AhnLab V3 Anti-Virus v3flt2k.sys DeviceIoControl() Local Privilege Escalation
Local Access Required
Loss of Integrity
Various AhnLab V3 products contain a flaw that may allow a malicious user to gain access to unauthorized privileges. The problem is that the 'v3flt2k.sys' real-time scan driver does not validate the source of received 'DeviceIoControl()' commands, which may allow a malicious user to run 'explorer.exe' with SYSTEM privileges and/or disable the scan engine with specially crafted 'DeviceIoControl' requests resulting in a loss of integrity.
Upgrade to version 22.214.171.1247 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
