CVE-2020-12006

Name of the Vulnerable Software and Affected Versions Advantech WebAccess Node versions 8.4.4 and prior Advantech WebAccess Node version 9.0.0

Description Multiple relative path traversal vulnerabilities exist that may allow a low privilege user to overwrite files outside the application’s control. The issue affects the WebAccess/SCADA system, including components such as DATACORE, ViewSrv, and DrawSrv, which are vulnerable to directory traversal and command injection attacks.

Recommendations For Advantech WebAccess Node versions 8.4.4 and prior, update to a version later than 8.4.4 to resolve the issue. For Advantech WebAccess Node version 9.0.0, update to a version later than 9.0.0 to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable IOCTL endpoints, such as 0x0000791e and 0x00002711, until a patch is available.
