Unrestricted file upload in the mcpuk file editor (atk/attributes/fck/editor/filemanager/browser/mcpuk/connectors/php/config.php) in Achievo 1.2.0 through 1.3.2 allows remote attackers to execute arbitrary code by uploading a file with .php followed by a safe extension, then accessing it via a direct request to the file in the Achievo root directory. NOTE: this is only a vulnerability in environments that support multiple extensions, such as Apache with the mod_mime module enabled.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
