The Content-Security-Policy header enforces that the source of content, such as the origin of a script, embedded (child) frame, embedding (parent) frame or image, are trusted and allowed by the current web-page; if, within the web-page, a content's source does not adhere to a strict Content Security Policy, it is promptly rejected by the browser. 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. Non-cryptographically-secure pseudo-random number generators, while providing uniform output, are predictable, rendering them useless in certain cryptographic scenarios. There are traits in the response that can be used to identify technologies used in the backend server. The following code is an example of a simple class with a private variable. Regarding this, credit cards are a major concern. Unsafe Object Binding: Medium: Using object binding methods (built into MVC controllers and ORMs) exposes all public setters to allow easily wiring values submitted by users in forms, to the objects and attributes they are intended to create or alter. It's not a graceful approach and only fix this vulnerability. Insufficient Session Expiration occurs when a Web application permits an attacker to reuse old session credentials or session IDs for authorization.

The application is sending private information to the user although the 'Location' header and a redirect status code are being sent in the response by @DestinationElement in @DestinationFile at line @DestinationLine. XXE injection occurs when untrusted XML input containing a reference to an external entity is processed by a weakly configured XML parser. The user can access or modify a resource based on a request parameter, without a proper authorization check. Deserialization - OWASP Cheat Sheet Series What is Supply Chain Threat Intelligence? The victim then retrieves the malicious script from the server when it requests the stored information. An attacker can attempt and fail at logging into the application, without the application logging this suspicious activity. When a Command Injection vulnerability is caused by a stored input from a database or a file, the attack vector can be persistent. For the longest time the project went with a more permissible blacklist approach and would simply add forbidden gadgets/classes to the same list from time to time: However, newer fixes follow a more selective whitelist approach by introducing a PolymorphicTypeValidator class. Once the attacker gains the victim's session identifier, the attacker can perform any action in the application that the user is permitted, including accessing the user's personal data such as reading the user's records or changing the user account. Unrestricted Upload of File with Dangerous Size. Unsafe Object Binding: Medium: Using object binding methods (built into MVC controllers and ORMs) exposes all public setters to allow easily wiring values submitted by users in forms, to the objects and attributes they are intended to create or alter.
