Cisco Cucm Hacking -- Github Jun 2026

: A multi-threaded tool designed to automatically download and parse Cisco phone configuration files from TFTP or HTTP servers. It can extract SSH credentials, usernames, and passwords that are often stored in plaintext. iCULeak.py

: The AXL API, while powerful for automation, has its own vulnerabilities. CVE-2023-20116 is a denial-of-service (DoS) vulnerability in the AXL API of CUCM that can be triggered by sending crafted HTTP input. Although DoS is less severe than RCE, it can still disrupt business-critical voice communications.

The Cisco "Security By Default" (SBD) feature, introduced in CUCM version 8.0, provides a baseline of security by enabling ITL (Identity Trust List) files and the TVS (Trust Verification Service), which help secure phone-CUCM communication.

Attackers can gain initial access through various means. Unpatched vulnerabilities are a common entry point. Exposed web management interfaces, especially those accessible from internal networks without proper segmentation, are frequently targeted. Tools and scripts available on GitHub have automated the discovery of these weaknesses, turning complex exploits into simple, one-command operations. In one real-world example during an internal recon, an attacker identified exposed VOIP phone web interfaces using an Nmap script to grep for specific HTTP titles. : A multi-threaded tool designed to automatically download

The open-source community provides custom Nmap Scripting Engine (NSE) scripts on GitHub designed to probe CUCM nodes. These scripts audit specific vulnerabilities or misconfigurations: nmap -p 8443 --script cisco-ucm-info Use code with caution.

Before any exploitation occurs, attackers use GitHub-sourced tools to map out Cisco telephony infrastructure. CUCM environments often expose web interfaces, Session Initiation Protocol (SIP) ports, and administrative services that leak version information. Footprinting via Shodan and Censys Python Frameworks Attackers can gain initial access through various means

If the CUCM version is outdated, the auditor looks for a matching PoC script on GitHub. These scripts automate the formatting of malicious payloads (such as directory traversal paths or malformed network packets) and send them to the target server. Step 3: Privilege Escalation and Persistence

GitHub contains numerous older tools (such as Viproy or custom VoIP pentesting frameworks) that leverage CUCM access to push malicious XML services to physical desk phones.

This Python-based repository provides scripts to exploit an authenticated SQL injection vulnerability (CVE-2019-15972) in Cisco Unified Call Manager. The scripts first enumerate all tables on the underlying database and then extract the contents of each table. The vulnerability was documented by F‑Secure, which highlighted how the Informix database used by CUCM could be targeted through specially crafted SQL queries. This repository serves as both a learning resource for security researchers and a ready‑to‑use tool for attackers.
