CWE-1066: Missing Serialization Control Element

What is Missing Serialization Control Element?

• Overview: Missing Serialization Control Element vulnerability occurs when a software product has a serializable data element without an associated serialization method, which can lead to runtime issues and potential vulnerabilities if exploited.

• Exploitation Methods:

• Attackers can exploit this vulnerability by causing unexpected behavior or exceptions during the serialization or deserialization process.
• Common attack patterns include crafting malicious serialized data that can crash the application or lead to unauthorized data manipulation.

• Security Impact:

• Direct consequences include application crashes or data corruption if serialization fails.
• Potential cascading effects involve denial of service attacks or further exploitation if the application exposes sensitive information.
• Business impact could include loss of service availability, data integrity issues, and damage to the organization's reputation.

• Prevention Guidelines:

• Specific code-level fixes include ensuring all serializable classes have proper serialization methods implemented.
• Security best practices involve validating serialized data before processing and securing serialization logic against manipulation.
• Recommended tools and frameworks include using serialization libraries that enforce strict data validation and adopting secure coding standards for serialization.
