Description:
------------
In more detail, OS:
Linux 2.6.32-32-server x86_64 #62-Ubuntu SMP Wed Apr 20 22:07:43 UTC 2011
PHP 5.3.2-1ubuntu4.9 with Suhosin-Patch (cli) (built: May 3 2011 00:45:52)
This is the standard PHP package from Ubuntu Lucid's "main" repo. I did not
compile it. I have enabled the trans-
sid option.
When generating a long list of links, occasionally the trans-sid function will
miss the end of the "href"
attribute and add "?PHPSESSID=73...07" outside the closing double quote mark.
eg:
<td><a href="index.php?
area=gallery&page=edit_photo&file=gallery_36.jpg&PHPSESSID=73...07"><img
src="images/edit.png" />gallery_36.jpg</a></td>
...
<td><a href="index.php?area=gallery&page=edit_photo&file=gallery_37.jpg"?
PHPSESSID=73...07><img
src="images/edit.png" />gallery_37.jpg</a></td>
Note that since it is outside the quote mark, it is generated with a "?" instead
of "&". This reliably
happens on the "gallery_37.jpg" link, and the "gallery_18.jpg" link, and a few
others.
Test script:
---------------
The relevant loop:
while ($row = mysql_fetch_assoc($result)) {
$file = sanitise_html($row["filename"]);
$title = sanitise_html($row["title"]);
?>
<tr>
<td><a href="index.php?area=gallery&page=edit_photo&file=<?=$file?>"><img src="images/edit.png" /><?=$file?></a></td>
<td><?=$title?></td>
<td><a href="index.php?area=gallery&page=delete_photo&file=<?=$file?>"><img src="images/delete.png" /></a></td>
</tr>
<?
}
Expected result:
----------------
In the example above, I would expect:
&PHPSESSID=73...07
to be added to the end of every link, in the proper place, *inside* the end of the
href attribute.
Actual result:
--------------
On some links, the PHPSESSID appears *outside* the end of the href attribute. This
causes the PHPSESSID not to be included in the link.

Was able to reproduce on different installations on 5.3.6 and 5.3.5. If I place link before broken one, then this new one becomes broken. Unfortunately can't test in other versions due to complication installation. Relevant part HTML (5th link is broken, but there are links before that HTML): ... <a href="a?PHPSESSID=c5e10c3bb9d776c7b618531d31bb44ae"> abcdefghijkjlmopqrstuvwxyz </a> <a href="b?PHPSESSID=c5e10c3bb9d776c7b618531d31bb44ae"> abcdefghijkjlmopqrstuvwxyz </a> <a href="c?PHPSESSID=c5e10c3bb9d776c7b618531d31bb44ae"> abcdefghijkjlmopqrstuvwxyz </a> <a href="d?PHPSESSID=c5e10c3bb9d776c7b618531d31bb44ae"> abcdefghijkjlmopqrstuvwxyz </a> <a href="e"?PHPSESSID=c5e10c3bb9d776c7b618531d31bb44ae> abcdefghijkjlmopqrstuvwxyz </a> <a href="f?PHPSESSID=c5e10c3bb9d776c7b618531d31bb44ae"> abcdefghijkjlmopqrstuvwxyz </a> ... -------------- Relevant code: // add start if (strpos($url_item, 'translation') !== false) { // to make it around 17th link on page ?> <a href="<?= "a" ?>"> abcdefghijkjlmopqrstuvwxyz </a> <a href="<?= "b" ?>"> abcdefghijkjlmopqrstuvwxyz </a> <a href="<?= "c" ?>"> abcdefghijkjlmopqrstuvwxyz </a> <a href="<?= "d" ?>"> abcdefghijkjlmopqrstuvwxyz </a> <a href="<?= "e" ?>"> abcdefghijkjlmopqrstuvwxyz </a> <a href="<?= "f" ?>"> abcdefghijkjlmopqrstuvwxyz </a> <?php } // add end ----
