Cross-site scripting (XSS) vulnerability in phpGraphy 0.9.9a and earlier allows remote attackers to inject arbitrary web script or HTML via EXIF data, such as the Camera Model Tag.

phpGraphy 0.9.11 and earlier allows remote attackers to bypass authentication and gain administrator privileges via a direct request to index.php with the editwelcome parameter set to 1, which can then be used to modify the main page to inject arbitrary HTML and web script. NOTE: XSS attacks are resultant from this issue, since normal functionality allows the admin to modify pages.
