GoDaddy plugs account hijack XSS vulnerability

Forgotten payload borks support call

Domain registrar GoDaddy has patched a blind XSS vulnerability in its customer support that could have allowed access to GoDaddy accounts.

Uber security man Matthew Bryant (@IAmMandatory) reported in a personal capacity the bug he says was located in an internal support panel.

A payload he uploaded and then forgotten had fired during a legitimate support call he placed to GoDaddy, as the officer attempted to remediate his problem.

The payload was insecurely reflected onto a support page, breaking it.

"While using GoDaddy I noticed that my first and last name could be set to an XSS payload," Bryant says.

"It was then (during the call) my phone vibrated twice indicating … notifications that my previously planted XSS payloads had fired.

"... my XSS payload borked the JSON displayed in the webpage body and escaped the script type="text/javascript block [which] caused the XSS payload to fire but broke the webpage that the support agent was viewing."

Bryant says the vulnerability meant an attacker could run any action that a GoDaddy customer rep could in what could have caused mayhem for customer accounts.

It took GoDaddy about four months to fix the hole after it brought Bryant into its private bug bounty program, and then claimed the vulnerability was a duplicate.

To make a physical comparison, blind XSS payloads act more like mines which lie dormant until someone triggers them.

Bryant says the vulnerability class is missed often in security tests.

"This flavour of XSS is often missed by penetration testers due to the standard alert box approach being a limited methodology for finding these vulnerabilities," he says. "When your payloads are all script>alert(1)</script you’re making the assumption that the XSS will fire in your browser, when it’s likely it will fire in other places and in other browsers."

Bryant recommends preventing payloads from being stored which goes beyond typical XSS remediation and affords improved security.

"When you do proper output encoding, you have to do it on every system which pulls data from your data store. However, if you simply ensure that the stored data is clean you can prevent exploitation of many systems because the payload would never be able to be stored in the first place."

The bug is one of a series the hacker will post to his blog after respective vendors have applied fixes. ®

  • US won’t prosecute ‘good faith’ security researchers under CFAA
    Well, that clears things up? Maybe not.

    The US Justice Department has directed prosecutors not to charge "good-faith security researchers" with violating the Computer Fraud and Abuse Act (CFAA) if their reasons for hacking are ethical — things like bug hunting, responsible vulnerability disclosure, or above-board penetration testing.

    Good-faith, according to the policy [PDF], means using a computer "solely for purposes of good-faith testing, investigation, and/or correction of a security flaw or vulnerability."

    Additionally, this activity must be "carried out in a manner designed to avoid any harm to individuals or the public, and where the information derived from the activity is used primarily to promote the security or safety of the class of devices, machines, or online services to which the accessed computer belongs, or those who use such devices, machines, or online services."

  • Intel plans immersion lab to chill its power-hungry chips
    AI chips are sucking down 600W+ and the solution could be to drown them.

    Intel this week unveiled a $700 million sustainability initiative to try innovative liquid and immersion cooling technologies to the datacenter.

    The project will see Intel construct a 200,000-square-foot "mega lab" approximately 20 miles west of Portland at its Hillsboro campus, where the chipmaker will qualify, test, and demo its expansive — and power hungry — datacenter portfolio using a variety of cooling tech.

    Alongside the lab, the x86 giant unveiled an open reference design for immersion cooling systems for its chips that is being developed by Intel Taiwan. The chip giant is hoping to bring other Taiwanese manufacturers into the fold and it'll then be rolled out globally.

    "This forfeiture is the largest international cybercrime recovery in the history of the Eastern District of New York," US Attorney Breon Peace said in a statement

    The action, Peace added, "sends a powerful message to those involved in cyber fraud that there are no boundaries to prosecuting these bad actors and locating their ill-gotten assets wherever they are in the world."
