Facebook Patches Bug that Exposed Private Information
Facebook recently addressed a vulnerability that could have allowed anyone to access private information about users and their contacts.
The vulnerability, Imperva security researcher Ron Masas explains, was found in Facebook's online search function. He discovered that the HTML code for every search result contained an iframe element that could be exploited maliciously.
The issue is that the endpoint that expects a GET request with a number of search parameters is now cross-site request forgery (CSRF) protected. This allow users to share the search results page via a URL, but most users won't take action, which makes it a non-issue.
When it comes to the Facebook online search, however, the problem is that the CSRF bug can be combined with the fact that iframes are exposed in part to cross-origin documents.
The user interaction triggers a popup or a new tab to the Facebook search page, and the attacker forces the user to execute any search query they want.
"Since the number of iframe elements on the page reflects the number of search results, we can simply count them by accessing the fb.frames.length property. By manipulating Facebook's graph search, it's possible to craft search queries that reflect personal information about the user," Masas explains.
The security researcher, who published a proof-of-concept video, notes that he was able to extract a variety of private user data by exploiting the issue.
Such information included details on whether the user had friends from Israel or friends named "Ron," whether the user had taken photos in certain locations/countries, if they had Islamic friends or Islamic friends living in the UK, and even if the user or their friends wrote a post containing a specific text.
The process, the researcher explains, can be repeated without the need for a new popup or tab, as the attacker has control over the location property of the Facebook window through running a specific snippet of code.
"This is especially dangerous for mobile users, since the open tab can easily get lost in the background, allowing the attacker to extract the results for multiple queries, while the user is watching a video or reading an article on the attacker's site," the security researcher says.
The attacker doesn't even need a Facebook account to extract said information, Imperva told SecurityWeek in an email. The security firm also said that Facebook, who was alerted on the bug in May, issued two bounties (mobile and desktop), for the total amount of $8,000.

After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic
Lenovo is announcing a pair of new laptops today, the Yoga 730 and Flex 14, both of which are seeing a number of small design tweaks and receiving Intel’s 8th gen processors. While there aren’t any major changes this year, the 730 is getting one notable improvement to help it stand out: it has built-in far-field mics so that it can support Alexa. The Yoga 730 is really similar to last year’s Yoga 720 : like all Yoga laptops, it has a touchscreen and can flip around into tablet mode; it starts with a price around $900 but can go much higher if you spec it out; and while it’s a well-made laptop with an aluminum body, it isn’t quite as slim or light as what Lenovo offers in its Yoga 900 series laptops. This year, the 730 has received a few... Continue reading… via The Verge - Tech Posts "http://ift.tt/2BQTs1c"
