How broadly exploitable is this vulnerability in a typical FreePBX deployment?

Exploitability depends on how widely the recordings module is exposed. In many setups, attackers need authenticated access to the web UI or related endpoints, but misconfigured or internet-exposed instances can significantly increase the reachable attack surface.

Does an attacker need valid credentials to exploit this issue?

Often, yes—recordings management is typically an authenticated feature. However, the exact requirement depends on local access control, role configuration, and any reverse proxies or additional authentication layers in front of FreePBX.

What is the safest general fix pattern for this kind of bug?

The most robust pattern is to eliminate shell-based command construction from untrusted data entirely, using safe, parameterized execution APIs or native libraries and performing strict input validation on all parameters related to recordings.
