CVSS v3 9.8
ATTENTION: Exploitable remotely/low skill level to exploit
Vendor: AVEVA Software, LLC. (AVEVA)
**Equipment:**InduSoft Web Studio and InTouch Edge HMI (formerly InTouch Machine Edition)
**Vulnerabilities:**Stack-based Buffer Overflow, Empty Password in Configuration File
Successful exploitation of these vulnerabilities could allow an unauthenticated user to remotely execute code.
AVEVA reports that these vulnerabilities affect the following products:
A remote attacker could send a carefully crafted packet to exploit a stack-based buffer overflow vulnerability during tag, alarm, or event related actions such as read and write, with potential for code to be executed. If InduSoft Web Studio remote communication security was not enabled, or a password was left blank, a remote user could send a carefully crafted packet to invoke an arbitrary process, with potential for code to be executed. The code would be executed under the privileges of the InduSoft Web Studio or InTouch Edge HMI runtime and could lead to a compromise of the InduSoft Web Studio or InTouch Edge HMI server machine.
CVE-2018-17916 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
This vulnerability could allow an unauthenticated user to remotely execute code with the same privileges as that of the InduSoft Web Studio or InTouch Edge HMI (formerly InTouch Machine Edition) runtime.
CVE-2018-17914 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
