info:
  name: Plesk Obsidian <=18.0.49 - Open Redirect
  author: pikpikcu
  severity: medium
  description: |
    Plesk Obsidian through 18.0.49 contains an open redirect vulnerability via the login page. An attacker can redirect users to malicious websites via a host request header and thereby access user credentials and execute unauthorized operations. NOTE: The vendor's position is "the ability to use arbitrary domain names to access the panel is an intended feature."
  remediation: |
    Upgrade Plesk Obsidian to a version higher than 18.0.49 to mitigate the vulnerability.
