vesta 0.9.8-24 is affected by a file inclusion vulnerability in file web/add/user/index.php.

A command injection vulnerability in UploadHandler.php in Vesta Control Panel 0.9.8-24 allows remote attackers to escalate from regular registered users to root.

A directory traversal vulnerability in the v-list-user script in Vesta Control Panel 0.9.8-24 allows remote attackers to escalate from regular registered users to root via the password reset form.

VestaCP through 0.9.8-24 allows attackers to gain privileges by creating symlinks to files for which they lack permissions. After reading the RKEY value from user.conf under the /usr/local/vesta/data/users/admin directory, the admin password can be changed via a /reset/?action=confirm&user=admin&code= URI. This occurs because chmod is used unsafely.

VestaCP through 0.9.8-24 allows the admin user to escalate privileges to root because the Sudo configuration does not require a password to run /usr/local/vesta/bin scripts.
