Cisco Cucm Hacking -- Github
The attack vector involved the following steps:
Among the newer entries, CUCMber (created by bc0la) is a tool designed to automate the extraction of configuration files from Cisco phones. Inspired by TrustedSec's SeeYouCM-Thief research, CUCMber takes a list of Cisco phones and scrapes their configuration files, often revealing sensitive credentials or providing initial access to an environment. The tool addresses scalability and reliability issues present in earlier options, making it a go-to for red teams and penetration testers assessing CUCM deployments.
For authenticated attackers, SQL injection remains a potent technique. The GitHub repository Cisco-UCM-SQLi-Scripts provides scripts to exploit , an authenticated SQL injection issue in Cisco UCM. The scripts allow an attacker to enumerate all tables in the underlying Informix database and extract their contents. This vulnerability demonstrates how even a low-privileged authenticated user can escalate their access by extracting sensitive data directly from the CUCM database.
Deploying SIP manipulation scripts to test if the CUCM Dial Plan incorrectly allows unauthenticated external callers to route long-distance calls through corporate gateways. Defensive Strategies and Hardening Cisco CUCM hacking -- GitHub
Scripts like custom SIP scanners flood CUCM trunks to map valid extensions based on the server's response codes (e.g., distinguishing between 404 Not Found and 401 Unauthorized ). 2. Exploit Weaponization (CVEs)
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.
Vulnerabilities in the web-based management interface that could allow an authenticated, remote attacker to execute arbitrary commands or cause a DoS condition. SQL Injection (SQLi) The attack vector involved the following steps: Among
Although not strictly a hacking tool, the CUCM-LUA repository provides scripts that add and pass private or unknown SIP headers from a SIP trunk to end devices or other trunks. Such scripts can be abused to manipulate SIP signaling, potentially leading to call interception, fraud, or denial of service.

To protect CUCM systems from hacking attempts: For authenticated attackers, SQL injection remains a potent
GitHub hosts a variety of open-source tools designed for security assessment (and, unfortunately, malicious exploitation) of Cisco CUCM. Here are some of the most noteworthy.
: Ensure you have permission to test or exploit CUCM systems, and use these tools in accordance with applicable laws and regulations.
