IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.27, and 7.0 before 7.0.0.7, does not properly handle an exception occurring after use of wsadmin scripts and configuration of JAAS-J2C Authentication Data, which allows local users to obtain sensitive information by reading the First Failure Data Capture (FFDC) log file.

Unspecified vulnerability in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.27 allows remote attackers to cause a denial of service via unknown vectors, related to "an error in fixpacks 6.1.0.23 and 6.1.0.25."

The Migration component in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.25 and 7.0 before 7.0.0.5, when tracing is enabled and a 6.1 to 7.0 migration has occurred, allows remote authenticated users to obtain sensitive information by reading a Migration Trace file.

The Servlet Engine/Web Container component in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.25 and 7.0 before 7.0.0.5, when SPNEGO Single Sign-on (SSO) and disableSecurityPreInvokeOnFilters are configured, allows remote attackers to bypass authentication via a request for a "secure URL," related to a certain invokefilterscompatibility property.

The Web Services functionality in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.25 and 7.0 before 7.0.0.5, in certain circumstances involving the ibm-webservicesclient-bind.xmi file and custom password encryption, uses weak password obfuscation, which allows local users to cause a denial of service (deployment failure) via unspecified vectors.

The Security component in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.25 and 7.0 before 7.0.0.5 does not properly handle use of Identity Assertion with CSIv2 Security, which allows remote attackers to bypass intended CSIv2 access restrictions via vectors involving Enterprise JavaBeans (EJB).

The IBM Stax XMLStreamWriter in the Web Services component in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.25 does not properly process XML encoding, which allows remote attackers to bypass intended access restrictions and possibly modify data via "XML fuzzing attacks" sent through SOAP requests.

IBM WebSphere Application Server (WAS) 7.0 before 7.0.0.3, and the Feature Pack for Web Services for WAS 6.1 before 6.1.0.25, when a WS-Security policy is established at the operation level, does not properly handle inbound requests that lack a SOAPAction or WS-Addressing Action, which allows remote attackers to bypass intended access restrictions via a crafted request to a JAX-WS application.
