TITLE:
PunBB SMTP Command Injection and Cross-Site Scripting

SECUNIA ADVISORY ID:
SA31219

VERIFY ADVISORY:
http://secunia.com/advisories/31219/

CRITICAL:
Less critical

IMPACT:
Security Bypass, 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 bypass certain security restrictions
or conduct cross-site scripting attacks.

1) Input passed to certain parameters in include/parser.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.

NOTE: Potential cross-site scripting vectors have also reportedly
been fixed in moderate.php.

2) An unspecified error can be exploited to inject arbitrary SMTP
commands.

The vulnerabilities affect versions prior to 1.2.19.

SOLUTION:
Update to version 1.2.19.
