Ocean12 Membership Manager Pro is reportedly affected by a cross-site scripting vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.
An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.
