Description

MyBB contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the input passed to the 'url' BBCode tag upon submission. This could allow a user to create a specially crafted input that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.

Classification

Location: Remote / Network Access
Attack Type: Input Manipulation
