Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Cisco on Monday updated an advisory to warn customers of active exploitation of a decade-old security flaw impacting its Adaptive Security Appliance (ASA). The vulnerability, tracked as CVE-2014-2120 (CVSS score: 4.3), concerns a case of insufficient input validation in ASA's WebVPN login page that could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a targeted user of the appliance. "An attacker could exploit this vulnerability by convincing a user to access a malicious link," Cisco noted in an alert released in March 2014. As of December 2, 2024, the networking equipment major has revised its bulletin to note that it has become aware of "additional attempted exploitation" of the vulnerability in the wild. The development comes shortly after cybersecurity firm CloudSEK revealed that the threat actors behind AndroxGh0st are leveraging an extensive list of security vulnerabilities in various internet-faci...

Taiwanese networking equipment company Zyxel is warning customers of an ongoing attack targeting a "small subset" of its security products such as firewall and VPN servers. Attributing the attacks to a "sophisticated threat actor," the firm noted that the attacks single out appliances that have remote management or SSL VPN enabled, namely in the USG/ZyWALL, USG FLEX, ATP, and VPN series running on-premise ZLD firmware, implying that the targeted devices are publicly accessible over the internet. "The threat actor attempts to access a device through WAN; if successful, they then bypass authentication and establish SSL VPN tunnels with unknown user accounts, such as 'zyxel_slIvpn', 'zyxel_ts', or 'zyxel_vpn_test', to manipulate the device's configuration," Zyxel said in an  email message , which was shared on Twitter. As of writing, it's not immediately known if the attacks are exploiting previously known vulnerabilities...

A new research has demonstrated a technique that allows an attacker to bypass firewall protection and remotely access any TCP/UDP service on a victim machine. Called  NAT Slipstreaming , the method involves sending the target a link to a malicious site (or a legitimate site loaded with malicious ads) that, when visited, ultimately triggers the gateway to open any TCP/UDP port on the victim, thereby circumventing browser-based port restrictions. The findings were revealed by privacy and security researcher Samy Kamkar over the weekend. "NAT Slipstreaming exploits the user's browser in conjunction with the Application Level Gateway (ALG) connection tracking mechanism built into NATs, routers, and firewalls by chaining internal IP extraction via timing attack or WebRTC, automated remote MTU and IP fragmentation discovery, TCP packet size massaging, TURN authentication misuse, precise packet boundary control, and protocol confusion through browser abuse," Kamkar said in ...

If you're using the popular rConfig network configuration management utility to protect and manage your network devices, here we have an important and urgent warning for you. A cybersecurity researcher has recently published details and proof-of-concept exploits for two unpatched, critical remote code execution vulnerabilities in the rConfig utility, at least one of which could allow unauthenticated remote attackers to compromise targeted servers, and connected network devices. Written in native PHP, rConfig is a free, open source network device configuration management utility that allows network engineers to configure and take frequent configuration snapshots of their network devices. According to the project website, rConfig is being used to manage more than 3.3 million network devices, including switches, routers, firewalls, load-balancer, WAN optimizers. What's more worrisome? Both vulnerabilities affect all versions of rConfig, including the latest rConfig ver...

Security researchers have uncovered a new variant of the infamous Mirai Internet of Things botnet , this time targeting embedded devices intended for use within business environments in an attempt to gain control over larger bandwidth to carry out devastating DDoS attacks . Although the original creators of Mirai botnet have already been arrested and jailed , variants of the infamous IoT malware, including Satori and Okiru , keep emerging due to the availability of its source code on the Internet since 2016. First emerged in 2016, Mirai is well known IoT botnet malware that has the ability to infect routers, and security cameras, DVRs, and other smart devices—which typically use default credentials and run outdated versions of Linux—and enslaves the compromised devices to form a botnet, which is then used to conduct DDoS attacks . New Mirai Variant Targets Enterprise IoT Devices Now, Palo Alto Network Unit 42 researchers have spotted the newest variant of Mirai that...

Do you know that any app you have installed on your Android phone can monitor the network activities—even without asking for any sensitive permission—to detect when other apps on your phone are connecting to the Internet? Obviously, they cant see the content of the network traffic, but can easily find to which server you are connecting to, all without your knowledge. Knowing what apps you often use, which could be a competing or a financial app, "shady" or "malicious" app can abuse this information in various ways to breach your privacy. But it seems like Google has planned to address this serious privacy issue with the release of its next flagship mobile operating system. With Android P, any app will no longer be able to detect when other apps on your Android device are connecting to the Internet, according to the new code changes in Android Open Source Project (AOSP) first noticed by XDA Developers. "A new commit has appeared in the Android Open S...

Security researchers at Embedi have disclosed a critical vulnerability in Cisco IOS Software and Cisco IOS XE Software that could allow an unauthenticated, remote attacker to execute arbitrary code, take full control over the vulnerable network equipment and intercept traffic. The stack-based buffer overflow vulnerability (CVE-2018-0171) resides due to improper validation of packet data in Smart Install Client, a plug-and-play configuration and image-management feature that helps administrators to deploy (client) network switches easily. Embedi has published technical details and Proof-of-Concept (PoC) code after Cisco today released patch updates to address this remote code execution vulnerability, which has been given a base Common Vulnerability Scoring System (CVSS) score of 9.8 (critical). Researchers found a total of 8.5 million devices with the vulnerable port open on the Internet, leaving approximately 250,000 unpatched devices open to hackers. To exploit this vu...

Nobody likes to do router and firewall management. It often requires a lot of hard labor just keeping the infrastructure up and running. If you ever had to set up IPsec tunnels between different firewall brands, change a firewall rule and hope nothing breaks, upgrade to the latest software or urgently patch a vulnerability – you know what I am talking about. All of these issues have been with us basically forever. Recently, the list of complex tasks extended to getting cloud infrastructure connected to the rest of the network, and secure access for mobile users. There seems to be a change coming to this key part of IT, a silver lining if you will. We decided to take a look at one solution to this problem – the Cato Cloud from Cato Networks. Founded in 2015, Cato Networks provides a software-defined and cloud-based secure enterprise network that connects all locations, people and data to the Cato Cloud – a single, global, and secure network. Cato promises to simplify netwo...

Two months ago, THN reported about a similar announcement made by The American Registry for Internet Numbers (ARIN), which said that the agency is no longer able to produce IPv4 addresses in North America . Within a time frame of few months, ARIN, which handles Internet addresses in America, has announced the final exhaustion of their free pool of IPv4 addresses has reached zero... ...i.e. the availability of IPv4 (Internet Protocol version 4) addresses no more exists. Meanwhile, they are going to accept requests for IPv4, which will be approved via two ways: Wait List for Unmet IPv4 Requests - Join the waitlist for unmet requests in the hopes that a block of the desired size will be available in the future. IPv4 Transfer Market - Can be purchased from another organization that has more than it needs. So, in the future, IPv4 address space will be allocated to the approved requests on the Waiting List for Unmet Requests, if ARIN: receives any IPv4 address spac...
