The Administrative Console in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.45, 7.0 before 7.0.0.25, 8.0 before 8.0.0.5, and 8.5 before 8.5.0.1 allows remote attackers to hijack sessions via unspecified vectors.

IBM WebSphere Application Server (WAS) 6.1.x before 6.1.0.45, 7.0.x before 7.0.0.25, 8.0.x before 8.0.0.5, and 8.5.x Full Profile before 8.5.0.1, when the PM44303 fix is installed, does not properly validate credentials, which allows remote authenticated users to obtain administrative access via unspecified vectors.

Cross-site scripting (XSS) vulnerability in the Administrative Console in IBM WebSphere Application Server (WAS) 6.1.x before 6.1.0.45, 7.0.x before 7.0.0.25, 8.0.x before 8.0.0.4, and 8.5.x before 8.5.0.1 allows remote attackers to inject arbitrary web script or HTML via vectors involving FRAME elements, related to a cross-frame scripting (XFS) issue.

IBM Global Security Kit (aka GSKit), as used in IBM HTTP Server in IBM WebSphere Application Server (WAS) 6.1.x before 6.1.0.45, 7.0.x before 7.0.0.25, 8.0.x before 8.0.0.4, and 8.5.x before 8.5.0.1, allows remote attackers to cause a denial of service (daemon crash) via a crafted ClientHello message in the TLS Handshake Protocol.

IBM WebSphere Application Server (WAS) 6.0 through 6.0.2.43, 6.1 before 6.1.0.43, 7.0 before 7.0.0.23, and 8.0 before 8.0.0.3 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.

iscdeploy in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.43, 7.0 before 7.0.0.21, and 8.0 before 8.0.0.2 on the IBM i platform sets weak permissions under systemapps/isclite.ear/ and bin/client_ffdc/, which allows local users to read or modify files via standard filesystem operations.
