Rockwell Automation ISaGRAF Workbench software versions 6.0 through 6.6.9 are affected by a Deserialization of Untrusted Data vulnerability. ISaGRAF Workbench does not limit the objects that can be deserialized. This vulnerability allows attackers to craft a malicious serialized object that, if opened by a local user in ISaGRAF Workbench, may result in remote code execution. This vulnerability requires user interaction to be successfully exploited.

Rockwell Automation ISaGRAF Workbench software versions 6.0 through 6.6.9 are affected by a Path Traversal vulnerability. Crafted malicious files can allow an attacker to traverse the file system when opened by ISaGRAF Workbench. If successfully exploited, an attacker could overwrite existing files and create additional files with the same permissions of the ISaGRAF Workbench software. User interaction is required for this exploit to be successful.

Rockwell Automation ISaGRAF Workbench software versions 6.0 through 6.6.9 are affected by a Path Traversal vulnerability. A crafted malicious .7z exchange file may allow an attacker to gain the privileges of the ISaGRAF Workbench software when opened. If the software is running at the SYSTEM level, then the attacker will gain admin level privileges. User interaction is required for this exploit to be successful.

Connected Components Workbench (v13.00.00 and prior), ISaGRAF Workbench (v6.0 though v6.6.9), and Safety Instrumented System Workstation (v1.2 and prior (for Trusted Controllers)) do not limit the objects that can be deserialized. This allows attackers to craft a malicious serialized object that, if opened by a local user in Connected Components Workbench, may result in arbitrary code execution. This vulnerability requires user interaction to be successfully exploited

When opening a malicious solution file provided by an attacker, the application suffers from an XML external entity vulnerability due to an unsafe call within a dynamic link library file. An attacker could exploit this to pass data from local files to a remote web server, leading to a loss of confidentiality.

Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x 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.

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.

Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x includes the functionality of setting a password that is required to execute privileged commands. The password value passed to ISaGRAF Runtime is the result of encryption performed with a fixed key value using the tiny encryption algorithm (TEA) on an entered or saved password. A remote, unauthenticated attacker could pass their own encrypted password to the ISaGRAF 5 Runtime, which may result in information disclosure on the device.

ISaGRAF Workbench communicates with Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x 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.

Some commands used by the Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x 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.
