CWEhttps://cwe.mitre.org/data/definitions/502.html

Elixir Plug before v1.0.4, v1.1.7, v1.2.3 and v1.3.2 is vulnerable to arbitrary code execution in the deserialization functions of Plug.Session.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Plug Plug_project 1.0.0 (including) 1.0.4 (excluding)
Plug Plug_project 1.1.0 (including) 1.1.7 (excluding)
Plug Plug_project 1.2.0 (including) 1.2.3 (excluding)
Plug Plug_project 1.3.0 (including) 1.3.2 (excluding)

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.
