TITLE:
AproxEngine Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA37158

VERIFY ADVISORY:
http://secunia.com/advisories/37158/

DESCRIPTION:
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.

SOLUTION:
Ensure that "magic_quotes_gpc" is enabled. Grant only trusted users
administrative access to the application.
