CVSS v3 9.8
ATTENTION: Exploitable remotely/low skill level to exploit
Vendor: Entes
**Equipment:**EMG 12
Vulnerabilities: Improper Authentication, Information Exposure Through Query Strings in GET Request
Successful exploitation of these vulnerabilities may allow attackers to gain unauthorized access and could allow the ability to change device configuration and settings.
The following versions of EMG 12, an Ethernet Modbus Gateway, are affected:
The application uses a web interface where it is possible for an attacker to bypass authentication with a specially crafted URL. This could allow for remote code execution.
CVE-2018-14826 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
An information exposure through query strings vulnerability in the web interface has been identified, which may allow an attacker to impersonate a legitimate user and execute arbitrary code.
CVE-2018-14822 has been assigned to this vulnerability. A CVSS v3 base score of 9.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
