An attacker could exploit this vulnerability using man-in-the-middle techniques to impersonate a TLS server and obtain credentials.This vulnerability is commonly referred to as SLOTH". CVSS Base Score: 7.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109415 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N) CVEID: CVE-2016-0448 DESCRIPTION: An unspecified vulnerability in Oracle Java SE and Java SE Embedded related to the JMX component could allow a remote attacker to obtain sensitive information resulting in a partial confidentiality impact using unknown attack vectors. CVSS Base Score: 4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109949 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N) CVEID: CVE-2015-5041 DESCRIPTION: A flaw in the IBM J9 JVM allows code to invoke non-public interface methods under these circumstances. Untrusted code could potentially exploit this. This could lead to sensitive data being exposed to an attacker, or the attacker being able to inject bad data. CVSS Base Score: 4.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/106719 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N) CVEID: CVE-2015-7981 DESCRIPTION: libpng could allow a remote attacker to obtain sensitive information, caused by an out-of-bounds read in the png_convert_to_rfc1123 function.

Administrators can help to protect their Domino servers against unauthorized access by strictly limiting the use of Java functions on the server through careful population of the Programmability Restrictions section on the Security tab of the Server document. In particular, IBM recommends prohibiting server access by untrusted code, Java or otherwise. Likewise, administrators can use Policies to configure Notes Standard Client Execution Control Lists to limit such attacks against the Notes Standard client.
