A security issue and multiple vulnerabilities have been reported in cPanel, which can be exploited by malicious, local users to disclose potentially sensitive information, bypass certain security restrictions, manipulate certain data, and gain escalated privileges and by malicious users to conduct script insertion attacks, bypass certain security restrictions, and compromise a vulnerable system.
1) The application sets insecure permissions for temporary cpmove archives during account transfer, which can be exploited to disclose private contents of another user's home directory and configuration settings.
2) An error related to creating a new Addon domain can be exploited to manipulate the httpd.conf file and subsequently e.g. cause a DoS (Denial of Service) by preventing a restart of the web server.
3) An error related to installing locale data from uploaded XML can be exploited to overwrite arbitrary system files and e.g. execute arbitrary code with root privileges.
Successful exploitation of this vulnerability requires a reseller account with the "locale-edit" ACL.
4) An error related to unsuspending user accounts can be exploited to bypass certain security restrictions and e.g. unsuspend arbitrary accounts.
Successful exploitation of this vulnerability requires a reseller account with the "(Un)Suspend" ACL.
5) Some errors exist within the cPAddons Site Software subsystem, which can be exploited to bypass certain security restrictions.
6) Certain input related to the cPAddons Site Software subsystem is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.
7) Some errors exist within the cPAddons Site Software subsystem, which can be exploited to execute arbitrary code with the privileges of any other account on the system.
8) An input sanitation error within the autorespond script can be exploited to bypass certain account restrictions.
This vulnerability is reported in versions prior to 126.96.36.199 and 188.8.131.52.
9) An error within the NVData module can be exploited to e.g. manipulate and read certain files via directory traversal sequences and subsequently change ownership and permissions of arbitrary files.
The vulnerabilities #1 through #7 and #9 are reported in versions prior to 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124, and 126.96.36.199.
Solution: Update to version 188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, or 22.214.171.124.
