Design/Logic Flaw

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...

Out-of-bounds

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...

Input validation

In CODESYS Gateway Server V2 an insufficient check for the activity of TCP client connections allows an unauthenticated attacker to consume all available TCP connections and prevent legitimate users or clients from establishing a new connection to the CODESYS Gateway Server V2. Existing connectio...

Design/Logic Flaw

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...

Memory corruption

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...

Null pointer dereference

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...

Design/Logic Flaw

In CODESYS Gateway Server V2 for versions prior to V2.3.9.38 only a part of the the specified password is been compared to the real CODESYS Gateway password. An attacker may perform authentication by specifying a small password that matches the corresponding part of the longer real CODESYS Gatewa...

Design/Logic Flaw

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...

Out-of-bounds

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...

CVE-2022-32143

In CVE-2022-32143, multiple CODESYS products expose a file upload/download function that can access internal files in the working directory (e.g., PLC firmware). The issue is conditionally exploitable: requests are processed on the controller only if no level-1 password is configured or if the at...

CVE-2022-32143 CODESYS runtime system prone to directory acces

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...

CVE-2022-32142

CVE-2022-32142 affects multiple CODESYS products; an attacker with low privileges can craft requests with invalid offsets to trigger an out-of-bounds read/write, causing DoS or local memory overwrite and potentially changing local files. Descriptions consistently state no user interaction is requ...

CVE-2022-32141

CVE-2022-32141 involves multiple CODESYS products with a buffer over-read caused by insufficient internal buffer read limits when processing a request with an invalid offset. This enables a low-privilege, remote attacker to trigger a denial-of-service condition without user interaction. The avail...

CVE-2022-32140

CVE-2022-32140 affects multiple CODESYS products and describes a buffer overflow caused by an unchecked size during a buffer copy, allowing a low-privileged, remote attacker to trigger a denial-of-service condition without user interaction. The description indicates an attacker can craft a reques...

CVE-2022-32140 CODESYS runtime system prone to denial of service due to buffer copy

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-2022-32139

CVE-2022-32139 affects multiple CODESYS products. An attacker with low privileges can remotely craft a request that triggers an out-of-bounds read, causing a denial-of-service condition without user interaction. The NVD and CVE records describe the impact but do not provide concrete details on af...

CVE-2022-32139 CODESYS runtime system prone to denial of service due to out of bounds read

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...

CVE-2022-32138 CODESYS runtime system prone to denial of service due to Unexpected Sign Extension

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-2022-32138

CVE-2022-32138 affects multiple CODESYS products. A remote attacker can craft a request that triggers an unexpected sign extension, leading to denial-of-service or memory overwrite. The CVSS scores indicate high impact (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Affected detail on exact products, vers...

CVE-2022-32137 CODESYS Runtime System prone to heap based buffer overflow

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...
