A previously undisclosed vulnerability in the web hosting control panel cPanel as well as the company's WebHost Manager (WHM) has been discovered by the vulnerability and threat management firm Digital Defense.

cPanel and WHM are a suite of Linux tools that allow hosting providers and their customers to automate server management and other web hosting related tasks. cPanel has served the global hosting community for more than 20 years and over 70m domains have been launched using its software.

The vulnerability, discovered by Digital Defense which affects cPanel and WHM version 11.90.05 (90.0 Build 5), is a two-factor authentication bypass flaw that can be exploited by brute force attacks. As a result, an attacker with knowledge of or access to valid credentials could bypass two-factor authentication protections on a user's cPanel or WHM account.

CPanel provided further details on the vulnerability in a recent security advisory, saying:

“The two-factor authentication cPanel Security Policy did not prevent an attacker from repeatedly submitting two-factor authentication codes. This allowed an attacker to bypass the two-factor authentication check using brute force techniques. Failed validation of the two-factor authentication code is now treated as equivalent to a failure of the account’s primary password validation and rate limited by cPHulk.”
