CVE-2024-42365Public exploitNetwork attack vector

Authenticated command execution via unsafe AMI Originate

Published Aug 8, 2024 · Updated Nov 3, 2025

Access control in Asterisk and Certified Asterisk allows remote authenticated users with AMI Originate rights to execute commands. Manager action validation permits SET with FILE or CURL and configuration reloads without SYSTEM rights, enabling writes to Asterisk configuration files and execution of an injected dialplan. The path requires an AMI account with write=originate and affects Asterisk before 18.24.2, 20.9.2, or 21.4.2 and Certified Asterisk before 18.9-cert11 or 20.7-cert2.
