High impact if exploited, but EPSS currently rates exploitation as unlikely (0.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in Acuant AcuFill SDK before 10.22.02.03. Multiple MSI's get executed out of a standard-user writable directory. Through a race condition and OpLock manipulation, these files can be overwritten by a standard user. They then get executed by the elevated installer. This gives a standard user full SYSTEM code execution (elevation of privileges).
