Multiple security flaws have been  disclosed  in VMware Workstation and Fusion products that could be exploited by threat actors to access sensitive information, trigger a denial-of-service (DoS) condition, and execute code under certain circumstances. The four vulnerabilities impact Workstation versions 17.x and Fusion versions 13.x, with fixes available in version 17.5.2 and 13.5.2, respectively, the Broadcom-owned virtualization services provider said. A brief description of each of the flaws is below - CVE-2024-22267  (CVSS score: 9.3) - A use-after-free vulnerability in the Bluetooth device that could be exploited by a malicious actor with local administrative privileges on a virtual machine to execute code as the virtual machine's VMX process running on the host CVE-2024-22268  (CVSS score: 7.1) - A heap buffer-overflow vulnerability in the Shader functionality that could be exploited by a malicious actor with non-administrative access to a virtua...

Threat actors are actively carrying out opportunistic  scanning  and  exploitation  of Exchange servers using a new exploit chain leveraging a trio of flaws affecting on-premises installations, making them the latest set of bugs after ProxyLogon vulnerabilities were exploited en masse at the start of the year. The remote code execution flaws have been collectively dubbed "ProxyShell." At least 30,000 machines are affected by the vulnerabilities,  according  to a Shodan scan performed by Jan Kopriva of SANS Internet Storm Center. "Started to see in the wild exploit attempts against our honeypot infrastructure for the Exchange ProxyShell vulnerabilities," NCC Group's Richard Warren  tweeted , noting that one of the intrusions resulted in the deployment of a "C# aspx webshell in the /aspnet_client/ directory." Patched in early March 2021,  ProxyLogon  is the moniker for CVE-2021-26855, a server-side request forgery vulnerability in Exchange ...

Google on Tuesday released a new version of Chrome web-browsing software for Windows, Mac, and Linux with patches for two newly discovered security vulnerabilities for both of which it says exploits exist in the wild, allowing attackers to engage in active exploitation. One of the two flaws concerns an insufficient validation of untrusted input in its V8 JavaScript rendering engine (CVE-2021-21220), which was demonstrated by Dataflow Security's Bruno Keith and Niklas Baumstark at the  Pwn2Own 2021  hacking contest last week. While Google moved to fix the flaw quickly, security researcher Rajvardhan Agarwal published a  working exploit  over the weekend by reverse-engineering the patch that the Chromium team pushed to the open-source component, a factor that may have played a crucial role in the release. UPDATE:   Agarwal, in an email to The Hacker News, confirmed that there's one more vulnerability affecting Chromium-based browsers that has been patched in...

An Indian security researcher has publicly published a proof-of-concept (PoC) exploit code for a newly discovered flaw impacting Google Chrome and other Chromium-based browsers like Microsoft Edge, Opera, and Brave. Released by Rajvardhan Agarwal, the working  exploit  concerns a remote code execution vulnerability in the V8 JavaScript rendering engine that powers the web browsers. It is believed to be the same flaw demonstrated by Dataflow Security's Bruno Keith and Niklas Baumstark at  Pwn2Own 2021 hacking contest  last week. Keith and Baumstark were awarded $100,000 for leveraging the vulnerability to run malicious code inside Chrome and Edge. According to the screenshot shared by Agarwal, the PoC HTML file, and its associated JavaScript file, can be loaded in a Chromium-based browser to exploit the security flaw and launch the Windows calculator (calc.exe) app. But it's worth noting that the exploit needs to be chained with another flaw that can allow it to ...

The U.S. Cybersecurity and Infrastructure Security Agency is warning of active exploitation attempts that leverage the latest line of " ProxyShell " Microsoft Exchange vulnerabilities that were patched earlier this May, including deploying LockFile ransomware on compromised systems. Tracked as CVE-2021-34473, CVE-2021-34523, and CVE-2021-31207, the vulnerabilities enable adversaries to bypass ACL controls, elevate privileges on the Exchange PowerShell backend, effectively permitting the attacker to perform unauthenticated, remote code execution. While the former two were addressed by Microsoft on April 13, a patch for CVE-2021-31207 was shipped as part of the Windows maker's May Patch Tuesday updates. "An attacker exploiting these vulnerabilities could execute arbitrary code on a vulnerable machine," CISA  said . The development comes a little over a week after cybersecurity researchers sounded the alarm on  opportunistic scanning and exploitation  of unpat...

VMware has released updates to resolve multiple security flaws impacting its Workstation and Fusion software, the most critical of which could allow a local attacker to achieve code execution. The vulnerability, tracked as CVE-2023-20869 (CVSS score: 9.3), is described as a stack-based buffer-overflow vulnerability that resides in the functionality for sharing host Bluetooth devices with the virtual machine. "A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host," the company  said . Also patched by VMware is an out-of-bounds read vulnerability affecting the same feature (CVE-2023-20870, CVSS score: 7.1), that could be abused by a local adversary with admin privileges to read sensitive information contained in hypervisor memory from a virtual machine. Both vulnerabilities were  demonstrated  by researchers from STAR Labs on the third day of the Pwn2O...

Google on Thursday released security updates to address a zero-day flaw in Chrome that it said has been actively exploited in the wild. Tracked as  CVE-2024-4671 , the high-severity vulnerability has been described as a case of use-after-free in the Visuals component. It was reported by an anonymous researcher on May 7, 2024. Use-after-free bugs , which arise when a program references a memory location after it has been deallocated, can lead to any number of consequences, ranging from a crash to arbitrary code execution. "Google is aware that an exploit for CVE-2024-4671 exists in the wild," the company  said  in a terse advisory without revealing additional specifics of how the flaw is being weaponized in real-world attacks or the identity of the threat actors behind them. With the latest development, Google has addressed two actively exploited zero-days in Chrome since the start of the year. Earlier this January, the tech g...

Hacker known as " Pinkie Pie " produced the first Chrome vulnerability at the Hack In the Box conference on Wednesday, just ahead of the deadline for the competition this afternoon. The exploit, if later confirmed by Google's US headquarters, will have earned the teenage hacker known as Pinkie Pie the top US$60,000 cash reward. In March, Pinkie Pie and Sergey Glazunov both won $60,000 for their exploits at the first Pwnium competition. Google established the Pwnium competition as an alternative to the Pwn2own contest in order to add the requirement that participants provide details of their exploit. Google will give away up to a total of US$2 million during the event. $60,000 - "Full Chrome exploit": Chrome / Win7 local OS user account persistence using only bugs in Chrome itself. $40,000 - "Partial Chrome exploit": Chrome / Win7 local OS user account persistence using at least one bug in Chrome itself, plus other bugs. For example, a WebKit bug combined with a Windows ...
