The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
None
C
There is no impact on the confidentiality of the system; the attacker does not gain the ability to read any data.
Integrity
None
I
There is no impact on the integrity of the system; the attacker does not gain the ability to modify any files or information on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.
EMC RecoverPoint SSL StrippingESA-2017-010: EMC RecoverPoint SSL Stripping Vulnerability
EMC Identifier: ESA-2017-010
CVE Identifier: CVE-2016-6650
Severity Rating: CVSS v3 Base Score: CVSS v3 Score: 6.8 (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N).
Affected products:
EMC RecoverPoint versions prior to 5.0
EMC RecoverPoint for Virtual Machines versions prior to 5.0
Summary:
EMC RecoverPoint update contains a fix for a SSL Stripping Vulnerability that may potentially be exploited by malicious users to compromise the affected system.
Details:
The Unisphere for RecoverPoint management interface does not enforce SSL encryption from the client side. A man-in-the-middle attacker may trick the Unisphere for RecoverPoint browser to send information like login credentials in plain text. RecoverPoint 5.0 now supports HTTP Strict Transport Security (HSTS) to mitigate this issue. It can be enabled with a configuration change. For more information, see RecoverPoints Security Configuration Guide and RecoverPoint for Virtual Machines Security Configuration Guide.
Resolution:
The following EMC RecoverPoint releases contain resolutions to these vulnerabilities:
EMC RecoverPoint 5.0
EMC RecoverPoint for Virtual Machines 5.0
EMC recommends all customers upgrade to one of the above versions at the earliest opportunity. Customers are strongly advised to limit administrator privileges to trusted users and change default passwords to minimize the risk. See Security Configuration Guide for details.
