phpGraphy before 0.9.13a does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary PHP code by uploading a config.php file via the pictures[] parameter to index.php. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in phpGraphy.

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.
