TITLE:
ReVou Twitter Clone Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA33247

VERIFY ADVISORY:
http://secunia.com/advisories/33247/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, System access

WHERE:
>From remote

SOFTWARE:
ReVou Twitter Clone 2.x
http://secunia.com/advisories/product/20830/

DESCRIPTION:
Some vulnerabilities have been reported in ReVou Twitter Clone, which
can be exploited by malicious people to bypass certain security
restrictions and by malicious users to potentially compromise a
vulnerable system.

1) The "adminlogin/password.php" script improperly checks for a valid
session prior to changing passwords. This can be exploited to change
the administrator's password via a specially crafted HTTP POST
request to the affected script.

NOTE: Reportedly the vulnerability can be further exploited to
execute arbitrary PHP code by uploading a malicious PHP file.  

2) Files passed for upload to "settings/my_photo" are not properly
verified before being saved in the web root. This can be exploited to
upload arbitrary PHP files and potentially execute arbitrary PHP
code.

Successful exploitation of this vulnerability may require valid user
credentials.

SOLUTION:
Restrict access to the "settings" and "adminlogin" directories to
trusted users only.

PROVIDED AND/OR DISCOVERED BY:
1) G4N0K
2) S.W.A.T.
