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. This modules also has been tested successfully against IBM
|
|
WebSphere 6.1 running on iSeries.
|
|
|
|
NOTE: this is only a vulnerability when the Java Security Manager is not properly
|
|
configured.
