An authenticated, remote attacker may use a Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple versions of multiple CODESYS products to force a denial-of-service situation.

An authenticated, remote attacker may use a improper input validation vulnerability in the CmpApp/CmpAppBP/CmpAppForce Components of multiple CODESYS products in multiple versions to read from an invalid address which can lead to a denial-of-service condition.

Multiple CODESYS products in multiple versions are prone to a improper input validation vulnerability. An authenticated remote attacker may craft specific requests that use the vulnerability leading to a denial-of-service condition.

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.

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.

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.

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.

A bug in CmpUserMgr component can lead to only partially applied security policies. This can result in enabled, anonymous access to components part of the applied security policy.

An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.
