#27914 [NEW]: htmlentities() glitch
From: slunta at msn dot com
Operating system: Irrelevant
PHP version: Irrelevant
PHP Bug Type: Unknown/Other Function
Bug description: htmlentities() glitch
Description:
------------
There is an htmlentities glitch. If you have a message in a textarea box,
and you use </textarea>, it allows html after that to be parsed on a
message preview screen if there is one.
Reproduce code:
---------------
$input=htmlentities($input);
Expected result:
----------------
I can't really give you a code without giving out my entire message
screen, let's just say that with this textarea box I'm typing in right
now, if I decide to type in </textarea>, and then something like
<marquee>glitch</marquee>, the <marquee> would be parsed at the bottom of
the screen. My expected result is to not have this happen.
Actual result:
--------------
Of course, the actual result is allowing html after the </textarea> to be
parsed. If someone used
</textarea>
<!#cmd.execute="[database query]">
Then it would allow a db query to execute on servers if asp is mixed with
php code. This is a dangerous problem, and needs a fix. All I'm saying is
that htmlentities() needs to be allowed to block </textarea> for things
like message previews.
