ArticleFR suffers from multiple stored cross site scripting vulnerabilities. The issues are triggered when input passed via the POST parameter ‘name’ in Categories, POST parameters ‘title’ and ‘rel’ in Links and GET parameter ‘url’ in PingServers module is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user’s browser session in context of an affected site. Version 3.0.6 is affected.
