
            Reporter: Marek Novotny
            Assignee: Marek Novotny
             Fix For: 2.3.0.ALPHA


Seam 2 does not properly block access to JBoss
Expression Language (EL) constructs in page exception handling, allowing
arbitrary Java methods to be executed. A remote attacker could use this
flaw to execute arbitrary code via a specially-crafted URL provided to
certain applications based on the JBoss Seam 2 framework. Note: A properly
configured and enabled Java Security Manager would prevent exploitation of
this flaw. (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1484)
