Edit Custom FilterAutomatic filtering via a Struts bean has been turned off, which disables the Struts Validator and custom validation logic. This exposes the application to other weaknesses related to insufficient input validation.

![]() Languages Java (Undetermined Prevalence) Example 1 This mapping defines an action for a download form: (bad code)
Example Language: XML
<action path="/download"
type="com.website.d2.action.DownloadAction" name="downloadForm" scope="request" input=".download" validate="false"> </action> This mapping has disabled validation. Disabling validation exposes this action to numerous types of attacks.
![]()
Other
The Action Form mapping in the demonstrative example disables the form's validate() method. The Struts bean: write tag automatically encodes special HTML characters, replacing a < with "<" and a > with ">". This action can be disabled by specifying filter="false" as an attribute of the tag to disable specified JSP pages. However, being disabled makes these pages susceptible to cross-site scripting attacks. An attacker may be able to insert malicious scripts as user input to write to these JSP pages.
