New research into the inner workings of the stealthy BPFdoor malware for Linux and Solaris reveals that the threat actor behind it leveraged an old vulnerability to achieve persistence on targeted systems. Cybersecurity company CrowdStrike has observed a threat actor that focused mainly on targeting Linux and Solaris systems using the custom-built BPFDoor implant on telecommunications providers to steal personal user information.

BeyondTrust announced the release of a report which includes the latest annual breakdown of Microsoft vulnerabilities by category and product, as well as a six-year trend analysis, providing a holistic understanding of the evolving threat landscape. Microsoft groups vulnerabilities that apply to one or more of their products into the following main categories: Remote Code Execution, Elevation of Privilege, Security Feature Bypass, Tampering, Information Disclosure, Denial of Service, and Spoofing.

Cisco on Friday rolled out fixes for a medium-severity vulnerability affecting IOS XR Software that it said has been exploited in real-world attacks. Tracked as CVE-2022-20821, the issue relates to an open port vulnerability that could be abused by an unauthenticated, remote attacker to connect to a Redis instance and achieve code execution.

A critical privilege escalation flaw found in two themes used by more than 90,000 WordPress sites can allow threat actors to take over the sites completely, researchers have found. WordFence Threat Intelligence Team researcher Ramuel Gall discovered the flaw, one of five vulnerabilities he found between early April and early May in the Jupiter and JupiterX Premium WordPress themes, he revealed in a blog post published Wednesday.

A Bluetooth Low Energy vulnerability discovered by NCC Group researchers may be used by attackers to unlock Teslas, residential smart locks, building access systems, mobile phones, laptops, and many other devices. "Many products implement Bluetooth Low Energy-based proximity authentication, where the product unlocks or remains unlocked when a trusted BLE device is determined to be nearby," they explained, and added that the possibility of relay attacks against BLE proximity authentication has been known for years, but existing tools came with detectable levels of latency and were not capable of relaying connections employing link layer encryption.

The U.S. Cybersecurity and Infrastructure Security Agency on Monday added two security flaws, including the recently disclosed remote code execution bug affecting Zyxel firewalls, to its Known Exploited Vulnerabilities Catalog, citing evidence of active exploitation. Tracked as CVE-2022-30525, the vulnerability is rated 9.8 for severity and relates to a command injection flaw in select versions of the Zyxel firewall that could enable an unauthenticated adversary to execute arbitrary commands on the underlying operating system.

Zyxel has moved to address a critical security vulnerability affecting Zyxel firewall devices that enables unauthenticated and remote attackers to gain arbitrary code execution. "A command injection vulnerability in the CGI program of some firewall versions could allow an attacker to modify specific files and then execute some OS commands on a vulnerable device," the company said in an advisory published Thursday.

Threat analysts who discovered a vulnerability affecting multiple Zyxel products report that the network equipment company fixed it via a silent update pushed out two weeks ago. More specifically, security researchers at Rapid7 found the flaw, which is now tracked as CVE-2022-30525, and disclosed it to Zyxel on April 13, 2022.

The U.S. Cybersecurity and Infrastructure Security Agency has added the recently disclosed F5 BIG-IP flaw to its Known Exploited Vulnerabilities Catalog following reports of active abuse in the wild. "An attacker can use this vulnerability to do just about anything they want to on the vulnerable server," Horizon3.

A recently disclosed F5 BIG-IP vulnerability has been used in destructive attacks, attempting to erase a device's file system and make the server unusable. Last week, F5 disclosed a vulnerability tracked as CVE-2022-1388 that allows remote attackers to execute commands on BIG-IP network devices as 'root' without authentication.
