Atlassian Confluence Server 4.3.x < 4.3.1 XSS



The remote Confluence server is affected by a cross-site scripting (XSS) vulnerability.


Versions of Confluence 4.3.x prior to 4.3.1 contain a flaw that allows a stored XSS attack. This flaw exists because the office connector plugin does not validate input when handling the content of excel files before returning it to users. This may allow an authenticated remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.


Upgrade to Confluence 4.3.x version 4.3.1 or later.
