The installation process for SOPlanning 1.32 and earlier allows remote authenticated users with a prepared database, and access to an existing database with a crafted name, or permissions to create arbitrary databases, or if PHP before 5.2 is being used, the configuration database is down, and smarty/templates_c is not writable to execute arbitrary php code via a crafted database name.
Simple Online Planning Tool version 1.32 suffers from code execution, cross site scripting, remote SQL injection, information disclosure, and path traversal vulnerabilities.
