Hi everyone,
phpBB Group announces the release of phpBB 2.0.16. This release addresses
some bugfixes and one critical security issue. To fix this, please apply
the following change: In viewtopic.php
Find:
$message = str_replace('"', '"',
substr(@preg_replace('#(>(((?>([^><]+|(?R)))*)<))#se',
"@preg_replace('#b(" . str_replace('\', '\\', $highlight_match) . ")b#i',
'<span style="color:#" . $theme['fontcolor3'] . ""><b>\\1</b></span>',
'\0')", '>' . $message . '<'), 1, -1)); Replace with:
$message = str_replace('"', '"',
substr(@preg_replace('#(>(((?>([^><]+|(?R)))*)<))#se',
"@preg_replace('#b(" . str_replace('\', '\\',
addslashes($highlight_match)) . ")b#i', '<span style="color:#" .
$theme['fontcolor3'] . ""><b>\\1</b></span>', '\0')", '>' . $message .
'<'), 1, -1)); If your mail program wraps the lines it is advised to get
the fix from the official announcement at:
http://www.phpbb.com/phpBB/viewtopic.php?t=302011

We urge you to update as soon as possible. You can of course find this
download available on our downloads page

available to simplify your update. The Full Package contains entire phpBB2
source and English language package. The Changed Files Only contains only
those files changed from previous versions of phpBB. Please note this
archive contains changed files for each previous release. Patch Files
contains patch compatible patches from the previous versions of phpBB.
Select whichever package is most suitable for you.
The changelog (contained within this release) is as follows:
- Fixed critical issue with highlighting - Discovered and fix provided by
Ron van Daal - Url descriptions able to be wrapped over more than one line

Does anyone know what the scope of this vulnerability actually is? "Critical
issue" isn't really enough to go on here. Are we talking arbitrary PHP code
execution or something lesser like SQL injection or slipping HTML into the
bbCode? Neither the phpBB Changelog or any advisories seem to mention what
the scope of this is. I'm guessing it's arbitrary PHP code execution based
on what previous vulnerabilities in phpBB have yielded, but it would be nice
to know for sure.

Rich.

It's highly critical. It allows one to inject PHP code.
Please see my next message, I'm releasing my advisory.

Kind regards,
