JBOSS 3.2.2 through 3.2.7 and 4.0.2 allows remote attackers to obtain sensitive information via a GET request (1) with a "%." (percent dot), which reveals the installation path or (2) with a % (percent) before a filename, which reveals the contents of the file.
JBoss Enterprise Application Platform (aka JBossEAP or EAP) before 4.2.0.CP03, and 4.3.0 before 4.3.0.CP01, allows remote attackers to obtain sensitive information about "deployed web contexts" via a request to the status servlet, as demonstrated by a full=true query string.
