Citrix ADC 内存泄露漏洞

漏洞信息

漏洞名称： Citrix ADC 内存泄露漏洞

漏洞编号：

• CVE： CVE-2025-5777

漏洞类型： 信息泄露

漏洞等级： 高危

漏洞描述： Citrix ADC是一种广泛使用的应用交付控制器，它提供了负载均衡、应用防火墙、SSL加速等功能，常见于企业级网络环境中，用于优化和保护应用程序的交付。由于其广泛的应用，Citrix ADC的安全性对许多组织至关重要。该漏洞被标记为’Citrix Bleed 2’，是一个假设性的内存泄露漏洞，编号为CVE-2025-5777。漏洞的根源在于处理特定类型的请求时，设备可能会泄露敏感信息，如会话令牌或JWT。攻击者可以通过发送特制的超大请求来触发这一漏洞，从而无需认证即可获取敏感数据。这种信息泄露可能导致进一步的攻击，如会话劫持或未授权访问。由于漏洞可能被远程利用且不需要用户交互，其潜在影响较大，尤其是在未打补丁的系统上。

Citrix Bleed 2 PoC Scanner (CVE-2025-5777)

This script is a Proof-of-Concept (PoC) scanner for the hypothetical vulnerability “Citrix Bleed 2” (CVE-2025-5777). It is designed to detect potential memory leaks from Citrix ADC devices by sending oversized requests and analyzing the responses for sensitive information.

Features

• Multiple Test Methods: Supports oversized-headers, oversized-body, and randomized testing methods.
• Differential Analysis: Compares test responses against a baseline to identify leaked data.
• High-Confidence Token Extraction: Uses regex and entropy analysis to find potential tokens (e.g., session cookies, JWTs).
• Multiple Export Formats: Can export findings to JSON, CSV, or raw text files.
• Configurable: Allows setting the number of requests, delay, and other options.

Installation

1. Clone the repository:

   git clone https://github.com/your-username/citrix-bleed-2-scanner.git
   cd citrix-bleed-2-scanner

2. Install dependencies:

   pip install -r requirements.txt

   (Note: You will need to create a requirements.txt file containing requests)

Usage

python citrix_bleed_2_scanner.py --target <TARGET_URL> [OPTIONS]

Examples

• Basic scan:

  python citrix_bleed_2_scanner.py --target https://192.168.1.100

• Loop with a delay:

  python citrix_bleed_2_scanner.py --target https://192.168.1.100 --loop 10 --delay 5

• Use a specific test method and export to JSON:

  python citrix_bleed_2_scanner.py --target https://192.168.1.100 --test-method oversized-body --json-out results.json

Options

Option	Description	Default
--target	Target URL (e.g., https://192.168.1.100)	Required
--loop	Number of requests to send	1
--delay	Delay between requests in seconds	2.0
--test-method	The testing method to use (randomized, oversized-headers, oversized-body)	randomized
--json-out	Export found tokens to a JSON file	None
--csv-out	Export found tokens to a CSV file	None
--raw-out	Export raw response content to a file	None
--no-insecure	Enable TLS certificate verification	disabled
