CVE-2025-5777 PoC — Citrix NetScaler ADC和Citrix NetScaler Gateway 安全漏洞

Description

Update the old POC of CVE-2025-5777 Citrix NetScaler Memory leak

介绍

# CVE-2025-5777 – Citrix NetScaler Memory Leak (Updated PoC)

This repository contains an **updated Proof-of-Concept (PoC)** for exploiting **CVE-2025-5777** – a memory leak vulnerability affecting Citrix NetScaler.

The original PoC by [0xgh057r3c0n](https://github.com/0xgh057r3c0n/CVE-2025-5777) works perfectly,  
but some users reported connection errors due to **DNS issues, IPv6 quirks, or incorrect URL formats**.

### **What’s New in This Updated PoC**
- **Clearer error messages** for DNS failures and incorrect URLs
- **IPv4-only mode** by default to avoid IPv6 connectivity problems
- **Validation for `http://` or `https://` in the target URL**
- No changes to the **actual vulnerability logic** — the exploit works exactly the same
