ThinkPHP v6.0.13 was discovered to contain a deserialization vulnerability via the component LeagueFlysystemCachedStoragePsr6Cache. This vulnerability allows attackers to execute arbitrary code via a crafted payload.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Thinkphp Thinkphp 6.0.13 (including) 6.0.13 (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.
