Description
This security bulletin contains information about 2 vulnerabilities.
1) Security restrictions bypass (CVE-ID: CVE-2016-8732)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to bypass security restrictions on the target system.
The weakness exists in the ‘InvProtectDrv.sys’ driver component due to weak restrictions on the driver communication channel and additonal insufficient checks. A local attacker can run a specially crafted application to turn off protection mechanisms and gain access to the system.
2) Insecure DLL loading (CVE-ID: CVE-2017-2802)
CWE-ID: CWE-427 - Uncontrolled Search Path Element
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists in the poaService.exe service component due to dll hijacking. A local attacker can place a specially crafted “atiadlxx.dll” file in one of directories pointed to by the PATH environment variable and execute arbitrary code on the target system with system privileges.
Successful exploitation of the vulnerability may result in system compromise.
