New Update ESET releases crucial product updates that fix security vulnerabilities for Windows AMSI

[Gandalf_The_Grey]

ESET has released a bunch of product updates across the stack which fix a local privilege escalation (LPE) vulnerability that affected its products. The problem stemmed in the Windows Antimalware Scan Interface (AMSI) scanning feature, and the exploitation of it by threat actors could lead to LPE.

The firm says:

[...] an attacker who is able to get SeImpersonatePrivilege can misuse the AMSI scanning feature to elevate to NT AUTHORITY\SYSTEM in some cases.

ESET was made aware of the flaw by Trend Micro's Zero Day Initiative (ZDI) and the vulnerability has been assigned the ID CVE-2021-37852.
