[原文]Cross-site scripting (XSS) vulnerability in post.php in NavBoard V16 Stable(2.6.0) and V17beta2 allows remote attackers to inject arbitrary web script or HTML via the (1) b, (2) textlarge, and (3) url bbcode tags.
NavBoard contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate BBcode upon submission to the 'post.php' script. This could allow a user to create a specially crafted URL 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.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
