|inforss-rss-xss (54370)||Medium Risk|
The infoRSS extension for Firefox is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability using an RSS feed to inject malicious script into a Web page which would be executed in a victim's Web browser in the "chrome:" context, if the attacker could persuade the victim to load a specially-crafted RSS feed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
