Security Bulletin: Mulitiple security vulnerabilities in Apache CXF affects IBM InfoSphere Master Data Management (CVE-2016-6812 CVE-2016-8739 CVE-2017-5653 CVE-2017-5656 CVE-2017-3156)

Summary

IBM Initiate Master Data Service is vulnerable to multiple Apache CXF issues and could allow remote attackers to steal a victim’s cookie-based authentication credentials and read arbitrary files on the system.

Vulnerability Details

CVEID: CVE-2016-6812**
DESCRIPTION:** Apache CXF is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the FormattedServiceListWriter() function. A remote attacker could exploit this vulnerability using the 'matrix ’ parameter in 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.
