TITLE:
PHP-Nuke SQL Filter Bypass and SQL Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA24949

VERIFY ADVISORY:
http://secunia.com/advisories/24949/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Manipulation of data, Exposure of sensitive information

WHERE:
From remote

SOFTWARE:
PHP-Nuke 7.x
http://secunia.com/product/2385/

DESCRIPTION:
Aleksandar has discovered some vulnerabilities in PHP-Nuke, which can be
exploited by malicious people to conduct SQL injection attacks and to
bypass certain security restrictions.

1) The product’s SQL injection filter checks for the string “/*” but not
for the URL-encoded version “%2f%2a”. This can be exploited to bypass
the SQL injection filter.

2) Input passed to the “lid” parameter through modules.php to
modules/Web_Links/index.php (when “l_op” is set to “viewlinkcomments”,
“viewlinkeditorial”, or “ratelink”) is not properly sanitised before
being used in SQL queries. This can be exploited to manipulate SQL
queries by injecting arbitrary SQL code.

Successful exploitation allows e.g. retrieving administrator password
hashes, but requires that “magic_quotes_gpc” is disabled, and that the
attacker has knowledge of the database table prefix.

3) Input passed to the “lid” parameter through modules.php to
modules/Downloads/index.php (when “d_op” is set to
“viewdownloadeditorial”, “viewdownloadcomments”, or to
“ratedownload”) is not properly sanitised before being used in SQL
queries. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

Successful exploitation allows e.g. retrieving administrator password
hashes, but requires that “magic_quotes_gpc” is disabled, and that the
attacker has knowledge of the database table prefix.

The vulnerabilities are confirmed in version 7.9. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and that
the SQL injection filter checks for both normal and URL-encoded versions
of dangerous strings.

Set “magic_quotes_gpc” in php.ini to On.

Use another product.

TITLE:
PHP-Nuke vWar Module SQL Injection and Cross-Site Scripting

SECUNIA ADVISORY ID:
SA24887

VERIFY ADVISORY:
http://secunia.com/advisories/24887/

CRITICAL:
Moderately critical

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

WHERE:
From remote

SOFTWARE:
vWar 1.x (module for PHP-Nuke) http://secunia.com/product/13959/

DESCRIPTION:
Janek Vind has discovered some vulnerabilities in the vWar module for
PHP-Nuke, which can be exploited by malicious people to conduct SQL
injection attacks and cross-site scripting attacks.

1) Input passed to the “n” parameter in extra/online.php is not properly
sanitised before being used in SQL queries. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation allows e.g. retrieving administrator usernames,
password hashes, and e-mail addresses, but requires knowledge of vWar’s
database table prefix.

2) Input passed to the “title” parameter in extra/today.php (when
“whattoshow” is set to “3″) is not properly sanitised before being
returned to a user. This can be exploited to execute arbitrary HTML and
script code in a user’s browser session in context of an affected site.

3) Input passed to the “memberlist” parameter in extra/login.php is not
properly sanitised before being returned to a 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 of this vulnerability requires that the target
user is not logged in.

The vulnerabilities are confirmed in version 1.5 R15. Other versions may
also be affected.

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