Summary
Multiple Self-XSS vulnerabilities due to Template Toolkit setlist filtering.
Security Rating

Case 115833
Summary
Arbitrary code execution as root via chroothttpd.
Security Rating
cPanel has assigned a Security Level of Minor to this vulnerability.
Description
The chroothttpd script was intended to run the Apache webserver in a chroot. It functions by creating directories in a non-reserved location within the /home directory. By creating a user with the name of one of these directories, a limited privilege reseller could affect the execution of chroothttpd and execute arbitrary code as the root user. This script is outdated and non-functional on current cPanel & WHM systems. It has been removed.

Summary
Anti-XSRF tokens disclosed during session based logins.
Security Rating

Arbitrary file chown via backupadmin userbackup.
Security Rating
cPanel has assigned a Security Level of Important to this vulnerability.

cPanel includes a comprehensive protection mechanism against XSS and XSRF attacks called Security Tokens. Security Tokens protection is enabled by default in all installs of cPanel & WHM. When Security Tokens protection is enabled, an attacker intending to utilize any self-XSS vulnerabilities must convince the victim to navigate their browser to the appropriate cPanel or WHM interface and manually input the JavaScript payload.
