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.

The Web Server Plug-in in IBM WebSphere Application Server (WAS) 8.0 and earlier uses unencrypted HTTP communication after expiration of the plugin-key.kdb password, which allows remote attackers to obtain sensitive information by sniffing the network, or spoof arbitrary servers via a man-in-the-middle attack.

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.

The JavaServer Faces (JSF) application functionality in IBM WebSphere Application Server 8.x before 8.0.0.1 does not properly handle requests, which allows remote attackers to read unspecified files via unknown vectors.

Directory traversal vulnerability in the administration console in IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.41, 7.0 before 7.0.0.19, and 8.0 before 8.0.0.1 allows remote attackers to read arbitrary files via a .. (dot dot) in the URI.

Oracle Mojarra 1.2_14 and 2.0.2, as used in IBM WebSphere Application Server, Caucho Resin, and other applications, does not properly handle an unencrypted view state, which allows remote attackers to conduct cross-site scripting (XSS) attacks or execute arbitrary Expression Language (EL) statements via vectors that involve modifying the serialized view object.
