SECUNIA ADVISORY ID:
SA14394

VERIFY ADVISORY:
http://secunia.com/advisories/14394/

CRITICAL:
Moderately critical

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

WHERE:
>From remote

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

DESCRIPTION:
Some vulnerabilities have been reported in PunBB, which potentially
can be exploited by malicious users to disclose sensitive
information, and by malicious people to bypass certain security
restrictions and conduct SQL injection attacks.

1) Input passed to the "language" and "email" parameters in
"register.php", the "req_new_email" parameter in "profile.php", and
the "posts" and "topics" parameters in "moderate.php" is not properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

NOTE: Exploitation of the "req_new_email" parameter requires user
authentication and access to "moderate.php" requires user to be
moderator or administrator.

The vulnerabilities have been reported in version 1.2.1. Prior
versions may also be affected.

2) An error in "profile.php" can be exploited to disable user
accounts by setting a user's password to NULL.

The vulnerability has been reported in version 1.2.1. Prior versions
may also be affected.

3) An unspecified error in "admin_loader.php" may be exploited to
disclose the contents of arbitrary files.

SOLUTION:
Update to version 1.2.2.
