Description
FusionPBX through 5.6.5 contains an OS command injection vulnerability in call_recordings::download() that allows unauthenticated attackers to execute commands by placing calls with malicious caller ID values. When the record_name filename template is enabled, attackers can embed shell metacharacters like $(...) in the Caller-ID name or number, executing commands as the web server user once a privileged user downloads multiple recordings as a ZIP.
