Affected: Rockwell Automation ISaGRAF Runtime

Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x searches for and loads DLLs as dynamic libraries. Uncontrolled loading of dynamic libraries could allow a local, unauthenticated attacker to execute arbitrary code. This vulnerability only affects ISaGRAF Runtime when running on Microsoft Windows systems.

Some commands used by the ISaGRAF eXchange Layer (IXL) protocol perform various file operations in the file system. Since the parameter pointing to the file name is not checked for reserved characters, it is possible for a remote, unauthenticated attacker to traverse an application 's directory, which could lead to remote code execution.CVE-2020-25176 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:H/UI:N/S:C/C:H/I:H/A:H). ISaGRAF Runtime stores the password in plaintext in a file that is in the same directory as the executable file. ISaGRAF Runtime reads the file and saves the data in a variable without any additional modification. A local, unauthenticated attacker could compromise the user passwords, resulting in information disclosure.CVE-2020-25184 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:L/UI:N/S:U/C:H/I:H/A:H). ISaGRAF Workbench communicates with ISaGRAF Runtime using TCP/IP. This communication protocol provides various file system operations, as well as the uploading of applications. Data is transferred over this protocol unencrypted, which could allow a remote unauthenticated attacker to upload, read, and delete files.CVE-2020-25178 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:H/PR:N/UI:R/S:U/C:H/I:H/A:H). ISaGRAF Runtim…
