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 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-2022-32140

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-2022-32139 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-2022-32139

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...

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

In CVE-2022-32137, multiple CODESYS products are affected by a heap-based buffer overflow that an unauthenticated, low-privilege remote attacker can trigger by crafting a request. This condition can result in a Denial of Service or a memory overwrite, with no user interaction required. The NVD en...

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...

CVE-2022-32136

CVE-2022-32136 affects multiple CODESYS products. A low-privilege remote attacker can craft a request to read an uninitialized pointer, causing a denial-of-service without user interaction. The root cause is dereferencing/uninitialized pointers. Impact is DoS; confidentiality/integrity unaffected...

CVE-2022-32136 Codesys runtime systems: Access of uninitialised pointer lead to denial of service.

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...

CVE-2022-31806
