Cross-site scripting (XSS) vulnerability in IBM WebSphere Portal 8.5.0 before CF03 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

IBM WebSphere Portal 6.1.0 through 6.1.0.6 CF27, 6.1.5 through 6.1.5.3 CF27, 7.0 through 7.0.0.2 CF28, 8.0 through 8.0.0.1 CF14, and 8.5.0 before CF03 provides different web-server error codes depending on whether a requested file exists, which allows remote attackers to determine the validity of filenames via a series of requests.

Cross-site request forgery (CSRF) vulnerability in IBM WebSphere Portal 8.5.0 before CF03 allows remote attackers to hijack the authentication of arbitrary users for requests that insert XSS sequences.

IBM WebSphere Portal 6.1.0 through 6.1.0.6 CF27, 6.1.5 through 6.1.5.3 CF27, 7.0 through 7.0.0.2 CF28, 8.0 before 8.0.0.1 CF14, and 8.5.0 through 8.5.0.0 CF02 allows remote authenticated users to discover credentials by reading HTML source code.

IBM WebSphere Portal 6.1.0 through 6.1.0.6 CF27, 6.1.5 through 6.1.5.3 CF27, 7.0.0 through 7.0.0.2 CF28, 8.0.0 through 8.0.0.1 CF13, and 8.5.0 before CF02 allows remote authenticated users to cause a denial of service (disk consumption) by uploading large files.

Cross-site scripting (XSS) vulnerability in IBM WebSphere Portal 8.0.0 through 8.0.0.1 CF13 and 8.5.0 before CF02 allows remote authenticated users to inject arbitrary web script or HTML via a crafted URL.

Open redirect vulnerability in IBM WebSphere Portal 6.1.0.0 through 6.1.0.6 CF27, 6.1.5.0 through 6.1.5.3 CF27, 7.0.0 through 7.0.0.2 CF28, 8.0.0 before 8.0.0.1 CF13, and 8.5.0 before CF01 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a crafted URL.

IBM WebSphere Portal 8.0.0 before 8.0.0.1 CF13 and 8.5.0 through CF01 provides different error codes for firewall-traversal requests depending on whether the intranet host exists, which allows remote attackers to map the intranet network via a series of requests.
