: A proof-of-concept (POC) exploit for a CUCM vulnerability, demonstrating how an attacker can gain unauthorized access to the system.

A critical vulnerability in the processing of specific data streams allowed remote attackers to execute arbitrary commands on the underlying operating system. GitHub quickly became populated with scripts designed to check if a system was unpatched or actively vulnerable to this flaw. Cisco CUCM hacking -- GitHub

: This remote code execution vulnerability is being actively exploited in the wild. It stems from improper input validation in HTTP requests to the web-based management interface. The proof-of-concept exploit available on GitHub demonstrates how an unauthenticated attacker can send a sequence of crafted HTTP requests to execute arbitrary commands on the underlying operating system, initially gaining user-level access and then escalating to root. The public exploit script can fetch system information (user ID, kernel version) or spawn a reverse shell. CISA has added CVE-2026-20045 to its Known Exploited Vulnerabilities catalog, underscoring the urgency for patch management. : A proof-of-concept (POC) exploit for a CUCM
