PHOENIX CONTACT: Security Advisory for Automation Worx Software Suite
Manipulated PC Worx or Config+ projects could lead to a remote code execution when unallocated memory is freed because of incompletely initialized data (CWE-824). The attacker needs to get access to an original bus configuration file (*.bcp) to be able to manipulate data inside. After manipulation the attacker needs to exchange the original file by the manipulated one on the application programming workstation.

- Mitigation
We strongly recommend customers to exchange project files only using secure file exchange services. Project files should not be exchanged via unencrypted email.
