  author: iamnoooob,rootxharsh,pdresearch
  severity: high
  description: |
    Pandora FMS versions <=7.0NG.722 are vulnerable to unauthenticated remote code execution by chaining an unrestricted file upload (CVE-2018-11221) and a local file inclusion (CVE-2018-11222). An attacker can upload a malicious PHP file as a plugin and execute it via LFI, leading to full compromise of the server.
  impact: |
    Unauthenticated attackers can upload malicious PHP files and execute them via local file inclusion, leading to complete server compromise and access to all managed systems.
  remediation: |
    Upgrade to Pandora FMS version 7.0NG.723 or later.
