id: CVE-2023-50917

info:
  name: MajorDoMo thumb.php - OS Command Injection
  author: DhiyaneshDK
  severity: critical
  description: |
    MajorDoMo (aka Major Domestic Module) before 0662e5e allows command execution via thumb.php shell metacharacters. NOTE: this is unrelated to the Majordomo mailing-list manager.
  impact: |
    Unauthenticated attackers can execute arbitrary OS commands via shell metacharacters in the thumb.php transport parameter, potentially compromising the entire system.
  remediation: |
    Update MajorDoMo to a version newer than commit 0662e5e which addresses the command injection vulnerability.
