Directory traversal vulnerability in cmsimple/cms.php in CMSimple 3.1, when register_globals is enabled, allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the sl parameter to index.php. NOTE: this can be leveraged for remote file execution by including adm.php and then invoking the upload action. NOTE: on 20080601, the vendor patched 3.1 without changing the version number.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
