An attacker could maliciously alter a web page and if visited by a WebKit-powered browser, then unauthorised code could run on unpatched devices. Other apps that may not be browsers primarily, but have browsing features within them, also use WebKit to display web content which means the vulnerability may have a wide-reaching attack surface.

This vulnerability is the third critical WebKit bug Apple has been made to fix this year after the first two patches were released within weeks of each other at the start of the year. The second zero-day exploit patched by Apple on Wednesday is a kernel-level code execution bug that can be abused once an attacker gains an initial foothold on an affected device.

Tracked as CVE, one way an attacker could achieve that initial foothold is by exploiting the aforementioned WebKit flaw, according to researchers at Sophos. Such privileges could afford an attacker the ability to carry out activities such as spying on apps, accessing nearly all data on the device, retrieving locations, using cameras, taking screenshots, activating the microphone, and more, he said.

Like the WebKit flaw, the code required to exploit this vulnerability would have to be embedded within a maliciously crafted web page and executed after the WebKit vulnerability had already been exploited. Reduce risk and deliver greater business success with cyber-resilience capabilities. This zero-day also affects all the aforementioned iPhone and iPad devices, in addition to Macs running macOS Monterrey.

Both issues were caused by an out-of-bounds write issue and were addressed by improving the bounds checking of the vulnerable components. The two vulnerabilities patched by Apple on Wednesday represent the sixth and seventh zero-day exploits that Apple has been forced to fix this year.

The company also patched a swathe of zero-day vulnerabilities in including the ForcedEntry exploit used by the notorious Pegasus spyware developed by NSO Group.

– Apple Releases Security Updates to Patch Two New Zero-Day Vulnerabilities

 
Aug 19,  · Cyberthreat actors can leverage the zero-day exploitations to compromise these iOS devices in the healthcare sector.”. The first exploit, . Aug 18,  · Apple has fixed two zero-day vulnerabilities affecting iOS, iPadOS, and macOS Monterrey that may have been actively exploited. The first exploit is a remote code execution (RCE) flaw affecting. 2 days ago · One of the zero-days (CVE) exists in WebKit, Apple’s browser engine for Safari and for all iOS and iPadOS Web browsers. Apple described the flaw as tied to an out-of-bounds write issue.

 

Apple zero day – apple zero day

 
Or when someone is able to reverse engineer the update that fixes the vulnerability. Apple is urging macOS, iPhone and iPad users immediately to install respective updates this week that includes fixes for two zero-days under active attack. WhatsApp Downplays Damage of a Group Invite Bug WhatsApp said that claims that infiltrators can add themselves to an encrypted group chat without being noticed is incorrect. In addition, you will find them in the message confirming the subscription to the newsletter. Published Date: August 17, The patches are for vulnerabilities that allow attackers to execute arbitrary code and ultimately take over devices.

 
 

– Apple security updates fix 2 zero-days used to hack iPhones, Macs

 
 

Its goal is to make it easier to share data across separate vulnerability capabilities tools, databases, and services. These are the CVEs you need to know:. CVE : An out-of-bounds write issue was addressed with improved bounds checking. The vulnerability could allow an application to execute arbitrary code with kernel privileges.

The kernel privileges are the highest possible privileges, so an attacker could take complete control of a vulnerable system by exploiting this vulnerability.

Apple points out that they are aware of a report that this issue may have been actively exploited. Processing maliciously crafted web content may lead to arbitrary code execution. An attacker could lure a potential victim to a specially crafted website or use malvertising to compromise a vulnerable system by exploiting this vulnerability.

WebKit powers all iOS web browsers and Safari, so possible targets are iPhones, iPads, and Macs which could all be tricked into running unauthorized code. Apple doesn’t disclose, discuss, or confirm security issues until an investigation has occurred and patches or releases are available.

And even then, it depends on the anonymous researcher s that reported the vulnerabilities whether we will ever learn the technical details. Or when someone is able to reverse engineer the update that fixes the vulnerability.

That being said, it seems likely that these vulnerabilities were found in an active attack that chained the two vulnerabilities together. The attack could, for example, be done in the form of a watering hole or as part of an exploit kit. CVE could be exploited for initial code to be run. This code could be used to leverage CVE to obtain kernel privileges.
