    Hello :)

    Could you let us know which PHP handler (e.g. DSO, suPHP) is enabled on your system?

    Thank you.

    You may want to post to the PHPSecInfo mailing list to report this issue to them or to have them better identify specific instances where it may not be an actual security problem.

    Thank you.

    Was a user id that PHP runs as in the wheel group? If so that's not a good sign IMO, unless you were running the site under an account that you had knowingly granted that privilege to.

    Also how are you accessing phpsecinfo? Under what user or document root are you calling it? I tried it under a SuPHP user with SuEXEC and I do not get the privileged GID warning.

    I granted that permission (the wheel group thing) i call phpsecinfo like this domain.com/phpsecinfo/index.php the strange thing is the warning does not disappaer if i remove the involved user from the wheel group also i don't get a warning about the user running PHP.If it works with no warning on your end then there must be something wrong on my end i will find out i think CloudLinux (CageFS and such) have something todo with it.

    I just noticed the index.php file is just an example howto call that system jeesus sorry for being ignorant about this

    my suphp_log shows the correct UID and GID values

    hi,

    Problem solved :D after i removed the involved user from the wheel group using the usermod command it whas still saying that user is a member of the wheel group.I scratched my head and turns out CageFs has it's own group and passwd files and you need to edit them (only group file in this case) after that you need to run as root

    just posting in case anybody has the same problem.
