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

New Juniper Junos OS Flaws Expose Devices to Remote Attacks - Patch Now

Aug 19, 2023 Network Security / Vulnerability
Networking hardware company Juniper Networks has released an "out-of-cycle" security update to address multiple flaws in the J-Web component of Junos OS that could be combined to achieve remote code execution on susceptible installations. The four vulnerabilities have a cumulative CVSS rating of 9.8, making them Critical in severity. They affect all versions of Junos OS on SRX and EX Series. "By chaining exploitation of these vulnerabilities, an unauthenticated, network-based attacker may be able to remotely execute code on the devices," the company  said  in an advisory released on August 17, 2023. The J-Web interface allows users to configure, manage, and monitor Junos OS devices. A brief description of the flaws is as follows - CVE-2023-36844  and  CVE-2023-36845  (CVSS scores: 5.3) - Two PHP external variable modification vulnerabilities in J-Web of Juniper Networks Junos OS on EX Series and SRX Series allows an unauthenticated, network-based attacker to

How to Handle Retail SaaS Security on Cyber Monday

How to Handle Retail SaaS Security on Cyber Monday

Nov 27, 2023SaaS Security / Cyber Monday
If forecasters are right, over the course of today, consumers will spend  $13.7 billion . Just about every click, sale, and engagement will be captured by a CRM platform. Inventory applications will trigger automated re-orders; communication tools will send automated email and text messages confirming sales and sharing shipping information.  SaaS applications supporting retail efforts will host nearly all of this behind-the-scenes activity. While retailers are rightfully focused on sales during this time of year, they need to ensure that the SaaS apps supporting their business operations are secure. No one wants a repeat of one of the biggest retail cyber-snafus in history, like when one U.S.-based national retailer had 40 million credit card records stolen.  The attack surface is vast and retailers must remain vigilant in protecting their entire SaaS app stack. For example, many often use multiple instances of the same application. They may use a different Salesforce tenant for eve

Juniper Releases Patches for Critical Flaws in Junos OS and Contrail Networking

Jul 18, 2022
Juniper Networks has pushed security updates to address  several vulnerabilities  affecting multiple products, some of which could be exploited to seize control of affected systems. The most critical of the flaws affect Junos Space and Contrail Networking, with the tech company urging customers to update to release versions 22.1R1 and 21.4.0, respectively. Chief among them is a collection of 31 bugs in the Junos Space network management software, including CVE-2021-23017 (CVSS score: 9.4) that could result in a crash of vulnerable devices or even achieve arbitrary code execution. "A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact," the company  said . The same security vulnerability has also been  remediated  in Northstar Controller in versions 5.1.0 Service Pack 6 and 6.2.2. Additionally, the
