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 |
In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests may cause a Null pointer dereference in the CODESYS web server and may result in a denial-of-service condition. | ||||
CVE-2021-34593 | 2 Codesys, Wago | 28 Plcwinnt, Runtime Toolkit, 750-8202 and 25 more | 2025-08-15 | 7.5 High |
In CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56 unauthenticated crafted invalid requests may result in several denial-of-service conditions.

CVE-2021-34595 | 2 Codesys, Wago | 57 Codesys, Plcwinnt, Runtime Toolkit and 54 more | 2025-08-15 | 8.1 High |
A crafted request with invalid offsets may cause an out-of-bounds read or write access in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition or local memory overwrite. | ||||
CVE-2021-34596 | 2 Codesys, Wago | 57 Codesys, Plcwinnt, Runtime Toolkit and 54 more | 2025-08-15 | 6.5 Medium |
A crafted request may cause a read access to an uninitialized pointer in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition. | ||||
CVE-2021-30186 | 2 Codesys, Wago | 56 Plcwinnt, Runtime Toolkit, 750-8202 and 53 more | 2025-08-15 | 7.5 High |
CODESYS V2 runtime system SP before 2.4.7.55 has a Heap-based Buffer Overflow. | ||||
CVE-2025-41658 | 1 Codesys | 1 Control | 2025-08-05 | 5.5 Medium |

CVE-2025-41659 | 1 Codesys | 1 Control | 2025-08-05 | 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. | ||||
CVE-2025-41691 | 1 Codesys | 1 Control | 2025-08-05 | 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. |
