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 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
