Summary

FusionPBX through 5.6.5 contains an OS command injection flaw in call_recordings::download() (CWE-78). Caller ID values reach shell commands without neutralization, so an unauthenticated remote attacker can place calls with malicious caller ID values to inject commands. The commands run as the web server user once a privileged user downloads multiple recordings as a ZIP, when the record_name filename template is enabled.

Description from the CNA

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.
