Multiple cross-site scripting (XSS) vulnerabilities in uploader/index.php in Webbler CMS before 3.1.6 allow remote attackers to inject arbitrary web script or HTML via the (1) page or (2) login parameter.

Webbler CMS before 3.1.6 provides the full installation path within HTML comments in certain documents, which allows remote attackers to obtain sensitive information by viewing the HTML source, as demonstrated by viewing the source generated from index.php.

Webbler CMS before 3.1.6 does not properly restrict use of "mail a friend" forms, which allows remote attackers to send arbitrary amounts of forged e-mail. NOTE: this could be leveraged for spam or phishing attacks.
