Security Bulletin
This security bulletin contains information about 9 vulnerabilities.
Updated 06.03.2020
Added vulnerability #9
EUVDB-ID: #VU23630
Risk: High
CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-5081
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the iocheckd service "I/O-Check" functionality within the ReadPCBManuNum message processing code. A remote attacker can send a specially crafted set of packets, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.

EUVDB-ID: #VU23639
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-5077
CWE-ID:
CWE-306 - Missing Authentication for Critical Function
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an insufficient authentication mechanism in the iocheckd service "I/O-Check" functionality. A remote attacker can send a specially crafted set of packets which will overwrite the MAC Address stored persistently on the device, cause a denial of service, resulting in the device entering an error state where it ceases all network communications.
