CODESYS Gateway any version

An issue was discovered in 3S-Smart CODESYS V3 products. The CODESYS Gateway does not correctly verify the ownership of a communication channel. All variants of the following CODESYS V3 products in all versions prior to v3.5.14.20 that contain the CmpGateway component are affected, regardless of the CPU type or operating system: CODESYS Control for BeagleBone, CODESYS Control for emPC-A/iMX6, CODESYS Control for IOT2000, CODESYS Control for Linux, CODESYS Control for PFC100, CODESYS Control for PFC200, CODESYS Control for Raspberry Pi, CODESYS Control V3 Runtime System Toolkit, CODESYS Gateway V3, CODESYS V3 Development System.

An issue was discovered in 3S-Smart CODESYS V3 products. A crafted communication request may cause uncontrolled memory allocations in the affected CODESYS products and may result in a denial-of-service condition. All variants of the following CODESYS V3 products in all versions prior to v3.5.14.20 that contain the CmpGateway component are affected, regardless of the CPU type or operating system: CODESYS Control for BeagleBone, CODESYS Control for emPC-A/iMX6, CODESYS Control for IOT2000, CODESYS Control for Linux, CODESYS Control for PFC100, CODESYS Control for PFC200, CODESYS Control for Raspberry Pi, CODESYS Control V3 Runtime System Toolkit, CODESYS Gateway V3, CODESYS V3 Development System.

Improper Communication Address Filtering exists in CODESYS V3 products versions prior V3.5.14.0.

Use of Insufficiently Random Values exists in CODESYS V3 products versions prior V3.5.14.0.

An issue was discovered in 3S-Smart CODESYS before 3.5.15.0 . Crafted network packets cause the Control Runtime to crash.

CODESYS Gateway 3 before 3.5.16.70 has a NULL pointer dereference that may result in a denial of service (DoS).

Communication Components in multiple CODESYS products vulnerable to communication channel disruption

CODESYS Gateway server prone to denial of service attack due to excessive memory allocation

CODESYS Control Runtime system before 3.5.17.0 has improper input validation. Attackers can send crafted communication packets to change the router's addressing scheme and may re-route, add, remove or change low level communication packages.

Insecure transmission of credentials

In CODESYS Gateway V3 before 3.5.17.10, there is a NULL Pointer Dereference. Crafted communication requests may cause a Null pointer dereference in the affected CODESYS products and may result in a denial-of-service condition.

CODESYS V3: CmpBlkDrvTcp allows unauthenticated attackers to block all its available TCP connections

CODESYS: CmpChannelServer, CmpChannelServerEmbedded allow unauthenticated attackers to block all their available communication channels

Untrusted Pointer Dereference in multiple CODESYS products can lead to a DoS.

CODESYS Control V3, Gateway V3, and HMI V3 before 3.5.15.30 allow uncontrolled memory allocation which can result in a remote denial of service condition.

Null Pointer Dereference in multiple CODESYS products can lead to a DoS.
