vBulletin Security Patch for vBulletin 4 - تحديث امني للجيل الرابع
A recent vBulletin 4 (all versions, Suite & Classic) report indicated that if an installation had been hacked previously, the attacker could hide malicious code to allow a repeated attack. To further strengthen vBulletin’s security - additional security checking and query cleaning were added to thwart such attacks.
The issue does not affect vBulletin 3.x.
To improve the security of your vBulletin 4 installation please download the patch from the members area of vBulletin: http://members.vbulletin.com/
We recommend you install this security patch as soon as possible.
The upgrade process is the same as previous patch level releases - simply download the patch from the Members' Area, extract the files and upload to your webserver, overwriting the existing files. There is no upgrade script required.
