Security Bulletin
Summary
The DOMConverter, JDOMConverter, DOM4JConverter, and XOMConverter functions in
Direct Web Remoting (DWR) through 2.0.10 and 3.x through 3.0.RC2 allow remote
attackers to read arbitrary files via DOM data containing an XML external
entity declaration in conjunction with an entity reference, related to an XML
External Entity (XXE) issue. Cross-site scripting (XSS) vulnerability in
Direct Web Remoting (DWR) through 2.0.10 and 3.x through 3.0.RC2 allows remote
attackers to inject arbitrary web script or HTML via unspecified vectors.
Vulnerability Details
CVEID: CVE-2014-5325
DESCRIPTION: Direct Web Remoting (DWR) could allow a remote attacker to obtain
sensitive information, caused by an XML External Entity Injection (XXE) error
when processing XML data. By sending specially-crafted XML data, an attacker
could exploit this vulnerability to obtain local system files and other
sensitive information.
CVSS Base Score: 4.3

CVEID: CVE-2014-5326
DESCRIPTION: Direct Web Remoting (DWR) is vulnerable to cross-site scripting,
caused by improper validation of user-supplied input. A remote attacker could
exploit this vulnerability using a specially-crafted URL to execute script in
a victim's Web browser within the security context of the hosting Web site,
once the URL is clicked. An attacker could use this vulnerability to steal the
victim's cookie-based authentication credentials.
