Codesys ≫ Control Runtime System Toolkit

An authenticated, remote attacker may use a out-of-bounds write vulnerability in multiple CODESYS products in multiple versions to write data into memory which can lead to a denial-of-service condition, memory overwriting, or remote code execution.

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.

Improper Input Validation vulnerability in multiple CODESYS V3 products allows an authenticated remote attacker to block consecutive logins of a specific type.

In CmpChannelServer of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new communication channel connections. Existing connections are not affected.

In CmpBlkDrvTcp of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new TCP connections. Existing connections are not affected.

A remote, authenticated attacker could utilize the control program of the CODESYS Control runtime system to use the vulnerability in order to read and modify the configuration file(s) of the affected products.

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

An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally...

An unauthenticated, remote attacker can disrupt existing communication channels between CODESYS products by guessing a valid channel ID and injecting packets. This results in the communication channel to be closed.

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.
