HPSBNS03625 rev.1 - HPE NonStop Application Server for Java (NSASJ) running SSL/TLS, Remote Disclosure of Information
NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.

Potential Security Impact: Remote Disclosure of Information

Source: Hewlett Packard Enterprise, HPE Product Security Response Team

VULNERABILITY SUMMARY

NonStop Application Server for Java (NSASJ) has addressed the cross-protocol Attack on TLS using SSLv2 also known as "DROWN". This vulnerability could be exploited remotely resulting in disclosure of information.

Note: NSASJ configurations that have enabled SSL/TLS are vulnerable if SSLv2 is enabled or they share private keys with systems that have it enabled.

RESOLUTION

HPE has released the following information to resolve the vulnerability in NonStop Application Server for Java (NSASJ).

To avoid the DROWN vulnerability, the SSLv2 protocol in NSASJ must explicitly disabled.

The security protocol support in NSASJ is applied through security Realm settings or through connectors that expose the interface. Disable the SSLv2 protocol either in the connector configuration or the security domain configuration as shown below.

Secure Connector HTTPS and TLS/SSL

  • To enable TLS/SSL support for a particular instance of a connector, the secure attribute must be set to true. TLS/SSL support is enabled in the default NSASJ HTTPS connector configuration.

  • Perform the following steps to complete the TLS/SSL setup:

    1. Create a certificate keystore:

      $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore /path/to/my/keystore

      Enter a password when prompted.

    2. Add a SSL tag in the connector configuration.

      If the protocol attribute is not specified, SSLv2 is supported by default. To disable SSLv2, specify the protocol attribute and do not include SSLv2.

The following is a sample configuration that enables only TLSv1.2:

<connector name="https" protocol="HTTP/1.1" scheme="https" socket binding="https" secure="true">
<ssl key-alias="tomcat" protocol="TLSv1.2" password="XXXX" certificate-key-file="/path/to/my/keystore"/>
</connector>

Due to protocol weaknesses, HPE also recommends to disable SSLv3 and TLSv1.0 by excluding them from the protocol list.

Applying security restrictions through Security Domains and Realms

  • Restricting access to all containers and management interfaces of NSASJ can be done by configuring security domains in appropriate Realms configured in domain.xml and host.xml files.

  • Each Realm has a server-identities tag which has an ssl element. The protocols attribute of this tag must be explicitly set to a protocol list that does not include SSLv2 in order to disable it.

The following is a sample configuration that enables only TLS 1.2:

<management>
<security-realms>
<security-realm name="ManagementRealm">
<server-identities>
<ssl protocol="TLSv1.2">
<keystore ..../>
</ssl>
</server-identities>
...
