TITLE

Advantech WebAccess/SCADA Arbitrary code execution vulnerability

Trust: 0.8

sources: IVD: d5dcd84f-1aca-4dc3-ac16-d5c7c3dd4d07 // CNVD: CNVD-2019-32473

DESCRIPTION

In WebAccess/SCADA Versions 8.3.5 and prior, multiple untrusted pointer dereference vulnerabilities may allow a remote attacker to execute arbitrary code. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the 0x2776 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment
