Cross-site scripting (XSS) vulnerability in MAXdev MDPro 1.0.76 before 20060918 allows remote attackers to inject arbitrary web script or HTML via (1) vectors that bypass the XSS protection mechanisms of the pnVarCleanFromInput function, and (2) unspecified vectors related to the AntiCracker.

SQL injection vulnerability in the display function in the Topics module for MAXdev MDPro (MD-Pro) 1.0.73 and 1.0.72, and possibly other versions before 1.076, allows remote attackers to execute arbitrary SQL commands via the topicid parameter in a display action, which is not properly handled in PNuserapi.PHP.

MAXdev MDPro 1.0.73 and 1.0.72, and possibly other versions before 1.076, allows remote attackers to obtain the full path of the server via a direct request to includes/legacy.php.

MAXdev MD-Pro 1.0.73, and possibly earlier versions, allows remote attackers to obtain sensitive information via a direct request to (1) wiki.php, (2) AutoTheme directory, (3) Blocks directory, (4) admin.php, (5) pnadmin.php, or (6) Topics directory, which reveal the path in an error message.

The Downloads page in MAXdev MD-Pro 1.0.73, and possibly earlier versions, uses an incomplete blacklist to check for dangerous file extensions, which could allow remote attackers to bypass file extension checks and execute arbitrary commands by uploading a file with a different extension, as demonstrated using .inc files.
