Every day we discover new vulnerabilities in our systems, cracks in the fence the adversaries take advantage of to get into your organization and wreak havoc. Understanding what you have in your environment (e.g., types of devices, systems equipment, etc.) is very important in order to make sure the controls in place are working and more importantly, keeping up with the threat landscape.
The OWASP ModSecurity Core Rule Set team has reported a Denial of Service vulnerability in ModSecurity version 3.x that allows an attacker to send a crafted payload that exploits a flaw in how regular expressions are matched within the software. A CVE (CVE-2020-15598) was assigned to this vulnerability and it has been rated with a CVSSv3 score of 7.5 (high).
The recent disclosure of CVE-2020-1472 vulnerability by Microsoft showcases the need for tools that allow defenders to quickly replicate published exploit code, register attack data, and create signatures or other mitigations against released exploits with a high likelihood of exploitation against popular infrastructure or operating systems.
On September 14, CVE-2020-14386 was reported as a “high” severity threat. This CVE is a kernel security vulnerability that enables an unprivileged local process to gain root access to the system. CVE-2020-14386 is a result of a bug found in the packet socket facility in the Linux kernel. It allows a bad actor to trigger a memory corruption that can be exploited to hijack data and resources and in the most severe case, completely take over the system.
Today we released updates for a series of vulnerabilities termed ‘There’s a hole in the boot’ / BootHole in GRUB2 (GRand Unified Bootloader version 2) that could allow an attacker to subvert UEFI Secure Boot. The original vulnerability, CVE-2020-10713, which is a high priority vulnerability was alerted to Canonical in April 2020.
Links are so fundamental to web development that they're almost invisible. When we link to a third-party page, we hardly ever consider how it could become an opportunity to exploit our users. In this article, Julien Cretel introduces us to three techniques that bad actors can use to target our users and discusses how to avoid them.
With open source in our roots, we’re always excited about integrations with tools like OpenVAS, a popular open source vulnerability scanner that Greenbone Networks has maintained since 2009. If you’re not currently using OpenVAS, you can find the project here. OpenVAS contains more than 50,000 vulnerability tests with a community constantly updating its feed to adapt to the ever-evolving security landscape.
On July 14, 2020, Microsoft released a security update related to a remote code execution (RCE) and denial of service (DoS) vulnerability (CVE-2020-1350) in Windows DNS Server (2003 - 2019).
