[原文]Cross-site request forgery (CSRF) vulnerability in the del_block function in modules/Admin/block.php in Nuked-Klan 1.7.5 and earlier and 1.7 SP4.2 allows remote attackers to delete arbitrary "blocks" via a link with a modified bid parameter in a del_block op on the block page in index.php.
Upgrade to version 1.7.6 / 1.7 SP4.3 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
