AI Analysis

Impact

FusionPBX includes an exposed function within the Dialplan Editor (file app/dialplans/resources/classes/dialplan.php) that does not properly sanitize user supplied input, allowing the injection and execution of arbitrary operating system commands. The flaw can be triggered remotely, giving an attacker full control over the underlying host. This can lead to complete system compromise, data loss or exfiltration, and denial of service. The weakness aligns with CWE-77 and CWE-78, indicating an input validation and execution vulnerability.

Affected Systems

Versions of FusionPBX up to and including 5.4.4, 5.5.7, and 5.6.5 are affected. Administrators should verify which build is deployed and treat those or earlier releases as at risk.

Risk and Exploitability

The CVSS score of 5.1 indicates moderate severity. No EPSS score is available, and the vulnerability is not listed in the CISA KEV catalog. Based on the description, it is inferred that the flaw can be exploited remotely, although the need for authentication is not explicitly stated. Exploit code has already been published. Given the remote nature of the attack vector, any host exposed to the network can be targeted.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the vendor's patch to upgrade FusionPBX to the latest version that addresses the command injection flaw. If an official patch is not available, upgrade to a newer FusionPBX release where the Dialplan Editor is fixed.
  • Restrict network exposure of the Dialplan Editor by configuring firewall rules or network segmentation so that only trusted administrative hosts can reach the app/dialplans/resources/classes/dialplan.php endpoint.
  • If immediate upgrade is not possible, disable the Dialplan Editor component or deny all requests to the vulnerable endpoint through configuration changes to prevent exploitation.
