CVE-ID: CVE-2017-9305

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in tiki-batch_send_newsletter.php (vulnerable code resides within lib/core/TikiFilter/PreventXss.php). A remote attacker can trick the victim to follow a specially crafted link, bypass implemented XSS protection and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
