#34619 [NEW]: ISAPI module does not use exec/system functions correctly

From: ootoaoo at gmail dot com Operating system: Windows 2003 PHP version: 5.0.5 PHP Bug Type: IIS related Bug description: ISAPI module does not use exec/system functions correctly Description: ------------ Use IIS 6 with an ISAPI module and exec and system will never actually call the application to run. http://geesu.net/gallery2/phpinfo.php (if you want to check settings) If I use the CGI binary it works perfectly fine. Note: All other PHP things have worked fine with the ISAPI module, I only found exec and system to be broken in my tests. BUT, if the file you want to execute is in windows/system32, the program will execute and you will receive a result, otherwise you will not. Also safe_mode is off, so it's not restricting the directory. Reproduce code: --------------- // This will NOT work (assuming netstat.exe is copied to c:\tools\ $command = "c:\\tools\\netstat.exe"; echo system($command); // This will work as its in system32 $command = "netstat"; echo system($command); // This also works $command = "c:\\windows\\system32\\netstat.exe"; echo system($command); Expected result: ---------------- I expect to see the netstat result on ALL 3 Actual result: -------------- The first echo returns nothing, the last 2 return results -- Edit bug report at http://bugs.php.net/?id=34619&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34619&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34619&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34619&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34619&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34619&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34619&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34619&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34619&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34619&r=support Expected behavior: http://bugs.php.net/fix.php?id=34619&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34619&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34619&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34619&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34619&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34619&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34619&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34619&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34619&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34619&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34619&r=mysqlcfg
