CVE-2018-18987

VT-Designer Version 2.1.7.31 is vulnerable by the program populating objects with user supplied input via a file without first checking for validity, allowing attacker supplied input to be written to known memory locations. This may cause the program to crash or allow remote code execution.

Weakness

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

Affected Software

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.
