Account data belonging to more than half of all Comodo Forums users has been stolen and is now traded online. The breach was possible by exploiting a vulnerability in the software that powers the forum. Comodo today published a security notice informing users that an intruder may have gained access to the forums database. “Very recently a new vulnerability in the vBulletin software, which is one of the most popular server applications for website comments including the Comodo Forums, was made public,” the notification begins.
