PHOENIX CONTACT: Two Vulnerabilities in Automation Worx Suite
Manipulated PC Worx projects could lead to a remote code execution due to insufficient input data validation. The attacker needs to get access to an original PC Worx project to be able to manipulate data inside the project folder. After manipulation the attacker needs to exchange the original files by the manipulated ones 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. In addition, we recommend exchanging or storing project files together with a checksum to ensure their integrity.
