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.
