QNAP, Taiwanese maker of network-attached storage (NAS) devices, on Friday released security updates to patch nine security weaknesses, including a critical issue that could be exploited to take over an affected system. "A vulnerability has been reported to affect QNAP VS Series NVR running QVR," QNAP  said  in an advisory. "If exploited, this vulnerability allows remote attackers to run arbitrary commands." Tracked as  CVE-2022-27588  (CVSS score: 9.8), the vulnerability has been addressed in QVR 5.1.6 build 20220401 and later. Credited with reporting the flaw is the Japan Computer Emergency Response Team Coordination Center (JPCERT/CC). Aside from the critical shortcoming, QNAP has also resolved three high-severity and five medium-severity bugs in its software - CVE-2021-38693  (CVSS score: 5.3) - A  path traversal vulnerability  in thttpd affecting QNAP devices running QTS, QuTS hero, QuTScloud, and QVR Pro Appliance, leading to information disclosure C

Google has released monthly security patches for Android with fixes for 37 flaws across different components, one of which is a fix for an actively exploited Linux kernel vulnerability that came to light earlier this year. Tracked as  CVE-2021-22600  (CVSS score: 7.8), the vulnerability is ranked "High" for severity and could be exploited by a local user to escalate privileges or deny service. The issue relates to a  double-free vulnerability  residing in the  Packet  network protocol implementation in the Linux kernel that could cause memory corruption, potentially leading to denial-of-service or execution of arbitrary code. Patches were released by different Linux distributions, including  Debian ,  Red Hat ,  SUSE , and  Ubuntu  in December 2021 and January 2022. "There are indications that CVE-2021-22600 may be under limited, targeted exploitation," Google  noted  in its Android Security Bulletin for May 2022. Specifics about the nature of the attacks are

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

Cybersecurity researchers have detailed as many as five severe security flaws in the implementation of TLS protocol in several models of Aruba and Avaya network switches that could be abused to gain remote access to enterprise networks and steal valuable information. The findings follow the March disclosure of  TLStorm , a set of three critical flaws in APC Smart-UPS devices that could permit an attacker to take over control and, worse, physically damage the appliances. IoT security firm Armis, which uncovered the shortcomings, noted that the design flaws can be traced back to a common source: a misuse of  NanoSSL , a standards-based SSL developer suite from Mocana, a DigiCert subsidiary. The new set of flaws, dubbed  TLStorm 2.0 , renders Aruba and Avaya network switches vulnerable to remote code execution vulnerabilities, enabling an adversary to commandeer the devices, move laterally across the network, and exfiltrate sensitive data. Affected devices include Avaya ERS3500 Seri

According to folklore, witches were able to sail in a sieve, a strainer with holes in the bottom. Unfortunately, witches don't work in cybersecurity – where networks generally have so many vulnerabilities that they resemble sieves.  For most of us, keeping the sieve of our networks afloat requires nightmarishly hard work and frequent compromises on which holes to plug first. The reason? In 2010, just under 5000 CVEs were recorded in the MITRE vulnerabilities database. By 2021, the yearly total had skyrocketed to  over 20,000 . Today, software and network integrity are synonymous with business continuity. And this makes the issue of which vulnerabilities to address first mission-critical. Yet owing to the countless documented vulnerabilities lurking in a typical enterprise ecosystem – across thousands of laptops, servers, and internet-connected devices – less than  one in ten  actually needs to be patched. The question is: how can we know which patches will ensure that our sieve does

Microsoft on Tuesday disclosed a set of two privilege escalation vulnerabilities in the Linux operating system that could potentially allow threat actors to carry out an array of nefarious activities. Collectively called " Nimbuspwn ," the flaws "can be chained together to gain root privileges on Linux systems, allowing attackers to deploy payloads, like a root backdoor, and perform other malicious actions via arbitrary root code execution," Jonathan Bar Or of the Microsoft 365 Defender Research Team  said  in a report. On top of that, the defects — tracked as  CVE-2022-29799 and CVE-2022-29800  — could also be weaponized as a vector for root access to deploy more sophisticated threats such as ransomware. The vulnerabilities are rooted in a  systemd  component called  networkd-dispatcher , a  daemon program  for the network manager system service that's designed to dispatch network status changes. Specifically, they relate to a combination of  directory t
