A deserialization vulnerability in a .NET framework class used and not properly checked by Safety Designer all versions up to and including 1.11.0 allows an attacker to craft malicious project files. Opening/importing such a malicious project file would execute arbitrary code with the privileges of the current user when opened or imported by the Safety Designer. This compromises confidentiality integrity and availability. For the attack to succeed a user must manually open a malicious project file.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Safety_designer Sick * 1.11.0 (including)

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
