4) Description of Vulnerability

Secunia Research has discovered some vulnerabilities in AproxEngine, 
which can be exploited by malicious users to manipulate certain data, 
conduct spoofing, SQL injection, and script insertion attacks and by 
malicious people to conduct SQL injection and script insertion 
attacks.

1) Input passed via the "login" parameter to index.php is not properly
sanitised before being used in an SQL query. This can be exploited to 
manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed via the "login" and "password" parameters to index.php
is not properly sanitised before being displayed to the user. This can
be exploited to insert arbitrary HTML and script code, which will be 
executed in a user's browser session in context of an affected site 
when the malicious data is being viewed.

3) Input passed via the "art" parameter to index.php is not properly 
sanitised before being used in an SQL query. This can be exploited to 
manipulate SQL queries by injecting arbitrary SQL code.

4) Input passed via the "Referer" HTTP header to index.php is not 
properly sanitised before being used in an SQL query. This can be 
exploited to manipulate SQL queries by injecting arbitrary SQL code.

5) Input passed to the "datei" parameter in /engine/inc/
galerie_unlink.php is not properly verified before being used to 
delete image files. This can be exploited to delete arbitrary files 
via directory traversal attacks.

Successful exploitation of this vulnerability requires administrative 
privileges.

6) Input passed to the "del_verz" parameter in /engine/inc/
galerie_del_verz.php is not properly verified before being used to 
delete galleries. This can be exploited to delete arbitrary 
directories via directory traversal attacks.

Successful exploitation of this vulnerability requires administrative 
privileges.

7) Input passed via the "from" parameter to index.php (when "page" is 
set to "sql_postfach" and "action" is set to "new") is not properly 
verified before being used to send mails to users. This can be 
exploited to e.g. spoof mails from the administrator.

8) Input passed via the "to", "betreff", and "elm1" parameters to 
index.php (when "page" is set to "sql_postfach" and "action" is set to 
"new") is not properly sanitised before being used in an SQL query. 
This can be exploited to manipulate SQL queries by injecting arbitrary 
SQL code.

9) Input passed via various parameters to index.php (when "page" is 
set to "sql_profil" and "action" is set to "list") is not properly 
sanitised before being used in an SQL query. This can be exploited to 
manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability on version 6.0 requires 
administrative privileges.

10) Input passed via the "generator", "author", "description", and 
"keywords" parameters to index.php (when "page" is set to 
"user_html_ed" and "action" is set to "open") is not properly 
sanitised before being used in an SQL query. This can be exploited to 
manipulate SQL queries by injecting arbitrary SQL code.

11) Input passed via the "generator", "author", "description", and 
"keywords" parameters to index.php (when "page" is set to 
"user_html_ed" and "action" is set to "open") is not properly 
sanitised before being displayed to the user. This can be exploited 
to insert arbitrary HTML and script code, which will be executed in a
user's browser session in context of an affected site when the 
malicious data is being viewed.

12) Input passed via the "mail" parameter to index.php (when "page" is 
set to "sql_profil" and "action" is set to "list") is not properly 
sanitised before being displayed to the user. This can be exploited to 
insert arbitrary HTML and script code, which will be executed in a 
user's browser session in context of an affected site when the 
malicious data is being viewed.

Successful exploitation of this vulnerability on version 6.0 requires 
administrative privileges.

13) Input passed via the "betreff" parameter to index.php (when "page" 
is set to "sql_postfach" and "action" is set to "new") is not properly 
sanitised before being displayed to the user. This can be exploited to 
insert arbitrary HTML and script code, which will be executed in a 
user's browser session in context of an affected site when the 
malicious data is being viewed.

The vulnerabilities are confirmed in versions 5.3.04 and 6.0. Other
versions may also be affected.

NOTE: Successful exploitation of all vulnerabilities except #5 and #6 
requires that "magic_quotes_gpc" is disabled.

====================================================================== 
5) Solution 

Ensure that "magic_quotes_gpc" is enabled and grant only trusted users
administrative access to the application.

======================================================================
