This external control vulnerability, if exploited, could allow a local OS-authenticated user with standard privileges to delete files with System privilege on the machine where these products are installed, resulting in denial of service.
This privilege escalation vulnerability, if exploited, cloud allow a local OS-authenticated user with standard privileges to escalate to System privilege on the machine where these products are installed, resulting in complete compromise of the target machine.
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.
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.
