From: somemail4chuck at yahoo dot com Operating system: Linux PHP version: 5.3.0 PHP Bug Type: Output Control Bug description: Double Inserts in mysql database, double file appendage
Description: ------------ Double mysql calls or file system calls by using an image tag set to equal nothing denoted by 2 single quotes. Potential security risk as well, I have not tested for it but in theory you should be able to write the code on a form and have the server double all calls made on any page that reproduces that syntax. Reproduce code: --------------- Here is the code with explanation, about 10 lines. http://w2r.com/bugs/ Expected result: ---------------- You would expect the output to append some text to the file 1 time. Actual result: -------------- If you run this code you'll get double the data you would expect. -- Edit bug report at http://bugs.php.net/?id=48884&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48884&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48884&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48884&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48884&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48884&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48884&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48884&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48884&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48884&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48884&r=support Expected behavior: http://bugs.php.net/fix.php?id=48884&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48884&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48884&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48884&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48884&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48884&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48884&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48884&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48884&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48884&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48884&r=mysqlcfg
