#42729 [NEW]: $_SERVER['HTTP_X_ORIGINAL_URI'] can be overridden

From: php dot 20 dot zsh at spamgourmet dot com Operating system: * PHP version: 5.2.4 PHP Bug Type: *General Issues Bug description: $_SERVER['HTTP_X_ORIGINAL_URI'] can be overridden Description: ------------ HTTP_X_ORIGINAL_URI can be overriden by sending a X-Original-URI header. I think that shouldn't be possible... afaik it has nothing to do with request headers, since it's set even if I only provide a Host-Header. Reproduce code: --------------- X-Original-URI: javascript:alert(document.cookie) <?php echo '<a href="' . $_SERVER['HTTP_X_ORIGINAL_URI'] . '">Try again</a>'; ?> Expected result: ---------------- <a href="http://my-domain.com/script.php">Try again</a> Actual result: -------------- <a href="javascript:alert(document.cookie)">Try again</a> -- Edit bug report at http://bugs.php.net/?id=42729&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42729&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42729&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42729&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42729&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42729&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42729&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42729&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42729&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42729&r=support Expected behavior: http://bugs.php.net/fix.php?id=42729&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42729&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42729&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42729&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42729&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42729&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42729&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42729&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42729&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42729&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42729&r=mysqlcfg
