An unauthenticated remote attacker, who beats a race condition, can exploit a flaw in the communication servers of the CODESYS Control runtime system on Linux and QNX to trigger an out-of-bounds read via crafted socket communication, potentially causing a denial of service.
CVE-2025-41691 1 Codesys 1 Control 2026-04-15 7.5 High
An unauthenticated remote attacker may trigger a NULL pointer dereference in the affected CODESYS Control runtime systems by sending specially crafted communication requests, potentially leading to a denial-of-service (DoS) condition.
CVE-2025-41659 1 Codesys 1 Control 2026-04-15 8.3 High
A low-privileged attacker can remotely access the PKI folder of the CODESYS Control runtime system and thus read and write certificates and its keys. This allows sensitive data to be extracted or to accept certificates as trusted. Although all services remain available, only unencrypted communication is possible if the certificates are deleted.

A low-privileged remote attacker may be able to replace the boot application of the CODESYS Control runtime system, enabling unauthorized code execution.
CVE-2025-41738 1 Codesys 22 Control For Beaglebone Sl, Control For Empc-a/imx6 Sl, Control For Empc-a\/imx6 Sl and 19 more 2026-02-23 7.5 High
An unauthenticated remote attacker may cause the visualisation server of the CODESYS Control runtime system to access a resource with a pointer of wrong type, potentially leading to a denial-of-service (DoS) condition.
CVE-2025-41700 1 Codesys 2 Codesys, Development System 2026-02-23 7.8 High
An unauthenticated attacker can trick a local user into executing arbitrary code by opening a deliberately manipulated CODESYS project file with a CODESYS development system. This arbitrary code is executed in the user context.

Crafted web server requests may cause a heap-based buffer overflow and could therefore trigger a denial-of- service condition due to a crash in the CODESYS V2 web server prior to V1.1.9.22.
CVE-2021-34584 2 Codesys, Wago 55 Codesys, 750-8202, 750-8202 Firmware and 52 more 2025-08-15 9.1 Critical
Crafted web server requests can be utilised to read partial stack or heap memory or may trigger a denial-of- service condition due to a crash in the CODESYS V2 web server prior to V1.1.9.22.
CVE-2021-34585 2 Codesys, Wago 55 Codesys, 750-8202, 750-8202 Firmware and 52 more 2025-08-15 7.5 High
In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests can trigger a parser error. Since the parser result is not checked under all conditions, a pointer dereference with an invalid address can occur. This leads to a denial of service situation.
CVE-2021-34586 2 Codesys, Wago 55 Codesys, 750-8202, 750-8202 Firmware and 52 more 2025-08-15 7.5 High
