PHPSlash is a widely used open source Groupware utility.
PHPSlash contains a vulnerability which may disclose files readable to the webserver process on the underlying host to PHPSlash users who can 'edit' URL blocks.
Exploitation may result in attackers gaining local access to the webserver or information which could assist in further attacks.
Login as admin with GOD permissions
Access the BLOCKS admin section
(blockAdmin.php3) and
create a new block with the following information :
Title : notTrusted
Type : url
Site Location : whatever
Source URL : ./config.php3
Expire Length : 0
Owned by section : home
Data : (empty)
Order number : whatever
It will display the content of the config.php3 as text in
the block of the main page.
It might become an issue if blockAdmin.php3 gives
add/edit/remove permission to some users that are
not
supposed to access the filesystem.
