A CWE-502 Deserialization of Untrusted Data vulnerability exists in SCADAPack 7x Remote Connect (V3.6.3.574 and prior) which could allow arbitrary code execution when an attacker builds a custom .PRJ file containing a malicious serialized buffer.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Scadapack_7x_remote_connect Schneider-electric * 3.6.3.574 (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.
