Omron CX-One

The Omron CX-One Version 4.60 and prior may allow an attacker to supply a pointer to arbitrary memory locations, which may allow an attacker to remotely execute arbitrary code.

Omron CX-One

This vulnerability allows local attackers to execute arbitrary code due to the lack of proper validation of user-supplied data, which can result in a type-confusion condition in the Omron CX-One Version 4.60 and prior devices.

When processing project files, the application (Omron CX-Programmer v9.70 and prior and Common Components January 2019 and prior) fails to check if it is referencing freed memory. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.

In Omron PLC CS series, all versions, Omron PLC CJ series, all versions, and Omron PLC NJ series, all versions, the software does not implement sufficient measures to prevent multiple failed authentication attempts within in a short time frame, making it more susceptible to brute force attacks.

In Omron PLC CJ series, all versions and Omron PLC CS series, all versions, an attacker could spoof arbitrary messages or execute commands.

In Omron CX-Supervisor, Versions 3.5 (12) and prior, Omron CX-Supervisor ships with Teamviewer Version 5.0.8703 QS. This version of Teamviewer is vulnerable to an obsolete function vulnerability requiring user interaction to exploit.

The application (Network Configurator for DeviceNet Safety 3.41 and prior) searches for resources by means of an untrusted search path that could execute a malicious .dll file not under the application's direct control and outside the intended directories.

Parsing malformed project files in Omron CX-One versions 4.42 and prior, including the following applications: CX-FLnet versions 1.00 and prior, CX-Protocol versions 1.992 and prior, CX-Programmer versions 9.65 and prior, CX-Server versions 5.0.22 and prior, Network Configurator versions 3.63 and prior, and Switch Box Utility versions 1.68 and prior, may cause a heap-based buffer overflow.

Parsing malformed project files in Omron CX-One versions 4.42 and prior, including the following applications: CX-FLnet versions 1.00 and prior, CX-Protocol versions 1.992 and prior, CX-Programmer versions 9.65 and prior, CX-Server versions 5.0.22 and prior, Network Configurator versions 3.63 and prior, and Switch Box Utility versions 1.68 and prior, may allow the pointer to call an incorrect object resulting in an access of resource using incompatible type condition.

In Omron CX-Supervisor Versions 3.30 and prior, processing a malformed packet by a certain executable may cause an untrusted pointer dereference vulnerability.

In Omron CX-Supervisor Versions 3.30 and prior, parsing malformed project files may cause a double free vulnerability.

In Omron CX-Supervisor Versions 3.30 and prior, use after free vulnerabilities can be exploited when CX Supervisor parses a specially crafted project file.

In Omron CX-Supervisor Versions 3.30 and prior, parsing malformed project files may cause a heap-based buffer overflow.

In Omron CX-Supervisor Versions 3.30 and prior, parsing malformed project files may cause an out of bounds vulnerability.

In Omron CX-Supervisor Versions 3.30 and prior, access of uninitialized pointer vulnerabilities can be exploited when CX Supervisor indirectly calls an initialized pointer when parsing malformed packets.

Parsing malformed project files in Omron CX-One versions 4.42 and prior, including the following applications: CX-FLnet versions 1.00 and prior, CX-Protocol versions 1.992 and prior, CX-Programmer versions 9.65 and prior, CX-Server versions 5.0.22 and prior, Network Configurator versions 3.63 and prior, and Switch Box Utility versions 1.68 and prior, may cause a stack-based buffer overflow.

In Omron CX-Supervisor Versions 3.30 and prior, parsing malformed project files may cause a stack-based buffer overflow.

OMRON NS devices 1.1 through 1.3 allow remote attackers to bypass authentication via a direct request to the .html file for a specific screen, as demonstrated by monitor.html.

Three type confusion vulnerabilities exist in CX-One Versions 4.50 and prior and CX-Protocol Versions 2.0 and prior when processing project files. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.

When CX-Supervisor (Versions 3.42 and prior) processes project files and tampers with the value of an offset, an attacker can force the application to read a value outside of an array.
