![]() ![]() "This is problematic because some schemes don't contain a meaningful hostname at all, such as file:, javascript:, or data." "A more important observation was that the URL's scheme is completely ignored," Pickren noted. This method only works with websites that are currently open. Specifically, improper access is made possible by leveraging an exploit chain that stringed together multiple flaws in the way the browser parsed URL schemes and handled the security settings on a per-website basis. While third-party apps must require user's explicit consent to access the camera, Safari can access the camera or the photo gallery without any permission prompts. This makes it easy for individual websites, say Skype, to access the camera without asking for the user's permission every time the app is launched.īut there are exceptions to this rule on iOS. Safari browser grants access to certain permissions such as camera, microphone, location, and more on a per-website basis. When chained together, three of the reported Safari flaws could have allowed malicious sites to impersonate any legit site a victim trusts and access camera or microphone by abusing the permissions that were otherwise explicitly granted by the victim to the trusted domain only.Īn Exploit Chain to Abuse Safari's Per-Site Permissions "If the malicious website wanted camera access, all it had to do was masquerade as a trusted video-conferencing website such as Skype or Zoom," Pickren said. The fixes were issued in a series of updates to Safari spanning versions 13.0.5 (released January 28, 2020) and Safari 13.1 (published March 24, 2020). Turns out merely visiting a website - not just malicious but also legitimate sites unknowingly loading malicious ads as well - using Safari browser could have let remote attackers secretly access your device's camera, microphone, or location, and in some cases, saved passwords as well.Īpple recently paid a $75,000 bounty reward to an ethical hacker, Ryan Pickren, who practically demonstrated the hack and helped the company patch a total of seven new vulnerabilities before any real attacker could take advantage of them. If you use an Apple iPhone or a MacBook, we have a piece of alarming news for you.
