vendor site: product:phpbb bug:xss risk:low A xss post has been discovered in phpbb ,the impact of this attack is very low ,because it's more a bug , than a vulnerability . An authentificated user can excute some html code in his private message box , by sending a message to an inexistant user . here's a proof of concept about this xss : - log in - get in your private message box - send a message to someone who doesn't exist with the following message : </textarea>'"><script>alert(document.cookie)</script> laurent gaffi contact: saps.audit (at) gmail (dot) com [email concealed]
