CA20190523-01: Security Notice for CA Risk Authentication and CA Strong
Authentication
Issued: May 23, 2019
Last Updated: May 23, 2019
The Support team for CA Technologies, A Broadcom Company, is alerting customers
to multiple potential risks with CA Risk Authentication and CA Strong
Authentication. Multiple vulnerabilities exist that can allow a remote attacker
to gain additional access in certain configurations or possibly gain sensitive
information. CA published solutions to address the vulnerabilities and
recommends that all affected customers implement these solutions immediately.
The first vulnerability, CVE-2019-7394, occurs due to insufficient verification
of custom privileges. A malicious actor, who has access to an account with
customized and limited privileges may, in some cases, access resources and act
outside of assigned privileges. This exposure does not affect installations
where accounts do not have custom privileges.
The second vulnerability, CVE-2019-7393, may enable a malicious actor to
conduct UI redress attacks to gain sensitive information in some cases.
