Netsparker Identified Tomcat Web Server Exception Report in HTTP Responses

Netsparker identified an exception report disclosure (Tomcat) in the target web server's HTTP response.

Impact

An attacker can obtain information such as:
  • Tomcat version.
  • Physical file path of Tomcat files.
  • Information about the generated exception.
This information might help an attacker gain more information and potentially focus on the development of further attacks to the target system.

Remedy

Apply the following configuration to your web.xml file to prevent information leakage by applying custom error pages.
<error-page>
    <error-code>500</error-code>
    <location>/server_error.html</location>
</error-page>
