TS7700 - July 2019 and October 2019
Security Bulletin
Summary
There are multiple vulnerabilities in IBM SDKs Java Technology Edition,
Versions 7 and 8, as used by IBM Virtualization Engine TS7700. These issues
were disclosed as part of the IBM Java SDK updates in July 2019 and October
2019. IBM Virtualization Engine TS7700 has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2019-2989
DESCRIPTION: An unspecified vulnerability in Java SE could allow an
unauthenticated attacker to cause no confidentiality impact, high integrity
impact, and no availability impact.
CVSS Base score: 6.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
169295 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N)
CVEID: CVE-2019-2978
DESCRIPTION: An unspecified vulnerability in Java SE related to the Networking
component could allow an unauthenticated attacker to cause a denial of service
resulting in a low availability impact using unknown attack vectors.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
169284 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2019-2816
DESCRIPTION: Vulnerability in the Java SE, Java SE Embedded component of Oracle
Java SE (subcomponent: Networking). Supported versions that are affected are
Java SE: 7u221, 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Difficult to
exploit vulnerability allows unauthenticated attacker with network access via
multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks
of this vulnerability can result in unauthorized update, insert or delete
access to some of Java SE, Java SE Embedded accessible data as well as
unauthorized read access to a subset of Java SE, Java SE Embedded accessible
data. Note: This vulnerability applies to Java deployments, typically in
clients running sandboxed Java Web Start applications or sandboxed Java applets
(in Java SE 8), that load and run untrusted code (e.g., code that comes from
the internet) and rely on the Java sandbox for security. This vulnerability can
also be exploited by using APIs in the specified Component, e.g., through a web
service which supplies data to the APIs. CVSS 3.0 Base Score 4.8
(Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/
UI:N/S:U/C:L/I:L/A:N).
CVSS Base score: 4.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
163878 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2019-2762
DESCRIPTION: Vulnerability in the Java SE, Java SE Embedded component of Oracle
Java SE (subcomponent: Utilities). Supported versions that are affected are
Java SE: 7u221, 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Easily
exploitable vulnerability allows unauthenticated attacker with network access
via multiple protocols to compromise Java SE, Java SE Embedded. Successful
attacks of this vulnerability can result in unauthorized ability to cause a
partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note:
This vulnerability applies to Java deployments, typically in clients running
sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8),
that load and run untrusted code (e.g., code that comes from the internet) and
rely on the Java sandbox for security. This vulnerability can also be exploited
by using APIs in the specified Component, e.g., through a web service which
supplies data to the APIs. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS
Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/

Workarounds and Mitigations
Although IBM recommends that you upgrade to the fixes identified above, you can
mitigate, but not eliminate the risk of these vulnerabilities by restricting
physical and network access to the TS7700 to authorized users and IBM Service
Personnel only.
