New PoC Exploit for Apache ActiveMQ Flaw Could Let Attackers Fly Under the Radar

New PoC Exploit for Apache ActiveMQ Flaw Could Let Attackers Fly Under the Radar

Nov 15, 2023 Ransomware / Vulnerability
Cybersecurity researchers have demonstrated a new technique that exploits a critical security flaw in Apache ActiveMQ to achieve arbitrary code execution in memory. Tracked as  CVE-2023-46604  (CVSS score: 10.0), the vulnerability is a remote code execution bug that could permit a threat actor to run arbitrary shell commands. It was patched by Apache in ActiveMQ versions 5.15.16, 5.16.7, 5.17.6, or 5.18.3 released late last month. The vulnerability has since  come under   active exploitation  by ransomware outfits to deploy ransomware such as HelloKitty and a strain that shares similarities with TellYouThePass as well as a remote access trojan called SparkRAT. According to  new findings  from VulnCheck, threat actors weaponizing the flaw are  relying  on a public proof-of-concept ( PoC ) exploit originally disclosed on October 25, 2023. The attacks have been found to use  ClassPathXmlApplicationContext , a class that's part of the Spring framework and available within Active
Experts Warn of Severe Flaws Affecting Milesight Routers and Titan SFTP Servers

Experts Warn of Severe Flaws Affecting Milesight Routers and Titan SFTP Servers

Oct 17, 2023 Data Security / Network Security
A severity flaw impacting industrial cellular routers from Milesight may have been actively exploited in real-world attacks, new findings from VulnCheck reveal. Tracked as  CVE-2023-43261  (CVSS score: 7.5), the vulnerability has been described as a case of information disclosure that affects UR5X, UR32L, UR32, UR35, and UR41 routers before version 35.3.0.7 that could enable attackers to access logs such as httpd.log as well as other sensitive credentials. As a result, this could permit remote and unauthenticated attackers to gain unauthorized access to the web interface, thereby making it possible to configure VPN servers and even drop firewall protections. "This  vulnerability  becomes even more severe as some routers allow the sending and receiving of SMS messages," security researcher Bipin Jitiya, who discovered the issue,  said  earlier this month. "An attacker could exploit this functionality for fraudulent activities, potentially causing financial harm to the

Make a Fresh Start for 2024: Clean Out Your User Inventory to Reduce SaaS Risk

Make a Fresh Start for 2024: Clean Out Your User Inventory to Reduce SaaS Risk

Dec 04, 2023SaaS Security / Data Security
As work ebbs with the typical end-of-year slowdown, now is a good time to review user roles and privileges and remove anyone who shouldn't have access as well as trim unnecessary permissions. In addition to saving some unnecessary license fees, a clean user inventory significantly enhances the security of your SaaS applications. From reducing risk to protecting against data leakage, here is how you can start the new year with a clean user list.  How Offboarded Users  Still  Have Access to Your Apps When employees leave a company, they trigger a series of changes to backend systems in their wake. First, they are removed from the company's identity provider (IdP), which kicks off an automated workflow that deactivates their email and removes access to all internal systems. When enterprises use an SSO (single sign-on), these former employees lose access to any online properties – including SaaS applications – that require SSO for login.  However, that doesn't mean that former employee
Nearly 12,000 Juniper Firewalls Found Vulnerable to Recently Disclosed RCE Vulnerability

Nearly 12,000 Juniper Firewalls Found Vulnerable to Recently Disclosed RCE Vulnerability

Sep 19, 2023 Network Security / Exploit
New research has found that close to 12,000 internet-exposed Juniper firewall devices are vulnerable to a recently disclosed remote code execution flaw. VulnCheck, which  discovered  a new exploit for CVE-2023-36845, said it could be  exploited  by an "unauthenticated and remote attacker to execute arbitrary code on Juniper firewalls without creating a file on the system." CVE-2023-36845 refers to a  medium-severity flaw  in the J-Web component of Junos OS that could be weaponized by a threat actor to control certain, important environment variables. It was patched by Juniper Networks last month alongside CVE-2023-36844, CVE-2023-36846, and CVE-2023-36847 in an out-of-cycle update. A subsequent proof-of-concept (PoC) exploit devised by watchTowr combined CVE-2023-36846 and CVE-2023-36845 to upload a PHP file containing malicious shellcode and achieve code execution. The latest exploit, on the other hand, impacts older systems and can be written using a single cURL comma
Thousands of Unpatched Openfire XMPP Servers Still Exposed to High-Severity Flaw

Thousands of Unpatched Openfire XMPP Servers Still Exposed to High-Severity Flaw

Aug 24, 2023 Cyber Attack / Vulnerability
Thousands of  Openfire XMPP servers  are unpatched against a recently disclosed high-severity flaw and are susceptible to a new exploit, according to a  new report  from VulnCheck. Tracked as  CVE-2023-32315  (CVSS score: 7.5), the vulnerability relates to a path traversal vulnerability in Openfire's administrative console that could permit an unauthenticated attacker to access otherwise restricted pages reserved for privileged users. It affects all versions of the software released since April 2015, starting with version 3.10.0. It was remediated by its developer, Ignite Realtime, earlier this May with the release of versions 4.6.8, 4.7.5, and 4.8.0. "Path traversal protections were already in place to protect against exactly this kind of attack, but didn't defend against certain non-standard URL encoding for UTF-16 characters that were not supported by the embedded web server that was in use at the time," the maintainers  said  in a detailed advisory. "A

Critical MikroTik RouterOS Vulnerability Exposes Over Half a Million Devices to Hacking

Jul 26, 2023 Network Security / Vulnerability
A severe privilege escalation issue impacting MikroTik RouterOS could be weaponized by remote malicious actors to execute arbitrary code and seize full control of vulnerable devices. Cataloged as  CVE-2023-30799  (CVSS score: 9.1), the shortcoming is expected to put approximately 500,000 and 900,000 RouterOS systems at risk of exploitation via their web and/or Winbox interfaces, respectively, VulnCheck disclosed in a Tuesday report. "CVE-2023-30799 does require authentication," security researcher Jacob Baines  said . "In fact, the vulnerability itself is a simple privilege escalation from admin to 'super-admin' which results in access to an arbitrary function. Acquiring credentials to RouterOS systems is easier than one might expect." This is because the Mikrotik RouterOS operating system does not offer any protection against password brute-force attacks and ships with a well-known default "admin" user, with its password being an empty string
