  • HTTP GET request to /spaces/viewdefaultdecorator.action or /admin/viewdefaultdecorator.action with a decoratorName parameter containing a config file path; a 200 response body containing both 'confluence-init.properties' and 'View Default Decorator' confirms successful exploitation.
  • Shodan queries to identify exposed Atlassian Confluence instances: http.component:"Atlassian Confluence" or cpe:"cpe:2.3:a:atlassian:confluence".
  • The vulnerability is an Insecure Direct Object Reference (IDOR) allowing any authenticated user to read arbitrary configuration files by supplying file paths as the decoratorName parameter value.
  • ·Exploitation requires authentication; the attacker must be a remote authenticated user to trigger the information disclosure.
  • ·Affected versions are Confluence before 5.8.17; the vulnerability was confirmed fixed in version 5.8.17.
