Summary In Pilz PMC programming tool 3.x before 3.5.17 (based on CODESYS Development System), the password-hashing feature requires insufficient computational effort. 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.
