Last week, a "Wormable" remote code execution flaw in the Windows DNS Server service temporarily overshadowed all the other flaws patched by Microsoft on July 2020 Patch Tuesday, but CVE-2020-1147, a RCE affecting Microsoft SharePoint, was also singled out as critical and requiring a speedy fix. Implementing the offered security updates has since become even more urgent, as more exploitation details and a PoC have been released on Monday.
Cybersecurity researchers today issued a security advisory warning enterprises and governments across the globe to immediately patch a highly-critical remote code execution vulnerability affecting F5's BIG-IP networking devices running application security servers. According to Mikhail Klyuchnikov, a security researcher at Positive Technologies who discovered the flaw and reported it to F5 Networks, the issue resides in a configuration utility called Traffic Management User Interface for BIG-IP application delivery controller.
A threat actor can exploit SigRed vulnerability by sending crafted malicious DNS queries to a Windows DNS server and achieve arbitrary code execution, enabling the hacker to intercept and manipulate users' emails and network traffic, make services unavailable, harvest users' credentials and much more. Crafting Malicious DNS Responses Stating that the objective was to identify a vulnerability that would let an unauthenticated attacker compromise a Windows Domain environment, Check Point researchers said they focused on Windows DNS, specifically taking a closer look at how a DNS server parses an incoming query or a response for a forwarded query.

UPDATE. A newly discovered bug in the Zoom Client for Windows could allow remote code-execution, according to researchers at 0patch, which disclosed the existence of the flaw on Thursday after pioneering a proof-of-concept exploit for it. The company told Threatpost: "Zoom addressed this issue, which impacts users running Windows 7 and older, in the 5.1.3 client release on July 10. Users can help keep themselves secure by applying current updates or downloading the latest Zoom software with all current security updates from https://zoom.us/download.".
Microsoft has released fixes for two remote code execution vulnerabilities in the Microsoft Windows Codecs Library on Windows 10 machines. Both flaws - CVE-2020-1425 and CVE-2020-1457 - arose because of the way the Microsoft Windows Codecs Library handled objects in memory.
Drupal's security team has fixed three vulnerabilities in the popular content management system's core, one of which could be exploited to achieve remote code execution. Drupal is a free and open-source web content management system, and over a million sites run on various versions of it.
The release of a fully functional proof-of-concept exploit for a critical, wormable remote code-execution vulnerability in Windows could spark a wave of cyberattacks, the feds have warned. Microsoft patched the bug tracked as CVE-2020-0796 back in March; also known as SMBGhost or CoronaBlue, it affects Windows 10 and Windows Server 2019.
A security researcher has published a PoC RCE exploit for SMBGhost, a wormable flaw that affects SMBv3 on Windows 10 and some Windows Server versions. The PoC exploit is unreliable, but could be used by malicious attackers as a starting point for creating a more effective exploit.
Google has addressed two critical flaws in its latest monthly Android update that enable remote code execution on Android mobile devices. The critical bugs exist in the Android System area, and would allow a remote attacker using a specially crafted transmission to execute arbitrary code within the context of a privileged process.
