phpMyAdmin <4.8.5 - Local File Inclusion

id: CVE-2019-6799

info:
  name: phpMyAdmin <4.8.5 - Local File Inclusion
  author: pwnhxl
  severity: medium
  description: |
    phpMyAdmin before 4.8.5 is susceptible to local file inclusion. When the AllowArbitraryServer configuration setting is set to true, an attacker can read, with the use of a rogue MySQL server, any file on the server that the web server's user can access. This is related to the mysql.allow_local_infile PHP configuration, and the inadvertent ignoring of options(MYSQLI_OPT_LOCAL_INFIL calls.
  impact: |
    Successful exploitation of this vulnerability can lead to unauthorized access to sensitive files.
  remediation: |
    Upgrade phpMyAdmin to version 4.8.5 or later to mitigate this vulnerability.
