Test ID:1.3.6.1.4.1.25623.1.0.117707
Category:Web Servers
Title:'/.//WEB-INF/' Information Disclosure Vulnerability (HTTP)
Summary:Various application or web servers / products are prone to an; information disclosure vulnerability.
Description:Summary:
Various application or web servers / products are prone to an
information disclosure vulnerability.

Vulnerability Insight:
The servlet specification prohibits servlet containers from
serving resources in the '/WEB-INF' and '/META-INF' directories of a web application archive
directly to clients.

This means that URLs like:

http://example.com/WEB-INF/web.xml

will return an error message, rather than the contents of the deployment descriptor.

However, some application or web servers / products are prone to a vulnerability that exposes this
information if the client requests a URL like this instead:

http://example.com/.//WEB-INF/web.xml

http://example.com/.//web-inf/web.xml

(note the './/' before 'WEB-INF').

Vulnerability Impact:
Based on the information provided in this file an attacker might
be able to gather additional info and/or sensitive data about the application / the application /
web server.

Affected Software/OS:
The following products are known to be affected:

- Payara Platform Enterprise / Community
