Rockwell Automation Studio 5000 Logix Designer Improper Restriction of Operations within the Bounds of a Memory Buffer

Omron CX-Position (versions 2.5.3 and prior) is vulnerable to memory corruption while processing a specific project file, which may allow an attacker to execute arbitrary code.

Use of hard-coded credentials vulnerability exists in Machine automation controller NJ series all models V 1.48 and earlier, Machine automation controller NX7 series all models V1.28 and earlier, Machine automation controller NX1 series all models V1.48 and earlier, Automation software 'Sysmac Studio' all models V1.49 and earlier, and Programmable Terminal (PT) NA series NA5-15W/NA5-12W/NA5-9W/NA5-7W models Runtime V1.15 and earlier, which may allow a remote attacker who successfully obtained the user credentials by analyzing the affected product to access the controller.

Authentication bypass by capture-replay vulnerability exists in Machine automation controller NX7 series all models V1.28 and earlier, Machine automation controller NX1 series all models V1.48 and earlier, and Machine automation controller NJ series all models V 1.48 and earlier, which may allow an adjacent attacker who can analyze the communication between the controller and the specific software used by OMRON internally to cause a denial-of-service (DoS) condition or execute a malicious program.

In all versions of Omron PLC CJ Series, an attacker can send a series of specific data packets within a short period, causing a service error on the PLC Ethernet module, which in turn causes a PLC service denied result.

Omron’s CS and CJ series PLCs have an unrestricted externally accessible lock vulnerability.

In Omron PLC CJ series, all versions, and Omron PLC CS series, all versions, an attacker could monitor traffic between the PLC and the controller and replay requests that could result in the opening and closing of industrial valves.

Omron CX-One CX-Programmer before 9.6, CJ2M PLC devices before 2.1, and CJ2H PLC devices before 1.5 rely on cleartext password transmission, which allows remote attackers to obtain sensitive information by sniffing the network during a PLC unlock request.

Vulnerability Related to an Uncontrolled Search Path Element in a UPS Management Application

It has been identified that a vulnerability (CWE-427) exists in the UPS (Uninterruptible Power Supply) management application, whereby improper permissions on the installation directory allow a malicious actor to place a DLL that is then executed with administrator privileges. If a malicious DLL is placed in the installation directory of this product, there is a possibility that the malicious DLL may be executed by exploiting the product’s behavior of loading missing DLLs from the same directory as the executable during service startup.

Buffer overflow in SGI Omron WorldView Wnn allows remote attackers to execute arbitrary commands via long JS_OPEN, JS_MKDIR, or JS_FILE_INFO commands.

Vulnerability caused by unquoted file paths of Windows services registered by the Uninterruptible Power Supply (UPS) management application

A vulnerability (CWE-428) has been identified in the Uninterruptible Power Supply (UPS) management application provided by OMRON SOCIAL SOLUTIONS Co., Ltd., where the executable file paths of Windows services are not enclosed in quotation marks. If the installation folder path of this product contains spaces, there is a possibility that unauthorized files may be executed under the service privileges by using paths containing spaces.

Out-of-bounds read vulnerability exists in CX-Programmer included in CX-One CXONE-AL[][]D-V4 Ver. 9.81 or lower. Opening a specially crafted project file may lead to information disclosure and/or the product being crashed.

Out-of-bounds Read vulnerability in CX-Programmer

Out-of-bounds Read vulnerability (CWE-125) was found in CX-Programmer. Attackers may be able to read sensitive information or cause an application crash by abusing this vulnerability.

Omron NS Series HMI Improper Neutralization of Input During Web Page Generation

Cross-site scripting (XSS) vulnerability in the web application on Omron NS5, NS8, NS10, NS12, and NS15 HMI terminals 8.1xx through 8.68x allows remote authenticated users to inject arbitrary web script or HTML via crafted data.

Omron NS Series HMI Cross-Site Request Forgery

Cross-site request forgery (CSRF) vulnerability in the web application on Omron NS5, NS8, NS10, NS12, and NS15 HMI terminals 8.1xx through 8.68x allows remote authenticated users to hijack the authentication of unspecified victims via unknown vectors.

Directory Traversal in Project File Format allows overwrite (Zip Slip)

Project files may contain malicious contents which the software will use to create files on the filesystem. This allows directory traversal and overwriting files with the privileges of the logged-in user.

Omron CJ-series and CS-series unauthenticated filesystem access.

An attacker with network access to the affected PLC (CJ-series and CS-series PLCs, all versions) may use a network protocol to read and write files on the PLC internal memory and memory card.

Out-of-bounds write vulnerability exists in CX-Programmer v.9.77 and earlier, which may lead to information disclosure and/or arbitrary code execution by having a user to open a specially crafted CXP file.

Use-after free vulnerability exists in CX-Programmer v.9.77 and earlier, which may lead to information disclosure and/or arbitrary code execution by having a user to open a specially crafted CXP file.

Stack-based buffer overflow vulnerability exists in CX-Programmer v.9.77 and earlier, which may lead to information disclosure and/or arbitrary code execution by having a user to open a specially crafted CXP file.

Executable files writable by low-privileged users in Omron Sysmac Studio

Sysmac Studio installs executables in a directory with poor permissions. This can allow a locally-authenticated attacker to overwrite files which will result in code execution with privileges of a different user.
