2-Factor Authentication Bypass Flaw Reported in cPanel and WHM Software

cPanel, a service provider of common administrative applications to handle web hosting, has patched a security vulnerability that could have allowed remote attackers with access to legitimate credentials to bypass two-factor authentication (2FA) defense on an account.

The issue, tracked as “SEC-575” and uncovered by researchers from Digital Defense, has been remedied by the company in versions 11.92..2, 11.90..17, and 11.86..32 of the program.

cPanel and WHM (Web Host Manager) provides a Linux-based mostly control panel for consumers to cope with internet site and server management, which include duties this kind of as introducing sub-domains and accomplishing method and command panel servicing. To date, around 70 million domains have been introduced on servers applying cPanel’s software package suite.

The issue stemmed from a deficiency of level-limiting during 2FA during logins, hence building it achievable for a malicious party to regularly submit 2FA codes applying a brute-pressure method and circumvent the authentication verify.

Digital Protection researchers reported an attack of this type could be accomplished in minutes.

“The two-factor authentication cPanel Security Coverage did not reduce an attacker from consistently submitting two-factor authentication codes,” cPanel mentioned in its advisory. “This authorized an attacker to bypass the two-factor authentication examine applying brute-power procedures.”

The company has now resolved the flaw by incorporating a price restrict test to its cPHulk brute-pressure security support, producing a unsuccessful validation of the 2FA code to be treated as a unsuccessful login.

This is not the very first time the absence of charge-limiting has posed a serious security problem.

Back again in July, movie conferencing application Zoom mounted a security loophole that could have allowed potential attackers to crack the numeric passcode applied to protected non-public meetings on the system and snoop on members.

It truly is suggested that cPanel shoppers use the patches to mitigate the risk affiliated with the flaw.
