Description


Blwood has discovered a vulnerability in Nuked-Klan, which can be exploited by malicious people to conduct cross-site request forgery attacks.

The vulnerability is caused due to the application allowing blocks to be deleted via HTTP GET requests without performing any validity checks to verify the request. This can be exploited by e.g. a non-privileged user to delete arbitrary blocks via the Blocks Management by tricking an administrative user into following a specially crafted link while being authenticated.

Example:
http://[host]/index.php?file=Admin&page=block&op=del_block&bid=[block ID]

The vulnerability has been confirmed in version 1.7.6 and has also been reported in version 1.7 SP4.2. Other versions may also be affected.


Solution:
Do not browse untrusted web sites while being logged in to the administration section.
