A flaw was found in the way JBoss RichFaces handled deserialization. A remote attacker could use this flaw to trigger the execution of the deserialization methods in any serializable class deployed on the server. This could lead to a variety of security impacts depending on the deserialization logic of these classes.
jboss-seam.jar in the JBoss Seam 2 framework 2.2.x and earlier, as distributed in Red Hat JBoss Enterprise SOA Platform 4.3.0.CP05 and 5.1.0; JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.3.0, 4.3.0.CP09, and 5.1.1; and JBoss Enterprise Web Platform 5.1.1, does not properly restrict use of Expression Language (EL) statements in FacesMessages during page exception handling, which allows remote attackers to execute arbitrary Java code via a crafted URL to an application. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1484.
jboss-seam.jar in the JBoss Seam 2 framework 2.2.x and earlier, as distributed in Red Hat JBoss Enterprise SOA Platform 4.3.0.CP04 and 5.1.0 and JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.3.0.CP09 and 5.1.0, does not properly restrict use of Expression Language (EL) statements in FacesMessages during page exception handling, which allows remote attackers to execute arbitrary Java code via a crafted URL to an application.
By using a specially crafted HTTP request, the first layer of authentication for the invoker servlets deployed by httpha-invoker can be bypassed, as the access restrictions only apply for GET and POST. Due to the second layer of authentication provided by the security interceptor, there is no way to directly exploit this flaw. If a user misconfigured the security interceptor or inadvertently disabled it, this flaw would be exploitable.
The fix is to remove the verb-specific <http-method> elements from web.xml. This issue is a regression of CVE-2010-0738.
wsf/common/DOMUtils.java in JBossWS Native in Red Hat JBoss Enterprise Application Platform 4.2.0.CP09, 4.3, and 5.1.1; JBoss Enterprise Portal Platform 4.3.CP06 and 5.1.1; JBoss Enterprise SOA Platform 4.2.CP05, 4.3.CP05, and 5.1.0; JBoss Communications Platform 1.2.11 and 5.1.1; JBoss Enterprise BRMS Platform 5.1.0; and JBoss Enterprise Web Platform 5.1.1 does not properly handle recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted request containing an XML document with a DOCTYPE declaration and a large number of nested entity references, a similar issue to CVE-2003-1564.
The JBoss Server in JBoss Enterprise Application Platform 5.1.x before 5.1.2 and 5.2.x before 5.2.2, Web Platform before 5.1.2, BRMS Platform before 5.3.0, and SOA Platform before 5.3.0, when the server is configured to use the JaccAuthorizationRealm and the ignoreBaseDecision property is set to true on the JBossWebRealm, does not properly check the permissions created by the WebPermissionMapping class, which allows remote authenticated users to access arbitrary applications.
JGroups diagnostics service in JBoss Enterprise Portal Platform before 5.2.2, SOA Platform before 5.3.0, and BRMS Platform before 5.3.0, is enabled without authentication when started by the JGroups channel, which allows remote attackers in adjacent networks to read diagnostics information via a crafted IP multicast.
