1) Buffer overflow
EUVDB-ID: #VU11336
Risk: High
CVSSv3.1: 9.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]
CVE-ID: CVE-2018-0171
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote unauthenticated attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists in the Smart Install feature due to improper validation of packet data. A remote attacker can trigger buffer overflow, cause the service to crash and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
MitigationRockwell Automation recommends that users implement the following general security guidelines: - Help minimize network exposure for all control system devices and/or systems, and confirm that they are not accessible from the Internet. - Locate control system networks and devices behind firewalls, and isolate them from the business network. - When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
