Deserialization Attacks

What are Deserialization Attacks?

Deserialization Attacks occur when an attacker manipulates serialized data to execute malicious code or gain unauthorized access. Serialization is the process of converting an object into a format that can be stored or transmitted, and deserialization is the reverse process. If not handled securely, deserialization can lead to serious vulnerabilities.

How Deserialization Attacks Work

Deserialization Attacks typically involve the following steps:

• Vulnerability Identification: The attacker identifies a deserialization vulnerability in the target system.
• Payload Creation: The attacker creates a malicious payload and serializes it.
• Exploitation: The attacker sends the malicious payload to the target system, which deserializes it and executes the malicious code.

How to Defend Against Deserialization Attacks

To protect your systems from Deserialization Attacks, follow these best practices:

• Validate Input: Always validate and sanitize input before deserializing it.
• Use Secure Libraries: Use secure libraries and frameworks for serialization and deserialization.
• Implement Integrity Checks: Use digital signatures or checksums to verify the integrity of serialized data.
• Conduct Code Reviews: Review code for potential deserialization vulnerabilities and address them promptly.
