Summary:
Various application or web servers / products are prone to an information disclosure vulnerability.

Detection Method:
Sends a crafted HTTP GET request and checks the response.

Affected Versions:
The following products are known to be affected: - Atlassian Jira Server Other products might be affected as well.

Technical Details:
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').

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.

Recommendations:
The following vendor fixes are known: - Update Atlassian Jira Server to the latest available version. For other products please contact the vendor for more information on possible fixes.

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
