Successful exploitation of these vulnerabilities could allow an attacker to read/modify information, execute arbitrary code, and/or crash the application.
The following versions of Industrial Automation CNCSoft ScreenEditor, an HMI, are affected:
Multiple stack-based buffer overflow vulnerabilities may be exploited by processing specially crafted project files, which may allow an attacker to read/modify information, execute arbitrary code, and/or crash the application.
CVE-2020-16199 has been assigned to these vulnerabilities. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
Multiple out-of-bounds read vulnerabilities may be exploited by processing specially crafted project files, which may allow an attacker to read information.
CVE-2020-16201 has been assigned to this vulnerability. A CVSS v3 base score of 3.3 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N).
An uninitialized pointer may be exploited by processing a specially crafted project file. Successful exploitation of this vulnerability may allow an attacker to read/modify information, execute arbitrary code, and/or crash the application.
CVE-2020-16203 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
