Name of the Vulnerable Software and Affected Versions Advantech WebAccess/SCADA versions prior to 9.1.4

Description The issue is related to the use of untrusted pointers in the software. Specifically, the RPC arguments sent by the client could contain raw memory pointers that the server uses as-is. This could allow an attacker to gain access to the remote file system, enabling them to execute commands and overwrite files.

Recommendations For versions prior to 9.1.4, update to version 9.1.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the RPC functionality to minimize the risk of exploitation.
