Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU16680
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-3989
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to information exposure in the 0x8200E804 IOCTL handler functionality when handling malicious input. A local attacker can use a specially crafted IRP request, cause the driver to return uninitialized memory and disclose kernel memory.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
The attacker would have to login to the system and perform certain actions in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU16679
Risk: Low
CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-3990
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to buffer overflow in the 0x8200E804 IOCTL handler functionality of WibuKey.sys when handling malicious input. A local attacker can use a specially crafted IRP request, trigger kernel memory corruption and gain elevated privileges.

EUVDB-ID: #VU16678
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-3991
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to heap-based buffer overflow in the WkbProgramLow function of WibuKey Network server management when handling malicious input. A remote attacker can supply a specially crafted TCP package, trigger memory corruption and execute kernel level code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
