TITLE:
PHP-Post Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA22014

VERIFY ADVISORY:
http://secunia.com/advisories/22014/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, Exposure of sensitive
information

WHERE:

SOFTWARE:
PHP-Post 1.x

DESCRIPTION:
HACKERS PAL has reported some vulnerabilities in PHP-Post, which can
be exploited by malicious people to disclose sensitive information,
and conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "template" parameter in footer.php is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local resources.

Successful exploitation requires that "register_globals" is enabled
and "magic_quotes_gpc" is disabled.

2) Input passed to parameters in multiple files 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.

Examples:
http://[host]/template.php?txt_error=[code]
http://[host]/template.php?txt_templatenotexist=[code]
http://[host]/dropdown.php?txt_jumpto=[code]
http://[host]/loginline.php?txt_login=[code]

Note: Reportedly more files are affected.

3) Input passed to the "user" parameter in profile.php and to the
"table_prefix" parameter in multiple files is not properly sanitised
before being used in SQL queries. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.

Examples:
http://[host]/index.php?table_prefix=[code]
http://[host]/profile.php?table_prefix=[code]
http://[host]/header.php?msgid=w&table_prefix=[code]

Successful exploitation of the "user" parameter requires that
"magic_quotes_gpc" is disabled.

The vulnerabilities have been reported in version 1.01. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified.
