Multiple vulnerabilities have been reported in IBM WebSphere Application Server, which can be exploited by malicious people to conduct cross-site scripting and cross-site request forgery attacks, hijack a user's session, disclose certain sensitive information, bypass certain security restrictions, and cause a DoS (Denial of Service).

1) Certain unspecified input related to the administrative console is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) An error when handling Secure Sockets Layer (SSL) packets can be exploited to cause a crash by a specially crafted SSL packet.

3) An error within the Administrative Console can be exploited to hijack a user's session.

4) Certain unspecified input is not properly verified before being used to access files. This can be exploited to read arbitrary files via directory traversal sequences.

5) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. to obtain certain sensitive information if a logged-in user visits a malicious web site.

6) An error in the proxy server component can be exploited to cause the proxy being marked as down via a specially crafted web request.

7) An input validation error in the Liberty Profile when using JAX-RS can be exploited to access otherwise restricted resources.

The vulnerabilities are reported in versions 6.1.0 through 6.1.0.43, 7.0 through 7.0.0.23, 8.0 through 8.0.0.3, and 8.5.
