If an attacker submits maliciously crafted serialized data to exploit vulnerabilities in the deserialization process. Many times, the same bugs can be triggered by remote attackers to achieve arbitrary code execution capability on the vulnerable system. Javas inbuilt concept of serialization, does all this for you, for the very objects created by your application that are still in memory. Please address comments about this page to nvd@nist.gov. The data is validated as safe to the application.

Adobe Security Bulletin Heres an example of how this class can be done in practice: The example code shown would allow only the com.gypsyengineer.jackson type of objects to be deserialized. The encoding of data is taken care of by Javas inbuilt serialization libraries. With so many Java and .NET applications relying on serialization for storing and exchanging information, a greater risk surface is available to threat actors when applications lack basic input sanitization or are hosted on insufficiently secure servers (such as exposed ports or improperly authenticated API endpoints). In the first case, you might even not fix it and settle with the compensating controls. NIST does

Dealing with Deserialization of Untrusted Data in Java Applications BinaryFormatter is insecure and can't be made secure. It is the consumer's sole responsibility to determine whether to utilize BinaryFormatter. What makes serialization an appealing solution for developers is that storage, retrieval, and transmission of data becomes possible with a single command and without worrying about the underlying logic or platform. Successful insecure deserialization attacks could allow an attacker to carry out attacks such as DoS attacks, authentication bypasses, and remote code execution.

If you dont care about the human-readable aspect of the resulting file and merely want to store this data for retrieval by your application later, serialization can save you enormous time. This makes it possible for unauthenticated attackers to inject a PHP Object. .NET considers this behavior to be by design and won't issue a code update to modify the behavior. Last year we encountered the so-called java object deserialization vulnerability (not a java's problem as it looks), which is deserializing an object which might lead to Remote Code Execution (RCE) or Denial of Service (DoS) attacks. For example, say you have a Person class in Java that contains fields containing an individuals personal information, such as name, email address, phone number, and address. If you wanted to offer a save option to your users, you could either choose to iterate over the Person object, convert each field into an appropriate format, such as JSON or CSV, and output it to a file. Dell Security Advisories and NoticesDell Vulnerability Response PolicyCVSS Scoring Guide, DSA-2020-037: Dell Security Management Server Deserialization of Untrusted Data Vulnerability. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. An obvious approach is to perform basic input sanitization when parsing objects from a deserialized byte stream.
Second, you need to prioritize your suggestions: turning off serialization is the best option as it eliminates the risk. These attacks might render the app unresponsive or result in unexpected process termination. If an attacker submits maliciously crafted serialized data to exploit vulnerabilities in the deserialization process. An attacker can leverage this vulnerability to execute code in the context of the service account. Some classes have triggers that execute additional code when they are created in this manner; see SEC58-J.
2023-05-20: 7.5: . Vulnerability Disclosure
Successful attacks can result in the attacker being able to run code within the context of the target process. No POP chain is present in the vulnerable plugin. However, deserialized data or code can often be modified without using the provided accessor functions if it does not use cryptography to protect itself. Thus the attacker can leverage a cloud storage account compromise to gain full code execution permissions. For more information, see How to suppress code analysis warnings. Serialization refers to the process of saving an object's state as a sequence of bytes and conversely, deserialization is the process of rebuilding those bytes back into an object. This leads to a PHAR deserialization vulnerability on PHP < 8.0 using the phar:// stream wrapper.
