On May 27, 2022, a Microsoft Office document was submitted from Belarus to VirusTotal, using a novel method to deliver its payload. This new technique was identified as a Zero-Day RCE (Remote Code Execution) vulnerability in Microsoft Support Diagnostic Tool (MSDT), which is now being tracked as CVE-2022-30190. As of this writing, it affects only Windows computers running with MSDT URI protocol enabled.

On Friday, May 27, 2022, Security vendor nao_sec identified a malicious document leveraging a zero-day remote code execution RCE vulnerability (CVE-2022-30190) in Microsoft Windows Support Diagnostic Tool (MSDT). The actively exploited vulnerability exists when MSDT is called using the URL protocol from a calling application, such as Microsoft Word.

This blog describes the attack path we have uncovered during a recent penetration test of a web application, coupled with a back-end infrastructure assessment. Throughout we introduce different attack techniques and tools that can be used to attack the underlying infrastructure and APIs of a web application.

Vulnerabilities in enterprise environments create many opportunities for cyber criminals to attack the organization. Bad actors may take advantage of security misconfigurations, broken authentication processes, buffer overflows, and other vulnerabilities to spread malware, launch account takeover attacks, and steal large amounts of sensitive data. As of April 2022, the U.S.

This month, Microsoft announced a vulnerability in NFS. The exploit lies in how an attacker can force a victim NFS server to request an address from the attacker’s fake NFS server. The address returned will overflow memory on the victim NFS server and cause a crash. Through Microsoft’s MAPP program, Corelight Labs reviewed a proof-of-concept exploit for this vulnerability and wrote a Zeek®-based detection for it. You can find a PCAP of this exploit in our GitHub repository.

This month, Microsoft announced a vulnerability in PPTP, a part of the VPN remote access services on Windows systems that runs on port 1723/tcp. Through Microsoft’s MAPP program, Corelight Labs reviewed a proof of concept exploit for this vulnerability and wrote a Zeek®-based detection for it.

Apple has recently released OS updates for multiple operating systems, addressing known and exploited security vulnerabilities along with previously unknown ones. During the past week, various data security organizations like the US Cybersecurity and Infrastructure Security Agency and Indian Computer Emergency Response Team have issued warnings asking users to install the latest updates on their Apple devices as soon as possible to avoid possible exploitation of devices and device data.

Snyk recently discovered overt 200 malicious packages in the npm registry. While we acknowledge that vulnerability fatigue is an issue for developers, this article is not about the typical case of typosquatting or random malicious package. This article shares the findings of targeted attacks aimed at businesses and corporations that Snyk was able to detect and share the insights.

The vulnerabilities page allows you to see all findings across your attack surface. This includes simple filters that let you specify what you want to focus on, including the level of severity, which domains you want to look at, and whether it was found in the past week or the past month.
