function t3lib_div::validPathStr fails on certain file names
Added by Jürgen Tauschl almost 13 years ago.
Updated about 6 years ago.
Description
File t3lib/class.t3lib_div.php Line 3952 (function validPathStr):
if (strpos($theFile, '//') === FALSE && strpos($theFile, '\\') === FALSE && !preg_match('#(?:^\.\.|/\.\./|[[:cntrl:]])#', $theFile)) {
return TRUE;
}
The [[:cntrl:]] part of the search pattern matches on certain German umlauts (Ü, ß). The result is that certain files won't be shown.
Problem exists also in 4.5(.6).

It also fails on any cyrillic letters. Thus it is not possible to have UTF-8 file names from t3lib_div::getFileGetAbsFileName().

What are the exact letter that match the query?
I tried this:
$theFile='asdasäöüÄÖÜßАБВГДЕЖЅЗИІКЛМНОПҀРСТѸФХѠЦЧШЩЪꙐЬѢꙖѤЮѦѪѨѬѮѰѲѴ';
var_dump(preg_match('#(?:^\.\.|/\.\./|[[:cntrl:]])#', $theFile));
But the result is "int 0"
Maybe it depends on the PHP version or if zend multibyte is used?
Maybe adding the "u" modifier already helps on your side?
$theFile='asdasäöüÄÖÜßАБВГДЕЖЅЗИІКЛМНОПҀРСТѸФХѠЦЧШЩЪꙐЬѢꙖѤЮѦѪѨѬѮѰѲѴ';
var_dump(preg_match('#(?:^\.\.|/\.\./|[[:cntrl:]])#u', $theFile));
I attached a test file. Please, put it into the root of any TYPO3 installation and run. The result will be:
t3lib_div::validPathStr('fileadmin/templates/Ссылки (fce).xml') returns false
Expected result is:
t3lib_div::validPathStr('fileadmin/templates/Ссылки (fce).xml') returns true
