The Smart Slider 3 WordPress plugin before 3.5.1.11 unserialises the content of an imported file, which could lead to PHP object injection issues when a user import (intentionally or not) a malicious file, and a suitable gadget chain is present on the site.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Smart_slider_3 Nextendweb * 3.5.1.11 (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.
