Case 69513
Summary
World writable Logaholic directories allowed arbitrary code execution in varied contexts.
Security Rating
cPanel has assigned a Security Level of Important to this vulnerability.
Description
Multiple directories within /usr/local/cpanel/base/3rdparty/Logaholic were set world writable by default with permissions of 777. These directories contained, among other items, the global configuration files for the Logaholic log processing system. A local attacker could overwrite the global config file to bypass account restrictions, such as jailshell, or conduct privilege escalation attacks.

Case 74889
Summary
Security tokens were disclosed via links in WHM’s Manage SSL Hosts interface.
Security Rating
cPanel has assigned a Security Level of Minor to this vulnerability.
Description
cPanel & WHM includes cross-site request forgery tokens in all authenticated URLs. cPanel recommends that all users connect only through https to prevent the tokens from leaking to external sites via the browser’s referrer headers. It was discovered that some external links in the “Manage SSL Hosts” leaked the security token even when connected via https. This problem has been addressed by bouncing the browser through a URL with no token to cleanse the referrer.

Description
Reseller accounts that were restricted to Jailshell access, and unable to create other accounts without this restriction, could bypass this restriction by creating a custom contact program in WHM’s “Configure Customer Contact” interface. When an account owned by the reseller submitted a contact request, the custom contact program would run without the restrictions of Jailshell.

Case 76085
Summary
The translation system ACL was not being enforced properly.
Security Rating
cPanel has assigned a Security Level of Important to this vulnerability.
Description
The ability to modify translations in cPanel & WHM is restricted to reseller accounts with the “locale-edit” ACL. This ACL requirement was improperly enforced granting the virtual email accounts, owned by a reseller with this ACL, the same access as the reseller. A malicious virtual email account could misuse this vulnerability to conduct stored cross-site scripting attacks against other cPanel & WHM users by updating translations to contain malicious javascript.

Case 76789
Summary
Sensitive information was disclosed via transfer logs.
Security Rating
cPanel has assigned a Security Level of Moderate to this vulnerability.
Description
The cPanel & WHM account transfer system stores logs in the /var/cpanel/logs directory. These logs contain the details of the account transfer process including, under some error conditions, the password used to connect to the remote server. The log files created by account transfers were created with 0644 permissions, allowing local users to view any sensitive data stored there.

Case 76869
Summary
CVE-2013-6171 – Dovecot’s checkpassword authentication implementation vulnerable to response spoofing.
Security Rating
cPanel has assigned a Security Level of Important to this vulnerability.
Description
cPanel & WHM provides the Dovecot mail server by default for support of the POP3 and IMAP protocols. cPanel’s integration of Dovecot relies on the checkpassword authentication protocol to make Dovecot aware of virtual email accounts on the system. Dovecot’s implementation of this protocol uses a sensitive file descriptor passed across the executables that make up the checkpassword protocol. This allows the checkpassword-reply binary to communicate back to the dovecot-auth server if authentication is successful. A local attacker could attach to a running instance of the checkpassword-reply binary before the account information was written back to the dovecot-auth server and supply fraudulent account information. This allowed the attacker to view email and other files belonging to to the victim account.

Case 76941
Summary
Insufficient session expiration of Cpanel::LogMeIn sessions.
Security Rating
cPanel has assigned a Security Level of Minor to this vulnerability.
Description
The Cpanel::LogMeIn module is used to implement custom login screens for cPanel & WHM systems. It creates a single use session file on the cPanel system, suitable for redirecting a browser from another website. It was found that previous changes to cPanel & WHM’s session storage format for TSR 2013-0009 resulted in Cpanel::LogMeIn sessions not expiring after a single use. These sessions were instead expired according to normal session timeouts.

Case 77837
Summary
Logaholic local file inclusion vulnerability.
Security Rating
cPanel has assigned a Security Level of Important to this vulnerability.
Description
The Logaholic log processing software included with cPanel & WHM was vulnerable to a local file inclusion vulnerability through the logaholic_lang cookie. This allowed a local attacker to execute arbitrary code as the cpanel-logaholic user, potentially compromising other accounts on the system through Logaholic’s shared database.

Case 78177
Summary
There could be a local arbitrary code execution via mailman pickle files.
Security Rating
cPanel has assigned a Security Level Important of to this vulnerability.
Description
cPanel & WHM uses a single, central installation of GNU Mailman to provide mailing list functionality to all cPanel accounts. Mailman’s cgi-bin scripts are configured to be set to the GID mailman so that they can write into the Mailman list and archive directories. This resulted in the Mailman Python pickle files to have the UID ownership changed dependent on where the files were executed. A local attacker could utilize this fact to overwrite one of Mailman’s pickle files, and execute arbitrary code when the pickle file was deserialized (BugTrack ID 5257). Under some circumstances, this would allow a local attacker to execute arbitrary code as root.

Case 78253
Summary
Local arbitrary code could be executed as other accounts with mod_ruid2 enabled.
Security Rating
cPanel has assigned a Security Level of Important to this vulnerability.
Description
On systems with mod_ruid2 enabled, making any changes using the WHM “Apache mod_userdir Tweak” interface resulted in a corrupted Apache configuration. A local user could manipulate the permissions on directories and files under their control, and enable Apache to run arbitrary code with the UID and GID of a victim account via userdir URLs. Access to the “Apache mod_userdir Tweak” interface is only permitted to the root user.

Case 79133
Summary
The improper sanitization of SSL certificates could allow a local DoS of the web server.
Security Rating
cPanel has assigned a Security Level of Important to this vulnerability.
Description
cPanel user accounts with the “sslinstall” feature are allowed to install SSL certificates for the domains they control. The logic that sanitized these certificates did not account for whitespace variations in SSL certificates that Apache cannot parse. This vulnerability could be used by a malicious local attacker to make it impossible to restart the Apache web server.
