P-News 2.x
http://secunia.com/product/12774/

DESCRIPTION:
A security issue and a vulnerability have been discovered in P-News,
which can be exploited by malicious people to disclose sensitive
information and malicious users to compromise a vulnerable system.

1) The security issue is caused due to improper restrictions on
"db/user.txt", which can be exploited to disclose certain sensitive
information, e.g. usernames and MD5 hashes of passwords.

2) The profile editor does not check the file extension of uploaded
avatars. This can be exploited to execute arbitrary PHP code by
uploading a malicious PHP file as avatar.

The security issue and the vulnerability are confirmed in version
2.0. Other versions may also be affected.

SOLUTION:
Restrict access to db/user.txt and edit the source code to ensure
that file extensions are properly checked.
