Description

JBoss Seam 2 (jboss-seam2), as used in JBoss Enterprise Application Platform 4.3.0 for Red Hat Linux, does not properly sanitize inputs for JBoss Expression Language (EL) expressions, which allows remote attackers to execute arbitrary code via a crafted URL. NOTE: this is only a vulnerability when the Java Security Manager is not properly configured.

• CWE-917Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection')The product constructs all or part of an expression language (EL) statement in a framework such as a Java Server Page (JSP) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended EL statement before it is executed.
