Title: ESET Smart Security 'easdrv.sys' Local Privilege Escalation Vulnerability
Severity: HIGH
Description:
ESET Smart Security is security software with antivirus, antispam, and firewall protection.
ESET Smart Security is prone to a local privilege-escalation vulnerability in the 'easdrv.sys' driver. The problem occurs because the driver fails to check input and output pointers with the ProbeForRead or ProbeForWrite functions. This allows attackers to pass malicious user-mode code to arbitrary addresses within the kernel.
An attacker can exploit this issue to execute arbitrary code with kernel-level privileges on a Microsoft Windows host operating system. Successfully exploiting this issue will result in the complete compromise of affected computers. Failed exploit attempts will result in a denial-of-service condition.
ESET Smart Security 3.0.667.0 is vulnerable; other versions may also be affected.
Affected Products:
- Eset Software Smart Security 3.0.667.0
