Official Description
The ESET Personal Firewall NDIS filter (EpFwNdis.sys) driver in the Firewall Module Build 1183 (20140214) and earlier in ESET Smart Security and ESET Endpoint Security products 5.0 through 7.0 allows local users to gain privileges via a crafted argument to a 0x830020CC IOCTL call.
Technical Analysis
CVE-2014-4973 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
