Insecure Deserialization
Insecure deserialization occurs when an application converts serialized data (a stream of bytes representing an object's state) back into a living object without proper validation.
How It Works
Insecure deserialization occurs when an application converts serialized data (a stream of bytes representing an object's state) back into a living object without proper validation. Serialization frameworks in languages like Java, PHP, Python, and .NET allow objects to be transformed into byte streams for storage or transmission, then reconstructed later. The vulnerability arises because deserialization can trigger code execution through the object's methods during reconstruction.
Attackers exploit this by crafting malicious serialized payloads containing specially chosen objects that chain together through "gadget chains" — sequences of method calls in existing application libraries. When the application deserializes the attacker's payload, it automatically invokes these methods in sequence, ultimately achieving arbitrary code execution. For example, in Java applications, an attacker might create a serialized object that, when deserialized, triggers a chain through Apache Commons Collections classes, ending in runtime command execution.
The attack typically begins with identifying an endpoint that accepts serialized data — often in cookies, API parameters, or message queue payloads. The attacker then uses tools like ysoserial (Java) or phpggc (PHP) to generate weaponized payloads targeting known gadget chains in the application's dependencies. Because deserialization happens automatically and often before any application logic executes, these attacks frequently bypass authentication and input validation.
Impact
- Remote code execution — attackers gain complete control of the server, executing arbitrary system commands
- Authentication bypass — deserializing manipulated user/session objects grants unauthorized access without credentials
- Privilege escalation — modifying serialized role or permission objects to gain administrative access
- Data exfiltration — reading sensitive files or database contents through executed code
- Denial of service — crafting objects that consume excessive memory or CPU during deserialization
Real-World Examples
SolarWinds Web Help Desk suffered two separate deserialization vulnerabilities in rapid succession. CVE-2025-40551 allowed unauthenticated attackers to achieve remote code execution by sending malicious serialized Java objects to the application. Even after patching, researchers discovered a second deserialization flaw in the same product, demonstrating how deeply embedded these vulnerabilities can be in application architectures.
Jenkins automation servers have experienced multiple Java deserialization vulnerabilities where attackers exploited the CLI protocol to send crafted objects, gaining full control over build servers. These attacks were particularly severe because Jenkins instances often have extensive network access and stored credentials for deploying applications.
WordPress and other PHP applications have faced attacks through unserialize() vulnerabilities in plugins, where attackers embedded malicious PHP objects in user-controllable data fields. Successful exploitation enabled attackers to install backdoors by writing arbitrary PHP files to the web root.
Mitigation
- Avoid deserializing untrusted data entirely — redesign systems to use data-only formats like JSON instead of native serialization
- Implement strict allowlists — configure deserialization libraries to only accept explicitly permitted classes, blocking all others
- Apply cryptographic signatures — sign serialized data and validate signatures before deserialization to ensure integrity
- Use isolated environments — deserialize in sandboxed processes with minimal privileges to contain potential exploitation
- Update vulnerable libraries — patch frameworks and remove dependencies with known gadget chains
- Monitor deserialization activity — log and alert on deserialization operations, especially from external sources
