Vulnerability Details

CVE-2020-8602:  Deep Security Manager and Vulnerability Protection
Integrity Verification Bypass
CVSSv3.1: 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H)
A vulnerability in the affected products' management console may allow
an authenticated attacker with full control privileges to bypass file
integrity checks, leading to remote code execution.

CVE-2020-15601, CVE-2020-15605:  Deep Security Manager and Vulnerability
Protection LDAP Authentication Bypass
CVSSv3.1: 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
If LDAP authentication is enabled, an unauthenticated attacker with
prior knowledge of the targeted organization may be able to bypass
manager authentication.
Enabling multi-factor authentication prevents this attack.
Installations using manager native authentication or SAML authentication
are not impacted by this vulnerability.


Risk and Mitigating Factors

Exploiting these type of vulnerabilities generally require that an
attacker has access (physical or remote) to a vulnerable machine. In
addition to timely application of patches and updated solutions,
customers are also advised to review remote access to critical systems
and ensure policies and perimeter security is up-to-date.

The attacker must gain access to the manager web console to exploit
these vulnerabilities.  Mitigating factors such as network controls,
password complexity requirements and leveraging multi factor
authentication reduce the likelihood of attack.

Trend Micro is not aware of any active exploits related to these
vulnerabilities; however, we recommend that customers take immediate
action to remediate the issue.
