info:
  name: Webmin <1.997 - Authenticated Remote Code Execution
  author: gy741
  severity: critical
  description: |
    Webmin before 1.997 is susceptible to authenticated remote code execution via software/apt-lib.pl, which lacks HTML escaping for a UI command. An attacker can perform command injection attacks and thereby execute malware, obtain sensitive information, modify data, and/or gain full control over a compromised system without entering necessary credentials.
  impact: |
    Successful exploitation of this vulnerability allows an authenticated attacker to execute arbitrary code on the target system.
  remediation: |
    Upgrade Webmin to version 1.997 or later to mitigate this vulnerability.
