Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The DS Ad Rotator WordPress plugin through 0.8 does not perform any capability check, nonce verification, or file-type validation on its image upload handler, allowing unauthenticated attackers to upload arbitrary files, including PHP, to a web-accessible directory, which can lead to remote code execution.
