Problems with phpWebSite could make it possible to execute arbitrary script code in a vulnerable client.
phpWebSite does not sufficiently filter potentially malicious HTML code from news posts. As a result, when a user views a news posting that contains malicious HTML code, the code contained in the posted message would be executed in the browser of the vulnerable user. This will occur in the context of the site running the phpWebSite software.
phpWebSite is prone to cross-site scripting attacks.
This vulnerability is due to insufficient sanitization of HTML tags from URI parameters processed by the 'article.php' script. As a result, an attacker may construct a malicious link to this script which contains arbitrary HTML and script code.
When the malicious link is visited by a web user, the attacker-supplied code will be executed by their web client in the context of the site hosting the vulnerable software.
phpWebSite contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate HTML Tags upon submission to the article.php script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Upgrade to version 0.9.2 or higher, as it has been reported to fix this
vulnerability. An upgrade is required as there are no known workarounds.
