OpenSSL is used by Enterprise Content Management System Monitor has addressed the applicable CVEs. There are multiple vulnerabilities in IBM SDK Java Technology Edition, Version 6 and 7 that is used by IBM FileNet System Monitor/IBM Enterprise Content Management System Monitor.These issues were disclosed as part of the IBM Java SDK updates in January 2016 Vulnerability Details CVEID: CVE-2016-2107 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error when the connection uses an AES CBC cipher and the server support AES-NI. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to decrypt traffic.

Vulnerability Details Relevant CVE Information: CVEID: CVE-2016-5878 DESCRIPTION: IBM FileNet WorkPlace could allow a remote attacker to conduct phishing attacks, using an open redirect attack. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain highly sensitive information or conduct further attacks against the victim. CVSS Base Score: 6.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/115064 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:N) Affected Products and Versions FileNet Workplace 4.0.2 Remediation/Fixes Refer to the Workarounds and Mitigations section below. Workarounds and Mitigations First, upgrade to Workplace 4.0.2.14. Then, to avoid the Open Redirection vulnerability, ensure that only the Workplace Baseline URL is used to access pages. This is configured in the securityFilter.xml file, generally located in the install path under the Workplace/WEB-INF directory. List all applicable Workplace Baseline URLs in the urlWhitelist section. You may specify SSL and/or non-SSL URLs. <value>http://hostname:port/Workplace</value> <value>https://hostname:port/Workplace</value> Workplace Baseline URLs that are not included in the urlWhitelist section will be filtered out and not used.
