The JMX Remoting functionality in Apache Geronimo 3.x before 3.0.1, as used in IBM WebSphere Application Server (WAS) Community Edition 3.0.0.3 and other products, does not properly implement the RMI classloader, which allows remote attackers to execute arbitrary code by using the JMX connector to send a crafted serialized object.

Apache Geronimo 2.2.1 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. NOTE: this might overlap CVE-2011-4461.

Apache Axis2 before 1.5.2, as used in IBM WebSphere Application Server (WAS) 7.0 through 7.0.0.12, IBM Feature Pack for Web Services 6.1.0.9 through 6.1.0.32, IBM Feature Pack for Web 2.0 1.0.1.0, Apache Synapse, Apache ODE, Apache Tuscany, Apache Geronimo, and other products, does not properly reject DTDs in SOAP messages, which allows remote attackers to read arbitrary files, send HTTP requests to intranet servers, or cause a denial of service (CPU and memory consumption) via a crafted DTD, as demonstrated by an entity declaration in a request to the Synapse SimpleStockQuoteService.

Multiple cross-site scripting (XSS) vulnerabilities in the web administration console in Apache Geronimo Application Server 2.1 through 2.1.3 allow remote attackers to inject arbitrary web script or HTML via the (1) name, (2) ip, (3) username, or (4) description parameter to console/portal/Server/Monitoring; or (5) the PATHINFO to the default URI under console/portal/.

Multiple cross-site request forgery (CSRF) vulnerabilities in the web administration console in Apache Geronimo Application Server 2.1 through 2.1.3 allow remote attackers to hijack the authentication of administrators for requests that (1) change the web administration password, (2) upload applications, and perform unspecified other administrative actions, as demonstrated by (3) a Shutdown request to console/portal//Server/Shutdown.

The init script for Apache Geronimo on SUSE Linux follows symlinks when performing a chown operation, which might allow local users to obtain access to unspecified files or directories.

The login method in LoginModule implementations in Apache Geronimo 2.0 does not throw FailedLoginException for failed logins, which allows remote attackers to bypass authentication requirements, deploy arbitrary modules, and gain administrative access by sending a blank username and password with the command line deployer in the deployment module.
