Microsoft Pays $13,000 to Hacker for Finding Authentication Flaw

Microsoft Pays $13,000 to Hacker for Finding Authentication Flaw

April 04, 2016Wang Wei
A security researcher has won $13,000 bounty from Microsoft for finding a critical flaw in its main authentication system that could allow hackers to gain access to a user's Outlook, Azure and Office accounts. The vulnerability has been uncovered by UK-based security consultant Jack Whitton and is similar to Microsoft's OAuth CSRF (Cross-Site Request Forgery) in Live.com discovered by Synack security researcher Wesley Wineberg. However, the main and only difference between the vulnerabilities is that: Flaw discovered by Wineberg affected Microsoft's OAuth protection mechanism while the one discovered by Whitton affected Microsoft's main authentication system. Microsoft handles authentication across its online services including Outlook, Azure and Office through requests made to login.live.com, login.windows.net, and login.microsoftonline.com. Now, for example, if a user browses to outlook.office.com, he/she redirects to a login.microsoftonline

A security researcher has discovered a simple but critical vulnerability in Google-owned YouTube that could be exploited by anyone to knock down the whole business of the popular video sharing website. Kamil Hismatullin , a Russian security bod, found a simple logical vulnerability that allowed him to delete any video from YouTube in one shot . While looking for Cross-Site Scripting (XSS) or Cross-Site Request Forgery (CSRF) flaws in YouTube Creator Studio, Hismatullin came across a simple logical bug that could wipe up any video by just sending an identity number of any video in a post request against any session token. The bug was simple but critical as it could be exploited by an attacker to fool YouTube easily into deleting any video on its system. "I've fought the urge to [delete] Bieber's channel," Hismatullin wrote in his blog post . "Luckily no Bieber videos were harmed." Citing the consequences of the issue, Hismatullin said "this vulne
