CVE-2018-1306: Exposure of Sensitive Information in Apache Pluto

The PortletV3AnnotatedDemo Multipart Portlet war file code provided in Apache Pluto version 3.0.0 could allow a remote attacker to obtain sensitive information, caused by the failure to restrict path information provided during a file upload. An attacker could exploit this vulnerability to obtain configuration data and other sensitive information.

Root Cause Analysis

The vulnerability stems from improper path validation in the MultipartPortlet's file upload handler. The exploit demonstrates attackers can manipulate the 'filename' parameter to perform directory traversal (e.g., 'filename="../../../webapps/pluto/jspshell.jsp"'). This indicates the function responsible for processing uploaded files uses unsanitized user input to construct file paths. The PortletV3AnnotatedDemo's MultipartPortlet would logically contain the file upload handling code, and the processAction method (common in portlet lifecycle) would be where uploads are processed. The lack of path normalization/sanitization in this function matches the described CWE-200 exposure mechanism.
