Cisco Cucm Hacking -- Github Now

Repository examples: cucm-creds, AXL-SQL-injection

CUCM uses an API called AXL (Administrative XML Layer). Many old versions (12.x and below) are vulnerable to SQL injection or weak SOAP authentication.

As Cisco moves toward cloud-based Webex Calling and UCM Cloud, on-prem CUCM will slowly age. But enterprises have a 10–15 year lifecycle for telephony. During that time, GitHub will remain the go-to source for CUCM hacking techniques.

To answer the search query “Cisco CUCM hacking -- GitHub”: Yes, the tools exist. Yes, they work. And yes, your phone system is likely vulnerable if you haven't patched CVE-2023-20200 or enforced MFA on the AXL interface.

The best defense is not hiding from GitHub—it is using the same code to break your own system before the bad guys do.

Cisco Unified Communications Manager (CUCM) security research often centers on misconfigurations that expose sensitive data, particularly via phone configuration files. On GitHub, security professionals and researchers host various tools and scripts designed to audit, exploit, or secure these environments. Notable GitHub Tools for CUCM Security Auditing

Researchers use these tools to identify common attack vectors such as credential leakage and improper API access.

SeeYouCM-Thief: A popular multi-threaded tool that automatically downloads and parses configuration files from Cisco phone systems. It searches for SSH credentials, passwords, and usernames often stored in plaintext. It also includes features for MAC address brute-forcing and user enumeration via the CUCM User Data Services (UDS) API. Find it here: SeeYouCM-Thief on GitHub.

iCULeak.py: A focused Python script that extracts credentials from phone configuration files stored on TFTP servers. It specifically addresses issues where browsers or password managers might autofill sensitive CUCM credentials into configuration fields. Find it here: iCULeak.py on GitHub.

Routersploit (CUCM Modules): This exploitation framework contains modules specifically for CUCM, such as the unified_multi_path_traversal.py script, which exploits path traversal vulnerabilities to read files from the filesystem.

Cisco-UCM-SQLi-Scripts: A collection of scripts used to exploit CVE-2019-15972, an authenticated SQL injection (SQLi) vulnerability in earlier versions of CUCM. Find it here: Cisco-UCM-SQLi-Scripts on GitHub. Vulnerability Research & Advisories

Several repositories and Gists provide deeper insights into specific CUCM vulnerabilities and "hacking" techniques:

Cisco CUCM Hacking Gist: A technical Gist detailing commands for disabling specific services like the Smart License Manager (SLM) and preventing system registrations. View the Gist: Cisco CUCM hacking - GitHub Gist.

GitHub Security Advisories: GitHub tracks critical CUCM vulnerabilities, such as:

GHSA-3q7w-9xf2-2f3g: A high-severity vulnerability with a CVSS score of 10.0.

GHSA-4c73-jxqq-mjrg: An authenticated remote code execution vulnerability in the SOAP API endpoint. Defensive & Management Tools

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

Security research on GitHub details vulnerabilities in Cisco Unified Communications Manager (CUCM), including Remote Code Execution (CVE-2024-20253) and insecure TFTP configurations. Securing the environment requires monitoring official Cisco advisories, applying patches, and implementing hardening guides to restrict access. You can find related technical discussions and resources on GitHub.

Cisco Unified Communications Manager (CUCM) is the core of many enterprise telephony networks, making it a high-value target for security researchers and red teams. The intersection of CUCM hacking and GitHub provides a wealth of tools and documentation for identifying vulnerabilities and misconfigurations. Common Vulnerabilities and GitHub Advisories

GitHub’s Advisory Database tracks several critical vulnerabilities impacting CUCM environments, often including Proof-of-Concept (PoC) references.

Static Root Credentials (CVE-2025-20309): A critical vulnerability where unauthenticated, remote attackers can log in to affected devices using default, static root credentials that cannot be changed or deleted.

Remote Code Execution (CVE-2024-20253): Improper processing of user-provided data can allow unauthenticated attackers to execute arbitrary code with web services user privileges.

CLI Privilege Escalation: Vulnerabilities in the CUCM Command Line Interface (CLI) may allow authenticated local attackers to execute commands as the root user by bypassing command validation.

Web-Based Cross-Site Scripting (XSS): Multiple advisories, such as GHSA-34jc-mc86-8ww9 and GHSA-Fnj66YLy, document flaws in the web management interface that allow attackers to inject malicious scripts into authenticated sessions. Key Hacking and Research Tools on GitHub

Security professionals use various GitHub repositories to automate the discovery and exploitation of CUCM misconfigurations.

Cisco Unified Communications Manager (CUCM) is a frequent target for security research because it acts as the "brain" of corporate VoIP networks. Hacking and penetration testing resources for CUCM on GitHub typically focus on exploiting common misconfigurations, such as insecure TFTP servers or static credentials.

Interesting topic!

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.

A quick search on GitHub reveals some interesting projects and repositories related to CUCM hacking:

Keep in mind that hacking into CUCM systems without authorization is likely illegal and can have serious consequences. These repositories might be used for educational purposes, penetration testing, or research, but it's essential to ensure you're operating within the bounds of the law and with proper permissions.

If you're interested in learning more about CUCM security, I recommend checking out:

Would you like to know more about CUCM security or is there something specific you'd like to explore?

CUCM (formerly CallManager) runs on a hardened Linux distribution (often a variant of Red Hat). If an attacker compromises a CUCM server, they can:

Unlike traditional servers, CUCM is often overlooked by blue teams because "it’s just the phone system." That neglect is precisely what hackers exploit.

Many GitHub repositories for CUCM hacking begin with the disclaimer:

"This is for educational purposes only. Do not use on systems you do not own."

However, there is no technical enforcement. Once a cucm-root-exploit.py is public, the window to patch closes rapidly. The security community benefits from these tools because defenders can test themselves. But script kiddies also benefit.

Recommendation for defenders: Create a private fork of these repos. Run them internally as part of your Red Team arsenal. Do not leave your own GitHub stars on public exploit repos—it signals weakness.
