OmronCVEs & Vulnerabilities

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 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.

Two stack-based buffer overflow vulnerabilities have been discovered in CX-One Versions 4.42 and prior (CX-Programmer Versions 9.66 and prior and CX-Server Versions 5.0.23 and prior). When processing project files, the application allows input data to exceed the buffer. An attacker could use a specially crafted project file to overflow the buffer and execute code under the privileges of the application.

In CX-One Versions 4.42 and prior (CX-Programmer Versions 9.66 and prior and CX-Server Versions 5.0.23 and prior), when processing project files, the application 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.

A type confusion vulnerability exists when processing project files in Omron CX-Supervisor Versions 3.4.1.0 and prior, which may allow an attacker to execute code in the context of the application.

When processing project files in Omron CX-Supervisor Versions 3.4.1.0 and prior, the application fails to check if it is referencing freed memory, which may allow an attacker to execute code under the context of the application.

When processing project files in Omron CX-Supervisor Versions 3.4.1.0 and prior and tampering with the value of an offset, an attacker can force the application to read a value outside of an array.

When processing project files in Omron CX-Supervisor Versions 3.4.1.0 and prior and tampering with a specific byte, memory corruption may occur within a specific object.

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.

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, processing a malformed packet by a certain executable may cause an untrusted pointer dereference vulnerability.

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.

Omron CX-One CX-Programmer before 9.6, CJ2M PLC devices before 2.1, and CJ2H PLC devices before 1.5 use a reversible format for password storage in object files on Compact Flash cards, which makes it easier for local users to obtain sensitive information by reading a file.

Omron CX-One CX-Programmer before 9.6 uses a reversible format for password storage in project source-code files, which makes it easier for local users to obtain sensitive information by reading a file.

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.
