: A collection of Python scripts that use the CUCM AXL/SOAP APIs to extract phone inventory and registration data, which can be used for reconnaissance.

: Through the exposed phone web interfaces, the attacker downloads unencrypted configuration files. These files contain critical information, including the IP address of the CUCM server and, in some cases, cleartext SSH and LDAP credentials.

: One of the most prominent tools for attacking CUCM environments. It automates the discovery of IP phones and identifies the associated CUCM server. It exploits a common misconfiguration where phone configuration files containing plaintext SSH/admin credentials are stored on unencrypted TFTP servers. iCULeak.py

Attackers often exploit how CUCM delivers configuration files to VoIP phones via TFTP or HTTP. Cisco CUCM hacking -- GitHub

Cisco Unified Communications Manager (CUCM) is a popular call processing and routing system used in many enterprise networks. Like any complex software, it's not immune to potential security vulnerabilities.

: Vulnerabilities in the web-based management interface allow attackers to execute arbitrary commands by sending crafted HTTP requests, potentially elevating privileges to root. CLI Command Injection

While primarily for administrators, these tools are used in security contexts to audit configurations and automate compliance: unified_multi_path_traversal.py - GitHub

: A multi-threaded reconnaissance tool designed to find and extract credentials from CUCM environments. It enumerates targets through IP ranges, gowitness databases, or subnet scanning. It identifies registered phones by their MAC addresses ( SEP hostnames) and initiates parallelized TFTP/HTTP downloads to parse configuration XML payloads for embedded SSH credentials.

Place CUCM administration interfaces ( /ccmadmin ) inside a dedicated, firewalled Management VLAN accessible only via VPN or Jump Box.

: These tools can be used for malicious purposes, such as unauthorized access to CUCM systems or disruption of critical infrastructure.

Here is a timeline of CUCM vulnerabilities that had active GitHub repositories within days of disclosure.

Older, unpatched versions of CUCM suffer from directory traversal bugs. Public scripts on GitHub automate the process of exploiting these flaws to read sensitive configuration files, system logs, and cryptographic keys (such as tftp configuration files containing phone credentials). Phase 3: Post-Exploitation and Lateral Movement Can’t copy the link right now

Configure CUCM to encrypt phone configuration files, ensuring that even if a file is downloaded via TFTP, the contents remain unreadable to unauthorized parties. Patch Management and Monitoring

This guide explores how penetration testers leverage publicly available GitHub repositories to identify vulnerabilities, extract credentials, and audit Cisco CUCM environments. 1. Information Gathering and OSINT

The attack vector involved the following steps:
