CVE-2017-18019

CWE-20Published: January 4, 2018· Updated: Jun 17, 2026

7.1

CVSS v3.1

Official Description

In K7 Total Security before 15.1.0.305, user-controlled input to the K7Sentry device is not sufficiently sanitized: the user-controlled input can be used to compare an arbitrary memory address with a fixed value, which in turn can be used to read the contents of arbitrary memory. Similarly, the product crashes upon a \\.\K7Sentry DeviceIoControl call with an invalid kernel pointer.

Technical Analysis

CVE-2017-18019 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), availability disruption (denial of service), with a CVSS base score of 7.1.

A proof-of-concept (PoC) exploit exists for CVE-2017-18019. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
