Multiple WAGO devices in multiple versions may allow an authenticated remote attacker with high privileges to DoS the device by sending a specifically crafted packet to the CODESYS V2 runtime.

Multiple WAGO devices in multiple versions may allow an authenticated remote attacker with high privileges to DoS the device by sending a malformed packet.

In CODESYS V3 products in all versions prior V3.5.16.0 containing the CmpUserMgr, the CODESYS Control runtime system stores the online communication passwords using a weak hashing algorithm. This can be used by a local attacker with low privileges to gain full control of the device.

On WAGO PFC200 devices in different firmware versions with special crafted packets an attacker with network access to the device could cause a denial of service for the login service of the runtime.

On WAGO PFC200 devices in different firmware versions with special crafted packets an authorised attacker with network access to the device can access the file system with higher privileges.
