PunBB "referer" and Category Name Cross-Site Scripting
Vulnerabilities

SECUNIA ADVISORY ID:
SA24843

VERIFY ADVISORY:
http://secunia.com/advisories/24843/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
PunBB 1.x
http://secunia.com/product/3700/

DESCRIPTION:
Some vulnerabilities have been reported in PunBB, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

1) Input passed to the "referer" HTTP header is not properly
sanitised before being used. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

2) The admin panel does not correctly filter the names of categories
when deleting them. This can be exploited to execute arbitrary HTML
and script code in an administrator's browser session in context of
an affected site.

Successful exploitation requires administrator privileges.

NOTE: This could further be exploited to execute arbitrary PHP code
by combining it with a file inclusion vulnerability in footer.php.

The vendor also reports several path disclosures and an "e-mail reset
annoyance". The vulnerabilities are reported in versions prior to
1.2.15.

SOLUTION:
Update to version 1.2.15.

PROVIDED AND/OR DISCOVERED BY:
DarkFig. The vendor also credits Gary13579.
