CVE-2018-19650 : What You Need to Know

This CVE-2018-19650 article provides insights into a stack-based buffer overflow vulnerability in Antiy-AVL ATool security management v1.0.0.22 that could be exploited by local attackers to execute arbitrary code and potentially escalate privileges.

Understanding CVE-2018-19650

This vulnerability, identified as CVE-2018-19650, allows attackers to trigger a stack-based buffer overflow in vulnerable installations of Antiy-AVL ATool security management v1.0.0.22.

What is CVE-2018-19650?

The vulnerability arises from a flaw in the way the IRPFile.sys Antiy-AVL ATool kernel driver handles IOCTL 0x80002000, leading to a lack of proper validation of user-supplied data length.

The Impact of CVE-2018-19650

Exploiting this vulnerability enables attackers to execute arbitrary code within the kernel, potentially resulting in privilege escalation. A failed exploit could also lead to a denial of service condition.

Technical Details of CVE-2018-19650

This section delves into the technical aspects of the CVE-2018-19650 vulnerability.

Vulnerability Description

The vulnerability allows local attackers to trigger a stack-based buffer overflow in Antiy-AVL ATool security management v1.0.0.22 by exploiting the way IOCTL 0x80002000 is processed by the IRPFile.sys Antiy-AVL ATool kernel driver.

Affected Systems and Versions

Product: Antiy-AVL ATool security management v1.0.0.22
Vendor: Antiy-AVL
Version: 1.0.0.22

Exploitation Mechanism

The vulnerability can be exploited by local attackers who have the ability to execute low-privileged code on the target system. By manipulating user-supplied data length, attackers can trigger a kernel stack buffer overflow.
