Description

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

The vulnerability exists in steps/mail/func.inc due to insufficient sanitization of user-supplied data passed via crafted use of <svg><style>, as demonstrated by an onload attribute in a BODY element, within an HTML attachment. A remote attacker can trick the victim to follow a specially crafted link 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.
