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.
