Edit report at https://bugs.php.net/bug.php?id=55497&edit=1 ID: 55497 Comment by: ian_dunn at yahoo dot com Reported by: mhaisley at gmail dot com Summary: Credits URL Security ?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 Status: Not a bug Type: Bug Package: PHP options/info functions Operating System: Any PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I agree with mhaisley, this is a security vulnerability and should be disabled by default. Many PCI compliance scanners will fail a site if it is turned on. I realize that it's not a major vulnerability, but it does give attackers information that could help them compromise a system. What are the benefits of having it enabled by default? I can't think of any significant ones. Whatever benefits there are, they'd have to outweigh the downsides, and that doesn't seem likely in this case.

Just disable it in your config file. ------------------------------------------------------------------------ [2011-08-25 03:27:29] mhaisley at gmail dot com Sorry, but it is a real issue. It should be disabled by default. ------------------------------------------------------------------------ [2011-08-25 00:19:08] johannes@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Attackers can easily brute force without knowing the version. But if youfear this makes things insecure you can set expose_php=Off in php.ini. ------------------------------------------------------------------------ [2011-08-24 02:35:55] mhaisley at gmail dot com Description: ------------ ?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 displays php credits, it also displays credits for all modules. This effectively makes it a security issue since it allows an attacker to scan for a specific vulnerable module and then exploit it. Test script: --------------- http://php.net/?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 Expected result: ---------------- ?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 should be disabled by default, or display generic information only. The current behavior is unacceptable. Actual result: -------------- Specific information regarding installed modules is displayed. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55497&edit=1
