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

The specific function of HR Portal of Soar Cloud System accepts any type of object to be deserialized. Attackers can send malicious serialized objects to execute arbitrary commands.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Hr_portal Hr_portal_project 7.3.2020.1013 (including) 7.3.2020.1013 (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.
