TITLE:
pPIM Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA31424

VERIFY ADVISORY:
http://secunia.com/advisories/31424/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, Manipulation of data, System
access

WHERE:
>From remote

SOFTWARE:
pPIM 1.x
http://secunia.com/product/19545/

DESCRIPTION:
Some vulnerabilities have been discovered in pPIM (Phlatline's
Personal Information Manager), which can be exploited by malicious
people or users to manipulate data and compromise a vulnerable
system, and by malicious people to conduct cross-site scripting
attacks and bypass certain security restrictions.

1) Input passed to the "file" parameter in upload.php (when "mode" is
set to "delfile") is not properly sanitised before being used. This
can be exploited to delete arbitrary files via directory traversal
attacks.

Successful exploitation may require valid user credentials (but see
#3).

2) Input passed to the "date" parameter in events.php is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

Successful exploitation may require that the target user has valid
user credentials.

3) A vulnerability is caused due to improper access restriction in
changepassword.php. This can be exploited to change the password
without valid user credentials.

4) A vulnerability is caused due to missing restrictions on what file
types that users are allowed to upload in upload.php. This can be
exploited to execute arbitrary PHP code.

Successful exploitation may require valid user credentials (but see
#3).

The vulnerabilities are confirmed in version 1.01 and reported in
version 1.0. Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
Restrict access to changepassword.php and upload.php (e.g. with
".htaccess").

Use another product.
