🦉 Prototype Pollution

The following vulnerabilities are fixed with an upgrade:

@secure-code-warrior-for-github

Micro-Learning Topic: Prototype pollution (Detected by phrase)

Matched on "Prototype Pollution"

What is this? (2min video)

By adding or modifying attributes of an object prototype, it is possible to create attributes that exist on every object, or replace critical attributes with malicious ones. This can be problematic if the software depends on existence or non-existence of certain attributes, or uses pre-defined attributes of object prototype (such as hasOwnProperty, toString or valueOf).

Code Injection

Start Code Injection Lab

Description

Code Injection, also known as Remote Code Execution (RCE), is possible when unsafe user-supplied data is used to run server-side code. This is typically as a result of an application executing code without prior validation, thus allowing an attacker to execute arbitrary code within the context of the vulnerable application.

Not to be confused with OS Command Injection, Code Injection attacks allow the attacker to add their own code to be executed by the application, whereas OS Command Injection extends the preset functionality of the application to execute system commands, usually within the context of a shell.

Code Injection attacks are only limited by the functionality of the language the attacker has injected i.e. not very limited at all! If PHP code is the language chosen for the injection and is executed successfully, the attacker has every utility available in PHP at her/his disposal.

The Code Injection attack category encompasses multiple types of injection attacks, all of which are very prevalent and capable of extremely high levels of compromise. Indeed, OWASP has listed injection attacks as one of the most dangerous web application security risk since 2013.

Impact

Malicious attackers can leverage Code Injection vulnerabilities to gain a foothold in the hosting infrastructure, pivot to connected systems throughout the organization, execute unauthorized commands, and fully compromise the confidentiality, integrity, and availability of the application. Depending on the injection, this can usually lead to the complete compromise of the underlying operating system.

The list of devastating Code Injection attacks, both public and behind closed doors, is far too long to list. Hot off the press in 2020, this Code Injection discovery was shown to affect the default Mail application on stock iPhones and iPads, resulting in remote code execution.

In this particular instance, the vulnerability was identified by a security company which notified the vendor, Apple, of the issue. However, it is important as a developer to internalize the glaring reality that poorly written, unsecure code opens the way for attackers to potentially wreak havoc, which is why learning secure codeing skills from the beginning can potentially prevent an employer-destroying headline down the track.

Prevention

Code Injection attacks leveraging any language can be avoided by simply following some basic, yet essential, security practices. Overarching these general practices is the rule that a developer should treat all data as untrusted.

Developers must not dynamically generate code that can be interpreted or executed by the application using user-provided data. Evaluating code that contains user input should only be implemented if there is no other way of achieving the same result without code execution.

Testing

Verify that the application avoids the use of eval() or other dynamic code execution features. Where there is no alternative, any user input being included must be sanitized or sandboxed before being executed.

Micro-Learning Topic: OS command injection (Detected by phrase)

Matched on "OS Command Injection"

What is this? (2min video)

In many situations, applications will rely on OS provided functions, scripts, macros and utilities instead of reimplementing them in code. While functions would typically be accessed through a native interface library, the remaining three OS provided features will normally be invoked via the command line or launched as a process. If unsafe inputs are used to construct commands or arguments, it may allow arbitrary OS operations to be performed that can compromise the server.

Micro-Learning Topic: Code injection (Detected by phrase)

Matched on "Code Injection"

What is this? (2min video)

Code injection happens when an application insecurely accepts input that is subsequently used in a dynamic code evaluation call. If insufficient validation or sanitisation is performed on the input, specially crafted inputs may be able to alter the syntax of the evaluated code and thus alter execution. In a worst case scenario, an attacker could run arbitrary code in the server context and thus perform almost any action on the application server.

Micro-Learning Topic: Injection attack (Detected by phrase)

Matched on "Injection attack"

Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.
