Conditions

This is Plesk bug with ID #PPPM-8240 which is planed to be fixed in one of the future product updates.

Resolution

Login to the server via SSH and apply the following workaround:

1. Download the patched key-handler.zip file from the attachments to the server and unzip it:

   # wget https://plesk.zendesk.com/hc/article_attachments/360002982634/key-handler.zip
   # unzip key-handler.zip

2. Replace the original file with the new one at /usr/lib64/plesk-9.0/:

   # mv -i /usr/lib64/plesk-9.0/key-handler /usr/lib64/plesk-9.0/key-handler.orig
   # cp key-handler /usr/lib64/plesk-9.0/key-handler
   # chmod 750 /usr/lib64/plesk-9.0/key-handler

Note: revert the changes if it is planned to use Mod-security instead of ASL.
