Team82 has developed a novel technique called the Evil PLC Attack in which programmable logic controllers (PLCs) are weaponized and used to compromise engineering workstations. An attacker with a foothold on an engineering workstation can have access to anything else on the OT network to which an engineer connects that machine, including other PLCs.
CWE 287: Improper Authentication
An Improper Authentication vulnerability exists in Danfoss AK-SM8xxA Series, resulting in an authentication bypass. Install the latest patch with number 4.2 to remediate this vulnerability. This flaw could enable an attacker to generate a web report that discloses sensitive information such as internal IP addresses, usernames, store names, and other sensitive information.e
CVSS v3: 8.2
CWE-798 USE OF HARD-CODED CREDENTIALS:
In Optigo Networks ONS NC600 versions 4.2.1-084 through 4.7.2-330, an attacker could connect with the device's ssh server and utilize the system's components to perform OS command executions.
Optigo Networks recommends users implement at least one of the following additional mitigations:
CVSS v3: 9.8
CWE-78 Improper Neutralization of Special Elements used in an OS Command:
A remote unauthenticated attacker who has bypassed authentication could execute arbitrary OS commands to disclose, tamper with, destroy or delete information in Mitsubishi Electric smartRTU, or cause a denial-of service condition on the product.
Mitsubishi Electric Europe B.V. recommends that users take note of the following mitigation measures to minimize the risk of exploiting this vulnerability:
CVSS v3: 9.8
CWE-306: Missing Authentication for Critical Function:
A remote unauthenticated attacker may be able to bypass authentication by utilizing a specific API route to execute arbitrary OS commands.
Mitsubishi Electric Europe B.V. recommends that users take note of the following mitigation measures to minimize the risk of exploiting this vulnerability:
CVSS v3: 7.5
CWE-547 USE OF HARD-CODED, SECURITY-RELEVANT CONSTANTS:
Optigo Networks Visual BACnet Capture Tool and Optigo Visual Networks Capture Tool version 3.1.2rc11 are vulnerable to an attacker impersonating the web application service and mislead victim clients.
Optigo Networks recommends users to upgrade to the following:
CVSS v3: 7.5
