CWE-600 Detail

The Servlet does not catch all exceptions, which may reveal sensitive debugging information.

When a Servlet throws an exception, the default error response the Servlet container sends back to the user typically includes debugging information. This information is of great value to an attacker. For example, 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.

Phases : Implementation
Implement Exception blocks to handle all types of Exceptions.

Vulnerability Mapping Notes

Justification : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

NotesNotes

The "Missing Catch Block" concept is probably broader than just Servlets, but the broader concept is not sufficiently covered in CWE.
