Successful exploitation of these vulnerabilities may allow information disclosure, deletion of files, and remote code execution.
The following versions of Advantech Spectre RT Industrial Routers are affected:
The affected product does not neutralize special characters in the error response, allowing attackers to use a reflected XSS attack.
CVE-2019-18233 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N).
Login and password are transmitted in clear text form, which may allow an attacker to intercept the request.
CVE-2019-18231 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
Insufficient login authentication parameters required for the web application may allow an attacker to gain full access using a brute-force password attack.
CVE-2019-18235 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).
Outdated version of BusyBox password encryption is in use, which may allow an attacker to discover passwords.
CVE-2018-20679, CVE-2016-6301, CVE-2015-9261, and others have been assigned to this version of BusyBox. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
Outdated version of OpenSSL is in use, which may allow an attacker to exploit known vulnerabilities in OpenSSL.
CVE-2016-2842, CVE-2016-0799, CVE-2016-6304 and others have been assigned to this version of OpenSSL. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
