WebSphere Application Server 5.0.2 (or any earlier cumulative fix) stores admin and LDAP passwords in plaintext in the FFDC logs when a login to WebSphere fails, which allows attackers to gain privileges.

Unspecified vulnerability in IBM WebSphere Application Server 5.0.2 and earlier, and 5.1.1 and earlier, has unknown impact and attack vectors related to "Inserting certain script tags in urls [that] may allow unintended execution of scripts."

Unspecified vulnerability in IBM WebSphere 5.0.2.10 through 5.0.2.15 and 5.1.1.4 through 5.1.1.9 allows remote attackers to obtain sensitive information via unknown attack vectors, which causes JSP source code to be revealed.

IBM WebSphere Application Server (WAS) 5.0.2.5 through 5.1.1.3 allows remote attackers to obtain JSP source code and other sensitive information, related to incorrect request processing by the web container.

Double free vulnerability in the BBOORB module in IBM WebSphere Application Server for z/OS 5.0 allows attackers to cause a denial of service (ABEND).

IBM WebSphere 5.1 and WebSphere 5.0 allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a "Transfer-Encoding: chunked" header and a Content-Length header, which causes WebSphere to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka "HTTP Request Smuggling."

Buffer overflow in the administrative console in IBM WebSphere Application Server 5.x, when the global security option is enabled, allows remote attackers to execute arbitrary code.

Unknown vulnerability in IBM Websphere Application Server 5.0, 5.1, and 6.0 when running on Windows, allows remote attackers to obtain the source code for Java Server Pages (.jsp) via a crafted URL that causes the page to be processed by the file serving servlet instead of the JSP engine.

IBM WebSphere Application Server 6.0 and earlier, when sharing the document root of the web server, allows remote attackers to obtain the source code for Java Server Pages (.jsp) via an HTTP request with an invalid Host header, which causes the page to be processed by the web server instead of the JSP engine.
