phpAdsNew Multiple Vulnerabilities (Path Disclosure, SQL Injection)
------------------------------------------------------------------------
SUMMARY
<http://www.phpadsnew.com/>; phpAdsNew is "a banner management and
tracking system written in PHP". Multiple security vulnerabilities in
phpAdsNew allow remote attackers to disclose the true path under which the
product was installed, and to cause the program to execute arbitrary SQL
statements.
DETAILS
Vulnerable Systems:
* phpAdsNew version 2.0.6
Full Path Disclosure in create.php:
If user can access the misc/revisions/create.php, the script will echo the
whole installation path to the user:
"Starting scan at /var/www/mysite/html/ads"
If the revision script completes successfully, the user can then try to
access libraries/defaults/revisions.txt, which will then reveal all files
and their revisions and hashes, thus furthermore revealing all files that
have been manually modified by the site admin.
The revisions.txt will also reveal any file that has been added under the
installation tree, unless it's hidden (starts with '.')
Full Path Disclosures in the following files (Just by accessing with
browser):
admin/lib-updates.inc.php
admin/lib-targetstats.inc.php
admin/lib-size.inc.php
admin/lib-misc-stats.inc.php
admin/lib-hourly-hosts.inc.php
admin/lib-hourly.inc.php
admin/lib-history.inc.php
admin/graph-daily.php
SQL-injection in logout.php / lib-sessions.inc.php:
phpAdsNew doesn't properly validate the sessionID it receives from cookie
when it tries to log out the user. And it doesn't even check if the user
if really logged in in the first place, thus allowing unauthorized users
to feed data into the SQL-query that's supposed to clean the
phpads_session -table. Take into note though that this requires
magic_quotes_gpc to be off.
Impact:
A remote attacker could exploit this to learn installation paths on
server, as well as to locate new files and possible manually modified
files.
If magic_quotes_gpc is off, a remote attacker can also compromise the
integrity of the database.
