VirtualBox 0-day vulnerability

VirtualBox E1000 Guest-to-Host Escape. Contribute to MorteNoir1/virtualbox_e1000_0day development by creating an account on GitHub. Vulnerable software: VirtualBox 5.2.20 and prior versions.

Host OS: any, the bug is in a shared code base. VM configuration: default (the only requirement is that a network card is Intel PRO/1000 MT Desktop (82540EM) and a mode is NAT). Until the patched VirtualBox build is out you can change the network card of your virtual machines to PCnet (either of two) or to Paravirtualized Network.

Exploit vendor drops Tor Browser zero-day on Twitter

Zerodium, a company that buys and sells vulnerabilities in popular software, has published details today on Twitter about a zero-day vulnerability in the Tor Browser, a Firefox-based browser used by privacy-conscious users for navigating the web through the anonymity provided by the Tor network. In a tweet, Zerodium said the vulnerability is a full bypass of the ‘Safest’ security level of the NoScript extension that’s included by default with all Tor Browser distributions. NoScript is a browser extension that uses a whitelist approach to let the user decide from what domains the browser can execute JavaScript, Flash, Java, or Silverlight content.

Flash zero-day exploit

Adobe is aware of a report that an exploit for CVE-2018-5002 exists in the wild, and is being used in limited, targeted attacks against Windows users. These attacks leverage Office documents with embedded malicious FlashPlayercontent distributed via email. Unlike the critical vulnerabilities patched in Adobe’sMarch, Apriland May updates, CVE-2018-5002 isn’t a remotely exploitable flaw that cybercriminals might decide to exploit in future, it’s one that we only know about because they’re exploiting it now, a so-called zero-day.

A tale of two zero-days

Late in March 2018, ESET researchers identified an interesting malicious PDF sample. A closer look revealed that the sample exploits two previously unknown vulnerabilities: a remote-code execution vulnerability in Adobe Reader and a privilege escalation vulnerability in Microsoft Windows. The use of the combined vulnerabilities is extremely powerful, as it allows an attacker to execute arbitrary code with the highest possible privileges on the vulnerable target, and with only the most minimal of user interaction.

Internet Explorer 0-Day Discovered

Microsoft has released a patch for this vulnerability, and we strongly advise to apply it, as it is just a matter of time before other threat actors start leveraging this new opportunity in spam or exploit kit campaigns. In late April, two security companies (Qihoo360 and Kaspersky) independently discovered a zero-day for Internet Explorer (CVE-2018-8174), which was used in targeted attacks for espionage purposes. This marks two years since a zero-day has been found (CVE-2016-0189 being the latest one) in the browser that won’t die, despite efforts from Microsoft to move on to the more modern Edge.

Microsoft Patches Two Zero-Day Flaws Under Active Attack

Microsoft has today released security patches for a total of 67 vulnerabilities, including two zero-days that have actively been exploited in the wild by cybercriminals, and two publicly disclosed bugs. In brief, Microsoft is addressing 21 vulnerabilities that are rated as critical, 42 rated important, and 4 rated as low severity. These patch updates address security flaws in Microsoft Windows, Internet Explorer, Microsoft Edge, Microsoft Office, Microsoft Office Exchange Server, Outlook, .NET

Root cause analysis of the latest Internet Explorer zero day – CVE-2018-8174

In late April 2018, a new zero-day vulnerability for Internet Explorer (IE) was found using our sandbox; more than two years since the last in the wild example (CVE-2016-0189). This particular vulnerability and subsequent exploit are interesting for many reasons. The following article will examine the core reasons behind the latest vulnerability, CVE-2018-8174.

Rediscovery, analysis and exploitation of a CIA zero-day MikroTik Vulnerability

This post outlines and presents the rediscovery, vulnerability analysis and exploitation of a zero-day vulnerability that was originally discovered and exploited by the CIA’s ‘Engineering Development Group’; remotely targeting MikroTik’s RouterOS embedded operating system that was discovered during the ‘Vault 7’ leak via WikiLeaks in March of 2017.

This Russian Company Sells Zero-Day Exploits for Hospital Software

In one video uploaded to Vimeo, Gleg shows an exploit being used against a hospital health information management system (HHIMS). A list of MedPack updates includes a zero-day to replace files in a piece of software from a company called MediTEX. MediTEX makes scheduling software as well as a platform for documenting therapy and quality assurance for reproductive medicine, according to the company’s website.

Life Cycle of a Web App 0 Day

Over the past few months, I’ve been monitoring the proliferation of exploits for some of my disclosed WordPress Plugin and Joomla Extension vulnerabilities against Akamai customers. I started this observation process which leads to an expected conclusion – severe vulnerabilities like SQL Injection, RFI and LFI would receive the most attention for any CMS platform. While less severe vulnerabilities such as XSS and path disclosure would likely receive less attention from the attackers.

Here’s the Letter Israel Sent to Solicit Zero-Days From American Hackers

Often, the best way to get something is to simply ask for it. That’s probably what the Israeli government thought when it sent an email to several American researchers and firms who make so-called zero-days, tools that take advantage of vulnerabilities in software that are unknown to the company that makes the software.
