Title
Improper Synchronization in Monitoring in CODESYS Control Runtime
Summary
Affected products do not properly synchronize access to their monitoring functionality. When multiple clients send concurrent requests, this may lead to incorrect reads or writes, or to corruption of internal memory structures. An authenticated remote attacker with monitoring access can exploit this issue to cause incorrect data processing or a denial-of-service condition.

VAR-201902-0731
Vulnerability from variot - Updated: 2025-10-04 21:15Use of Insufficiently Random Values exists in CODESYS V3 products versions prior V3.5.14.0. CODESYS The product contains an insufficient random value usage vulnerability.Information may be obtained. 3S-Smart CODESYS Control for BeagleBone, etc. are all German 3S-Smart Software Solutions company's programming software for industrial control system development.
A number of 3S-Smart Software Solutions products have security vulnerabilities that result from programs using values with insufficient randomness. An attacker could use this vulnerability to affect the confidentiality and integrity of the data. The following products are affected: 3S-Smart 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 RTE V3; CODESYS Control RTE V3 (for Beckhoff CX); CODESYS Control Win V3 (part of CODESYS Development System setup); CODESYS Control V3 Runtime System Toolkit; CODESYS V3 Embedded Target Visu Toolkit; CODESYS V3 Remote Target Visu Toolkit; CODESYS V3 Safety SIL2; CODESYS Gateway V3; CODESYS HMI V3; CODESYS OPC Server V3; CODESYS PLCHandler SDK; CODESYS V3 Development System; CODESYS V3 Simulation Runtime (part of CODESYS Development System). 3S-Smart Software CODESYS is prone to the following security vulnerabilities: 1. An insecure random number generator weakness 3. A spoofing vulnerability An attacker can exploit these vulnerabilities to bypass security restrictions and perform certain unauthorized actions and to insert and display spoofed content. Other attacks are also possible

VAR-201902-0732
Vulnerability from variot - Updated: 2025-10-04 20:15Improper Communication Address Filtering exists in CODESYS V3 products versions prior V3.5.14.0. CODESYS V3 There are unspecified vulnerabilities in the product.Information may be obtained. 3S-Smart CODESYS Control for BeagleBone, etc. are all German 3S-Smart Software Solutions company's programming software for industrial control system development.
A security vulnerability exists in several 3S-Smart Software Solutions products, which stems from programs that do not properly restrict communication channels. An attacker could use this vulnerability to impersonate the source of a communication packet. The following products are affected: 3S-Smart 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 RTE V3, CODESYS Control RTE V3 (for Beckhoff CX), CODESYS Control Win V3 (part of CODESYS Development System setup), CODESYS Control V3 Runtime System Toolkit, CODESYS V3 Embedded Target Visu Toolkit, CODESYS V3 Remote Target Visu Toolkit, CODESYS V3 Safety SIL2, CODESYS Gateway V3, CODESYS HMI V3, CODESYS OPC Server V3, CODESYS PLCHandler SDK, CODESYS V3 Development System, CODESYS V3 Simulation Runtime (part of CODESYS Development System). 3S-Smart Software CODESYS is prone to the following security vulnerabilities: 1. An insecure random number generator weakness 3. A spoofing vulnerability An attacker can exploit these vulnerabilities to bypass security restrictions and perform certain unauthorized actions and to insert and display spoofed content. Other attacks are also possible
