Struts2 Development Mode Enabled

Severity: Low
Summary#

Invicti detected Struts2 development mode is enabled, so the target web server is disclosing stack trace data in the HTTP response.

Development mode enables extra debugging behaviors that assist developers, as well as attackers.

Impact#
An attacker can obtain information such as:
  • Stack trace.
  • Information about the generated exception.
This information might help an attacker gain more information and potentially to focus on the development of further attacks to the target system.
Remediation#
Change your WEB-INF/classes/struts.properties file to disable development mode:
	struts.devMode=false
OR
