🌐 Cisco Unified Communications Alleged CVE-2026-20045 RCE Exploit Source Code Advertised on Underground Forum A threat actor is advertising what they claim to be source code and exploit material for CVE-2026-20045, a high-severity vulnerability affecting multiple Cisco Unified Communications products. According to the forum post, the actor claims: * Exploit targets CVE-2026-20045 * CVSS Score: 8.2 (High) * Unauthenticated Remote Code Execution (RCE) * Source code included * Exploit download available to forum members * Targets multiple Cisco Unified Communications platforms Allegedly Affected Products: * Cisco Unified Communications Manager (CUCM) * Cisco Unified CM Session Management Edition (SME) * Cisco Unified CM IM & Presence Service * Cisco Unity Connection * Cisco Webex Calling Dedicated Instance Potential Risks: * Remote code execution without authentication * Full system compromise of exposed communications infrastructure * Lateral movement into enterprise environments * Voice infrastructure disruption * Interception of communications and call management services * Persistence and privilege escalation opportunities following exploitation Analyst Note: At this stage, the forum post only claims to provide exploit source code and no technical validation has been observed. However, Cisco Unified Communications platforms are widely deployed across government, healthcare, finance, and enterprise environments. Any publicly available or privately traded RCE exploit targeting these systems would significantly increase the likelihood of opportunistic exploitation and mass scanning activity. #DDW #Intelligence #DarkWeb #Cisco
