CVE-2022-1965 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-10-26 5.5 MEDIUM 8.1 HIGH
Multiple products of CODESYS implement a improper error handling. A low privilege remote attacker may craft a request, which is not properly processed by the error handling. In consequence, the file referenced by the request could be deleted. User interaction is not required.
CVE-2021-34595 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-10-24 5.5 MEDIUM 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-2022-31805 1 Codesys 10 Development System, Edge Gateway, Gateway and 7 more 2022-09-23 4.3 MEDIUM 7.5 HIGH
In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected.
CVE-2022-31806 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-07-07 6.8 MEDIUM 9.8 CRITICAL
In CODESYS V2 PLCWinNT and Runtime Toolkit 32 in versions prior to V2.4.7.57 password protection is not enabled by default and there is no information or prompt to enable password protection at login in case no password is set at the controller.
CVE-2022-32143 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-07-01 6.5 MEDIUM 8.8 HIGH
In multiple CODESYS products, file download and upload function allows access to internal files in the working directory e.g. firmware files of the PLC. All requests are processed on the controller only if no level 1 password is configured on the controller or if remote attacker has previously successfully authenticated himself to the controller. A successful Attack may lead to a denial of service, change of local files, or drain of confidential Information. User interaction is not required
CVE-2022-32142 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-07-01 5.5 MEDIUM 8.1 HIGH
Multiple CODESYS Products are prone to a out-of bounds read or write access. A low privileged remote attacker may craft a request with invalid offset, which can cause an out-of-bounds read or write access, resulting in denial-of-service condition or local memory overwrite, which can lead to a change of local files. User interaction is not required.
CVE-2022-32141 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-07-01 4.0 MEDIUM 6.5 MEDIUM
Multiple CODESYS Products are prone to a buffer over read. A low privileged remote attacker may craft a request with an invalid offset, which can cause an internal buffer over-read, resulting in a denial-of-service condition. User interaction is not required.
CVE-2022-32138 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-07-01 6.5 MEDIUM 8.8 HIGH
In multiple CODESYS products, a remote attacker may craft a request which may cause an unexpected sign extension, resulting in a denial-of-service condition or memory overwrite.
CVE-2022-32139 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-07-01 4.0 MEDIUM 6.5 MEDIUM
In multiple CODESYS products, a low privileged remote attacker may craft a request, which cause an out-of-bounds read, resulting in a denial-of-service condition. User Interaction is not required.

Multiple CODESYS products are affected to a buffer overflow.A low privileged remote attacker may craft a request, which can cause a buffer copy without checking the size of the service, resulting in a denial-of-service condition. User Interaction is not required.
CVE-2022-32137 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-07-01 6.5 MEDIUM 8.8 HIGH
In multiple CODESYS products, a low privileged remote attacker may craft a request, which may cause a heap-based buffer overflow, resulting in a denial-of-service condition or memory overwrite. User interaction is not required.
CVE-2022-32136 1 Codesys 2 Plcwinnt, Runtime Toolkit 2022-07-01 4.0 MEDIUM 6.5 MEDIUM
In multiple CODESYS products, a low privileged remote attacker may craft a request that cause a read access to an uninitialized pointer, resulting in a denial-of-service. User interaction is not required.
