K70321874: Oracle Java SE vulnerability CVE-2018-2795

Security Advisory

Original Publication Date: May 12, 2018

Security Advisory Description

Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle
Java SE (subcomponent: Security). Supported versions that are affected are Java
SE: 6u181, 7u171, 8u162 and 10; Java SE Embedded: 8u161; JRockit: R28.3.17.
Easily exploitable vulnerability allows unauthenticated attacker with network
access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit.
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,
JRockit. Note: Applies to client and server deployment of Java. This
vulnerability can be exploited through sandboxed Java Web Start applications
and sandboxed Java applets. It can also be exploited by supplying data to APIs
in the specified Component without using sandboxed Java Web Start applications
or sandboxed Java applets, such as through a web service. 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). (CVE-2018-2795)

Impact

BIG-IP / BIG-IQ / F5 iWorkflow / Enterprise Manager / Traffix SDC

An attacker may cause a partial denial of service (DoS) to the affected Java
component when the vulnerability is exploited.

ARX / LineRate

There is no impact; these F5 products are not affected by this vulnerability.

Security Advisory Status

F5 Product Development has assigned ID 717742 and 717745 (BIG-IP), ID 718146

^1 The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.

^2 The specified products contain the affected code. However, F5 identifies the
vulnerability status as Not vulnerable because the attacker cannot exploit the
code in default, standard, or recommended configurations.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.

Mitigation

BIG-IP, BIG-IQ, iWorkflow, and Enterprise Manager

To mitigate this vulnerability, you should permit connectivity access to the
affected F5 products only over a secure network and restrict access for the
affected systems to only trusted users. For more information, refer to the
following articles:

  * K13309: Restricting access to the Configuration utility by source IP
    address (11.x - 13.x)
  * K13092: Overview of securing access to the BIG-IP system
  * K31401771: Restricting access to the BIG-IQ or F5 iWorkflow user interface
    by source IP address
