CWE-7—J2EE Misconfiguration: Missing Custom Error Page

Weakness Name

J2EE Misconfiguration: Missing Custom Error Page

Description

The default error page of a web application should not display sensitive information about the product.

A Web application must define a default error page for 4xx errors (e.g. 404), 5xx (e.g. 500) errors and catch java.lang.Throwable exceptions to prevent attackers from mining information from the application container's built-in error response. When an attacker explores a web site looking for vulnerabilities, the amount of information that the site provides is crucial to the eventual success or failure of any attempted attacks.

Common Consequences

Scope:

Confidentiality

Impact:

Read Application Data

Notes:

A stack trace might show the attacker a malformed SQL query string, the type of database being used, and the version of the application container. This information enables the attacker to target known vulnerabilities in these components.
