CRITICAL 9.8EPSS 2.80%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.80%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

All versions prior to 9.1.4 of Advantech WebAccess/SCADA are vulnerable to use of untrusted pointers. The RPC arguments the client sent could contain raw memory pointers for the server to use as-is. This could allow an attacker to gain access to the remote file system and the ability to execute commands and overwrite files.
