XSS vulnerability in the Office Connector

XMLWordPrintable

      We have identified and fixed a cross-site scripting (XSS) vulnerability which may affect Confluence instances in a public environment. The XSS vulnerability is exposed in the document import function of the Confluence Office Connector.

      • An attacker might take advantage of the vulnerability to steal other users' session cookies or other credentials, by sending the credentials back to such an attacker's own web server.
      • XSS vulnerabilities potentially allow an attacker to embed their own JavaScript into a Confluence page. An attacker's text and script might be displayed to other people viewing the page. This is potentially damaging to your company's reputation.

      You can read more about XSS attacks at cgisecurity, CERT and other places on the web:
