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.
This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Unified Automation UaGateway. Authentication is required to exploit this vulnerability.
The specific flaw exists within the implementation of the ImportXML function. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.

CWE-22 Path Traversal
A path traversal vulnerability exists in the Xibo CMS whereby a specially crafted zip file can be uploaded to the CMS via the layout import function by an authenticated user which would allow creation of files outside of the CMS library directory as the webserver user. This can be used to upload a PHP webshell inside the web root directory and achieve remote code execution as the webserver user.
CVSS V3: 8.8
CWE-89 SQL Injection:
An SQL injection vulnerability was discovered in the /dataset/data/{id} API route inside the CMS. This allows an authenticated user to exfiltrate data from the Xibo database by injecting specially crafted values in to the filter parameter.
Values allowed in the filter parameter are checked against a deny list of commands that should not be allowed, however this checking was done in a case sensitive manor and so it is possible to bypass these checks by using unusual case combinations.
CVSS V3: 6.5
CWE-89 SQL Injection:
A SQL injection vulnerability was discovered in the nameFilter function used throughout the CMS. This allows an authenticated user to exfiltrate data from the Xibo database by injecting specially crafted values for logical operators.
CVSS V3: 6.5
CWE-89 SQL Injection:
A SQL injection vulnerability was discovered in the /display/map API route inside the CMS. This allows an authenticated user to exfiltrate data from the Xibo database by injecting specially crafted values in to the bounds parameter.
