If you're using AWS, it's easy to assume your cloud security is handled - but that's a dangerous misconception. AWS secures its own infrastructure, but security within a cloud environment remains the customer's responsibility. Think of AWS security like protecting a building: AWS provides strong walls and a solid roof, but it's up to the customer to handle the locks, install the alarm systems, and ensure valuables aren't left exposed. In this blog, we'll clarify what AWS doesn't secure, highlight real-world vulnerabilities, and how cloud security scanners like Intruder can help. Understanding the AWS Shared Responsibility Model AWS operates on a Shared Responsibility Model . In simple terms: AWS is responsible for securing the underlying infrastructure (e.g., hardware, networking, data centers) - the "walls and roof." The customer is responsible for securing their data, applications, and configurations within AWS - the "locks and al...

An exhaustive evaluation of three firewall models from Palo Alto Networks has uncovered a host of known security flaws impacting the devices' firmware as well as misconfigured security features. "These weren't obscure, corner-case vulnerabilities," security vendor Eclypsium said in a report shared with The Hacker News. "Instead these were very well-known issues that we wouldn't expect to see even on a consumer-grade laptop. These issues could allow attackers to evade even the most basic integrity protections, such as Secure Boot, and modify device firmware if exploited." The company said it analyzed three firewall appliances from Palo Alto Networks, PA-3260, PA-1410, and PA-415, the first of which officially reached end-of-sale on August 31, 2023. The other two models are fully supported firewall platforms. The list of identified flaws, collectively named PANdora's Box , is as follows - CVE-2020-10713 aka BootHole (Affects PA-3260, PA-14...

Threat actors are attempting to take advantage of a recently disclosed security flaw impacting GFI KerioControl firewalls that, if successfully exploited, could allow malicious actors to achieve remote code execution (RCE). The vulnerability in question, CVE-2024-52875 , refers to a carriage return line feed ( CRLF ) injection attack, paving the way for HTTP response splitting , which could then lead to a cross-site scripting (XSS) flaw. Successful exploitation of the 1-click RCE flaw permits an attacker to inject malicious inputs into HTTP response headers by introducing carriage return (\r) and line feed (\n) characters.  The flaw impacts KerioControl versions 9.2.5 through 9.4.5, according to security researcher Egidio Romano, who discovered and reported the flaw in early November 2024. The HTTP response splitting flaws have been uncovered in the following URI paths - /nonauth/addCertException.cs /nonauth/guestConfirm.cs /nonauth/expiration.cs "User input passed ...

Two critical security flaws impacting the Spam protection, Anti-Spam, and FireWall plugin for WordPress could allow an unauthenticated attacker to install and enable malicious plugins on susceptible sites and potentially achieve remote code execution. The vulnerabilities, tracked as CVE-2024-10542 and CVE-2024-10781 , carry a CVSS score of 9.8 out of a maximum of 10.0. They were addressed in versions 6.44 and 6.45 released this month. Installed on over 200,000 WordPress sites, CleanTalk's Spam protection,f Anti-Spam, FireWall plugin is advertised as a "universal anti-spam plugin" that blocks spam comments, registrations, surveys, and more. According to Wordfence, both vulnerabilities concern an authorization bypass issue that could allow a malicious actor to install and activate arbitrary plugins. This could then pave the way for remote code execution if the activated plugin is vulnerable of its own. The plugin is "vulnerable to unauthorized Arbitrary Plugin ...

Palo Alto Networks has released new indicators of compromise (IoCs) a day after the network security vendor confirmed that a zero-day vulnerability impacting its PAN-OS firewall management interface has been actively exploited in the wild. To that end, the company said it observed malicious activity originating from below IP addresses and targeting PAN-OS management web interface IP addresses that are accessible over the internet - 136.144.17[.]* 173.239.218[.]251 216.73.162[.]* The company, however, warned that these IP addresses may possibly represent "third-party VPNs with legitimate user activity originating from these IPs to other destinations." Palo Alto Networks' updated advisory indicates that the flaw is being exploited to deploy a web shell on compromised devices, allowing threat actors to gain persistent remote access. The vulnerability, which is yet to be assigned a CVE identifier, carries a CVSS score of 9.3, indicating critical severity. It allow...

Cisco on Wednesday said it has released updates to address an actively exploited security flaw in its Adaptive Security Appliance (ASA) that could lead to a denial-of-service (DoS) condition. The vulnerability, tracked as CVE-2024-20481 (CVSS score: 5.8), affects the Remote Access VPN (RAVPN) service of Cisco ASA and Cisco Firepower Threat Defense (FTD) Software. Arising due to resource exhaustion, the security flaw could be exploited by unauthenticated, remote attackers to cause a DoS of the RAVPN service. "An attacker could exploit this vulnerability by sending a large number of VPN authentication requests to an affected device," Cisco said in an advisory. "A successful exploit could allow the attacker to exhaust resources, resulting in a DoS of the RAVPN service on the affected device." Restoration of the RAVPN service may require a reload of the device depending on the impact of the attack, the networking equipment company added. While there are no dire...

SonicWall has revealed that a recently patched critical security flaw impacting SonicOS may have come under active exploitation, making it essential that users apply the patches as soon as possible. The vulnerability, tracked as CVE-2024-40766, carries a CVSS score of 9.3 out of a maximum of 10. "An improper access control vulnerability has been identified in the SonicWall SonicOS management access and SSLVPN, potentially leading to unauthorized resource access and in specific conditions, causing the firewall to crash," SonicWall said in an updated advisory. With the latest development, the company has revealed that CVE-2024-40766 also impacts the firewall's SSLVPN feature. The issue has been addressed in the below versions - SOHO (Gen 5 Firewalls) - 5.9.2.14-13o Gen 6 Firewalls - 6.5.2.8-2n (for SM9800, NSsp 12400, and NSsp 12800) and 6.5.4.15.116n (for other Gen 6 Firewall appliances) The network security vendor has since updated the bulletin to reflect the p...

Microsoft is warning about the potential abuse of Azure Service Tags by malicious actors to forge requests from a trusted service and get around firewall rules, thereby allowing them to gain unauthorized access to cloud resources. "This case does highlight an inherent risk in using service tags as a single mechanism for vetting incoming network traffic," the Microsoft Security Response Center (MSRC) said in a guidance issued last week. "Service tags are not to be treated as a security boundary and should only be used as a routing mechanism in conjunction with validation controls. Service tags are not a comprehensive way to secure traffic to a customer's origin and do not replace input validation to prevent vulnerabilities that may be associated with web requests." The statement comes in response to findings from cybersecurity firm Tenable, which found that Azure customers whose firewall rules rely on Azure Service Tags could be bypassed. There is no evidence t...

The threat actors behind the RedTail cryptocurrency mining malware have added a recently disclosed security flaw impacting Palo Alto Networks firewalls to its exploit arsenal. The addition of the PAN-OS vulnerability to its toolkit has been complemented by updates to the malware, which now incorporates new anti-analysis techniques, according to findings from web infrastructure and security company Akamai. "The attackers have taken a step forward by employing private crypto-mining pools for greater control over mining outcomes despite the increased operational and financial costs," security researchers Ryan Barnett, Stiv Kupchik, and Maxim Zavodchik said in a technical report shared with The Hacker News. The infection sequence discovered by Akamai exploits a now-patched vulnerability in PAN-OS tracked as CVE-2024-3400 (CVSS score: 10.0) that could allow an unauthenticated attacker to execute arbitrary code with root privileges on the firewall. A successful exploitatio...

Researchers have detailed a Virtual Private Network (VPN) bypass technique dubbed  TunnelVision  that allows threat actors to snoop on victim's network traffic by just being on the same local network. The "decloaking"  method  has been assigned the CVE identifier  CVE-2024-3661  (CVSS score: 7.6). It impacts all operating systems that implement a DHCP client and has support for DHCP option 121 routes. At its core, TunnelVision involves the routing of traffic without encryption through a VPN by means of an attacker-configured DHCP server using the  classless static route option 121  to set a route on the VPN user's  routing table . It also stems from the fact the DHCP protocol, by design, does not authenticate such option messages, thus exposing them to manipulation. DHCP is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as ...

Two security vulnerabilities have been discovered in F5 Next Central Manager that could be exploited by a threat actor to seize control of the devices and create hidden rogue administrator accounts for persistence. The remotely exploitable flaws "can give attackers full administrative control of the device, and subsequently allow attackers to create accounts on any F5 assets managed by the Next Central Manager," security firm Eclypsium  said  in a new report. A description of the two issues is as follows - CVE-2024-21793  (CVSS score: 7.5) - An OData injection vulnerability that could allow an unauthenticated attacker to execute malicious SQL statements through the BIG-IP NEXT Central Manager API CVE-2024-26026  (CVSS score: 7.5) - An SQL injection vulnerability that could allow an unauthenticated attacker to execute malicious SQL statements through the BIG-IP Next Central Manager API Both the flaws impact Next Central Manager versions from 20.0.1...

A previously undocumented cyber threat dubbed  Muddling Meerkat  has been observed undertaking sophisticated domain name system (DNS) activities in a likely effort to evade security measures and conduct reconnaissance of networks across the world since October 2019. Cloud security firm Infoblox described the threat actor as likely affiliated with the People's Republic of China (PRC) with the ability to control the Great Firewall ( GFW ), which censors access to foreign websites and manipulates internet traffic to and from the country. The moniker is reference to the "bewildering" nature of their operations and the actor's abuse of DNS open resolvers – which are DNS servers that accept recursive queries from all IP addresses – to send queries from the Chinese IP space. "Muddling Meerkat demonstrates a sophisticated understanding of DNS that is uncommon among threat actors today – clearly pointing out...

Palo Alto Networks has shared more details of a critical security flaw impacting PAN-OS that has come under active exploitation in the wild by malicious actors. The company described the vulnerability, tracked as  CVE-2024-3400  (CVSS score: 10.0), as "intricate" and a combination of two bugs in versions PAN-OS 10.2, PAN-OS 11.0, and PAN-OS 11.1 of the software. "In the first one, the GlobalProtect service did not sufficiently validate the session ID format before storing them. This enabled the attacker to store an empty file with the attacker's chosen filename," Chandan B. N., senior director of product security at Palo Alto Networks,  said . "The second bug (trusting that the files were system-generated) used the filenames as part of a command."  It's worth noting that while neither of the issues are critical enough on their own, when chained together, they could lead to unauthenticated remote shell command execution. Palo Alto Networks sa...

Palo Alto Networks is warning that a critical flaw impacting PAN-OS software used in its GlobalProtect gateways is being actively exploited in the wild. Tracked as  CVE-2024-3400 , the issue has a CVSS score of 10.0, indicating maximum severity. "A command injection vulnerability in the GlobalProtect feature of Palo Alto Networks PAN-OS software for specific PAN-OS versions and distinct feature configurations may enable an unauthenticated attacker to execute arbitrary code with root privileges on the firewall," the company  said  in an advisory published today. The flaw impacts the following versions of PAN-OS, with fixes expected to be released on April 14, 2024 - PAN-OS < 11.1.2-h3 PAN-OS < 11.0.4-h1 PAN-OS < 10.2.9-h1 The company also said that the issue is applicable only to firewalls that have the configurations for both  GlobalProtect gateway  (Network > GlobalProtect > Gateways) and  device telemetry  (Device > Setup ...

Minecraft, with over 500 million registered users and 166 million monthly players, faces significant risks from distributed denial-of-service (DDoS) attacks, threatening server functionality, player experience, and the game's reputation. Despite the prevalence of DDoS attacks on the game, the majority of incidents go unreported, leaving a gap in awareness and protection. This article explains what happens to a Minecraft server during a DDoS attack and how to protect against such attacks. For an in-depth version of the article,  check out this white paper . When Creepers Breach: What Happens When an Attack Is Successful When a Minecraft server is hit with a DDoS attack, players may have problems with logging in to servers, loading worlds, navigating biomes, using tools, and chatting. They can also experience general lags, disconnections, timeouts, or server crashes. These in-game disruptions can ruin the gaming experience for players while causing financial and reputational losse...

Over 178,000 SonicWall firewalls exposed over the internet are exploitable to at least one of the two security flaws that could be potentially exploited to cause a denial-of-service (DoS) condition and remote code execution (RCE). "The two issues are fundamentally the same but exploitable at different HTTP URI paths due to reuse of a vulnerable code pattern," Jon Williams, a senior security engineer at Bishop Fox,  said  in a technical analysis shared with The Hacker News. The vulnerabilities in question are listed below - CVE-2022-22274  (CVSS score: 9.4) - A stack-based buffer overflow vulnerability in the SonicOS via HTTP request allows a remote, unauthenticated attacker to cause DoS or potentially result in code execution in the firewall. CVE-2023-0656  (CVSS score: 7.5) - A stack-based buffer overflow vulnerability in the SonicOS allows a remote, unauthenticated attacker to cause DoS, which could result in a crash. While there are no reports of exploi...

The cyber attacks targeting the energy sector in Denmark last year may not have had the involvement of the Russia-linked Sandworm hacking group,  new findings  from Forescout show. The intrusions, which  targeted around 22 Danish energy organizations  in May 2023, occurred in two distinct waves, one which exploited a security flaw in Zyxel firewall (CVE-2023-28771) and a follow-on activity cluster that saw the attackers deploy Mirai botnet variants on infected hosts via an as-yet-unknown initial access vector. The first wave took place on May 11, while the second wave lasted from May 22 to 31, 2023. In one such attack detected on May 24, it was observed that the compromised system was communicating with IP addresses (217.57.80[.]18 and 70.62.153[.]174) that were previously used as command-and-control (C2) for the now-dismantled  Cyclops Blink  botnet. Forescout's closer examination of the attack campaign, however, has revealed that not only were the t...
