This novel zero-day vulnerability was discovered as well as privately reported past times application safety engineer Brett Buerhaus to Google on September 1 as well as the society fixed the flaw inside 17 days. In central for the report, Google paid the researcher $5,000 every bit a vantage nether its põrnikas bounty program.
According to the researcher, when users access a service that hasn’t been configured for their domain, they are presented amongst a "ServiceNotAllowed" page. This page allows users to switch betwixt accounts inwards gild to log inwards to the service.

This allowed y'all to arts and crafts Cross-Site Scripting attacks past times using "javascript:" every bit business office of the URL as well as it would execute when the browser place is redirected."
Patching the vulnerability on the 17th solar daytime afterward reported to the society shows the search engine giant’s concern to secure its software as well as users every bit well.
However, the recent vulnerability troubles visited Microsoft exposed one-after-one 3 serious zero-day vulnerabilities inwards Windows seven as well as 8.1 operating systems, reported past times Google’s Project Zero team. Microsoft wasn't able to ready the safety flaws inwards its software fifty-fifty afterward a three-month-long fourth dimension catamenia provided to the company.
