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
Low
PR
The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file 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.

CA20200414-01: Security Notice for CA API Developer Portal
Issued: April 14th, 2020
Last Updated: April 14th, 2020
CA Technologies, A Broadcom Company, is alerting customers to multiple
vulnerabilities in CA API Developer Portal. Multiple vulnerabilities
exist that can allow attackers to bypass access controls, view or
modify sensitive information, perform open redirect attacks, or
elevate privileges. CA published solutions to address these
vulnerabilities and recommends that all affected customers implement
these solutions.
The first vulnerability, CVE-2020-11658, occurs due insecure handling
of shared secret keys. An attacker can bypass authorization.
The second vulnerability, CVE-2020-11659, occurs due to an access
control flaw. A privileged user can perform a restricted user
administration action.
The third vulnerability, CVE-2020-11660, occurs due to an access
control flaw. A privileged user can view restricted sensitive
information.
The fourth vulnerability, CVE-2020-11661, occurs due to an access
control flaw. A privileged user can view and edit user data.
The fifth vulnerability, CVE-2020-11662, occurs due to insecure
request handling. A remote attacker can exploit Cross-Origin Resource
Sharing to access sensitive information.
The sixth vulnerability, CVE-2020-11663, occurs due to insecure
redirect handling of 404 requests. An attacker can perform open
redirect attacks.
The seventh vulnerability, CVE-2020-11664, occurs due to insecure
redirect handling in the homeRedirect page. An attacker can perform
open redirect attacks.
The eighth vulnerability, CVE-2020-11665, occurs due to insecure
redirect handling in the loginRedirect page. An attacker can perform
open redirect attacks.
The ninth vulnerability, CVE-2020-11666, occurs due to an access
control flaw. A malicious user can elevate privileges.
