The listed versions of AVEVA Plant SCADA and AVEVA Telemetry Server are vulnerable to an improper authorization exploit which could allow an unauthenticated user to remotely read data, cause denial of service, and tamper with alarm states.

AVEVA InTouch Access Anywhere versions 2020 R2 and older are vulnerable to a path traversal exploit that could allow an unauthenticated user with network access to read files on the system outside of the secure gateway web server.

AVEVA Software Platform Common Services (PCS) Portal versions 4.5.2, 4.5.1, 4.5.0, and 4.4.6 are vulnerable to DLL hijacking through an uncontrolled search path element, which may allow an attacker control to one or more locations in the search path.

Windows OS can be configured to overlay a “language bar” on top of any application. When this OS functionality is enabled, the OS language bar UI will be viewable in the browser alongside the AVEVA InTouch Access Anywhere and Plant SCADA Access Anywhere applications. It is possible to manipulate the Windows OS language bar to launch an OS command prompt, resulting in a context-escape from application into OS.
