CVE-2019-1107 Root Cause Analyses for 0-day In-the-Wild Exploits - Project Zero
Posted by Maddie Stone, Project Zero
When a 0-day is exploited in the wild AND it is detected, we need to use that as an opportunity to learn as much as possible about the vulnerability and the exploit if we hope to make 0-day hard. One of the main methods to do that is to perform a root cause analysis (RCA) on the 0-day.
Our effort on this began in earnest in the last quarter of 2019. Today we are beginning to publish the root cause analyses for 0-days exploited in the wild that we have completed. While we’re publishing some in bulk now to play “catch-up”, in the future we plan to post each one in a timely manner after it’s detected and disclosed. We think publishing technical details in a timely manner is important for transparency and so that the whole of the security community can

Posted by Maddie Stone, Project Zero
In May 2019, Project Zero released our tracking spreadsheet for 0-days used “in the wild” and we started a more focused effort on analyzing and learning from these exploits. This is another way Project Zero is trying to make zero-day hard. This blog post synthesizes many of our efforts and what we’ve seen over the last year. We provide a review of what we can learn from 0-day exploits detected as used in the wild in 2019. In conjunction with this blog post, we are also publishing another blog post today about our root cause analysis work that informed the conclusions in this Year in Review. We are also releasing 8 root cause analyses that we have done for in-the-wild 0-days from 2019.

INTRODUCTION
I’m really interested in 0-days exploited in the wild and what we, the security community, can learn about them to make 0-day hard. I explained some of Project Zero’s ideas and goals around in-the-wild 0-days in a November blog post.
On December’s Patch Tuesday, I was immediately intrigued by CVE-2019-1458, a Win32k Escalation of Privilege (EoP), said to be exploited in the wild and discovered by Anton Ivanov and Alexey Kulaev of Kaspersky Lab. Later that day, Kaspersky published a blog post on the exploit. The blog post included details about the exploit, but only included partial details on the vulnerability. My end goal was to do variant analysis on the vulnerability, but without full and accurate details about the vulnerability, I n

CVE-2019-1458 [HIGH] Win32k Elevation of Privilege Vulnerability
Win32k Elevation of Privilege Vulnerability
Description: An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.
The update addresses this vulnerability by correcting how Win32k handles objects in memory.

[HIGH] Google Chrome 67, 68 and 69 Object.create exploit
Google Chrome 67, 68 and 69 Object.create exploit
This modules exploits a type confusion in Google Chromes JIT compiler. The Object.create operation can be used to cause a type confusion between a PropertyArray and a NameDictionary. The payload is executed within the rwx region of the sandboxed renderer process. This module can target the renderer process (target 0), but Google Chrome must be launched with the --no-sandbox flag for the payload to execute successfully. Alternatively, this module can use CVE-2019-1458 to escape the renderer sandbox (target 1). This will only work on vulnerable versions of Windows (e.g Windows 7) and the exploit can only be triggered once. Additionally the exploit can cause the target machine to restart when the session is terminated. A BSOD is also likely t

CVE-2019-1458 [HIGH] Microsoft Windows Uninitialized Variable Local Privilege Elevation
Microsoft Windows Uninitialized Variable Local Privilege Elevation
This module exploits CVE-2019-1458, an arbitrary pointer dereference vulnerability within win32k which occurs due to an uninitalized variable, which allows user mode attackers to write a limited amount of controlled data to an attacker controlled address in kernel memory. By utilizing this vulnerability to execute controlled writes to kernel memory, an attacker can gain arbitrary code execution as the SYSTEM user. This module has been tested against Windows 7 x64 SP1. Offsets within the exploit code may need to be adjusted to work with other versions of Windows. The exploit can only be triggered once against the target and can cause the target machine to reboot when the session is terminated.

CVE-2020-1054 [HIGH] Purple Fox EK | New CVEs, Steganography, and Virtualization Added to Attack Flow - SentinelLabs
## Executive Summary
- In recent weeks, we have seen a spike in the number of attempts to attack vulnerable versions of Internet Explorer by actors leveraging the Purple Fox exploit kit.
- Our investigations reveal that Purple Fox has iterated to include use of two recent CVEs – CVE-2020-1054 and CVE-2019-0808 – through publicly-available exploit code.
- In addition, we’ve noticed other changes to their attack flow that allow them to better circumvent firewall protections and some detection tools by adopting steganography and obscuring malicious code with code virtualization technologies.
During the last couple of years, Purple Fox has advanced its attack and delivery methods. First observed in September 2018, subsequent researchers noted that in 2019 Purple Fox dropped use of NSIS (Null

CVE-2019-1458 [HIGH] Patch Tuesday, December 2019 Edition
Microsoft today released updates to plug three dozen security holes in its Windows operating system and other software. The patches include fixes for seven critical bugs — those that can be exploited by malware or miscreants to take control over a Windows system with no help from users — as well as another flaw in most versions of Windows that is already being exploited in active attacks.
CVE-2019-1458 is what’s known as a “privilege escalation” flaw, meaning an attacker would need to previously have compromised the system using another vulnerability. Handy in that respect is CVE-2019-1468, a similarly widespread critical issue in the Windows font library that could be exploited just by getting the user to visit a hacked or malicious Web site.

The patches include fixes for seven critical bugs — those that can be exploited by malware or miscreants to take control over a Windows system with no help from users — as well as another flaw in most versions of Windows that is already being exploited in active attacks.
By nearly all accounts, the chief bugaboo this month is CVE-2019-1458 , a vulnerability in a core Windows component (Win32k) that is present in Windows 7 through 10 and Windows Server 2008-2019. This bug is already being exploited in the wild, and according to Recorded Future the exploit available for it is similar to CVE-2019-0859 , a Windows flaw reported in April that was found being sold in undergrou

CVE-2019-1468 [HIGH] December 2019 Patch Tuesday – 36 Vulns, 7 Critical, Actively Attacked Win32k vuln, Adobe vulns
This month’s Patch Tuesday is rather light and addresses 36 vulnerabilities, with only 7 labeled as Critical. Five of the seven Critical vulns are in Git for Visual Studio. The others are for Hyper-V and Win32k. Also, there is one actively attacked “Important” vuln in Win32k. Adobe released patches today covering Acrobat/Reader, ColdFusion, Photoshop, and Brackets.
## Workstation Patches
Win32k patches ( CVE-2019-1468 and CVE-2019-1458 ) should be prioritized for workstation-type devices, meaning any system that is used for email or to access the internet via a browser. This includes multi-user servers that are used as remote desktops for users.
Though listed as Important, Microsoft has disclosed that CVE-2019-1458 is actively attacked in the wild.

In November 2019, Kaspersky technologies successfully detected a Google Chrome 0-day exploit that was used in Operation WizardOpium attacks. During our investigation, we discovered that yet another 0-day exploit was used in those attacks. The exploit for Google Chrome embeds a 0-day EoP exploit (CVE-2019-1458) that is used to gain higher privileges on the infected machine as well as escaping the Chrome process sandbox.
The EoP exploit consists of two stages: a tiny PE loader and the actual exploit. After achieving a read/write primitive in the renderer process of the browser through vulnerable JS code, the PE exploit corrupts some pointers in memory to redirect code execution to the PE loader. This is done to bypass sandbox restrictions because the PE exploit canno
