Trend Micro OfficeScan tmwfp Memory Corruption Privilege Escalation
Vulnerability
ZDI-17-828: September 27th, 2017
CVE ID
CVE-2017-14088
CVSS Score
6.9, (AV:L/AC:M/Au:N/C:C/I:C/A:C)
Affected Vendors
Trend Micro
Affected Products
OfficeScan
Vulnerability Details
This vulnerability allows local attackers to execute arbitrary code on
vulnerable installations of Trend Micro OfficeScan. 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 handling of IOCTL 0x220008 within
tmwfp.sys. The issue results from the lack of proper validation of
user-supplied data, which can result in a memory corruption condition. An
attacker can leverage this vulnerability to escalate privileges to resources
normally reserved for the kernel.
