vBulletin private message cross-site scripting
| vbulletin-message-xss (44576) |  Medium Risk |
Description:
vBulletin is vulnerable to cross-site scripting, caused by improper validation of user-supplied input when sending private messages. If the Show New Private Message Notification Pop-Up is enabled, a remote authenticated attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
