Sources and claim methodology

  • Source referencesvenbluege.de
Upstream source description

Joomla Extension - svenbluege.de - Server-side request forgery in the Google Photos picker in Event Gallery extension < 6.6.0 - The Google Photos picker of the back-end upload page fetches the thumbnails of the picked images through the server, with the OAuth access token of the Google Photos account. The task took the address to fetch from the request without checking it and asked for no form token. A prepared page on another web site could therefore make the server send the access token of the account to any address, or fetch addresses inside the server's network, in the name of a logged in administrator; a back-end user with the permission "Manage" could do the same directly. The token is valid for about an hour and reaches what the picker session of the account reaches.
