Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2017-14153

High
7.8/10

Summary

This vulnerability allows local attackers to escalate privileges on Jungo WinDriver 12.4.0 and earlier. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of IOCTL 0x953824b7 by the windrvr1240 kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in a kernel pool overflow. An attacker can leverage this vulnerability to execute arbitrary code under the context of kernel.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
