Cross-site scripting (XSS) vulnerability in the parse_query_str function in include/print.php in JSBoard 2.0.10 and 2.0.11, and possibly other versions before 2.0.12, allows remote attackers to inject arbitrary web script or HTML via parameters that are set as global variables within the program, as demonstrated using the table parameter to login.php.
Directory traversal vulnerability in session.php in JSBoard 2.0.9 and earlier allows remote attackers to read arbitrary files via a .. (dot dot) in the table parameter.
