Objective: To cause a Denial of Service (DoS) in an application utilizing the textualize/rich
library by manipulating its input or exploiting vulnerabilities in its rendering or parsing logic.

Attack Tree Path: 1. Denial of Service (DoS)
Attack Tree Path: 1.1 Resource Exhaustion [CRITICAL]
This is a critical area because it represents a common and easily exploitable class of vulnerabilities. Applications using rich
must have robust defenses against resource exhaustion.
Attack Tree Path: 1.1.1 Excessive Console Output
- Description: The attacker provides input that causes
rich
to generate a very large amount of output to the console. This overwhelms the terminal, the application's output handling, or logging mechanisms, leading to a denial of service. - Example: A very long string, deeply nested
rich
objects (e.g., a Table with thousands of rows and columns), or repeated calls torich
printing functions with large amounts of data. - Likelihood: Medium
- Impact: Medium to High
- Effort: Low
- Skill Level: Novice
- Detection Difficulty: Easy
Attack Tree Path: 1.1.2 Excessive Memory Usage
- Description: The attacker crafts input that causes
rich
to consume a large amount of memory. This can lead to an out-of-memory (OOM) error, crashing the application. This might involve deeply nestedrich
objects or very long strings with complex formatting. - Example: A deeply nested structure of
rich
objects (e.g., Panels within Panels within Tables, etc., with many levels of nesting), or a very long string with many style changes. - Likelihood: Medium
- Impact: High
- Effort: Medium
- Skill Level: Intermediate
- Detection Difficulty: Medium
Attack Tree Path: 1.3 Crash via Input [CRITICAL]
This category is critical because crashes can lead to DoS.
Attack Tree Path: 1.3.1 Fuzzing Rich Objects
- Description: The attacker uses fuzzing techniques to send a large number of randomly generated or mutated
rich
objects (e.g.,Table
,Panel
,Text
,Console
) to the application. The goal is to find inputs that causerich
to crash due to unexpected internal states or unhandled exceptions. - Example: Using a fuzzer to generate random combinations of
rich
object properties, including invalid or out-of-range values. - Likelihood: Medium
- Impact: High
- Effort: Low
- Skill Level: Intermediate
- Detection Difficulty: Easy
